PIR v4 Manual


Introduction

The Introduction provides an overview of the Camtraptions PIR Sensor v4 — explaining how passive infrared detection works, what’s new in this version, and how the sensor integrates into a camera-trap setup. It offers essential background for understanding the purpose and advantages of the PIR v4 system.

Introduction

What is a PIR Motion Sensor?

All objects emit invisible infrared radiation. A Passive Infrared (PIR) sensor detects changes in infrared energy within its field of view—such as when a warm-bodied animal passes in front.

The term “passive” refers to the fact that the sensor does not emit any radiation itself—it simply monitors the infrared radiation naturally emitted by objects in its surroundings. This makes PIR sensors extremely energy-efficient and reliable for long-term use in the field.

In a camera-trap setup, the PIR sensor’s role is to detect an animal’s presence and automatically trigger the connected photographic equipment, such as a DSLR or mirrorless camera. This enables the capture of high-quality photographs and video footage of wildlife with minimal human disturbance.

Introduction

What is New in Version 4?

Version 4 of the Camtraptions Passive Infrared (PIR) Motion Sensor represents a significant upgrade over previous models, introducing enhanced flexibility, usability, and performance. The following are the key new features and improvements:

Dual-Sensor System

Version 4 features dual PIR sensors—two independent detectors offering maximum flexibility.:

Each sensor can be controlled independently. Users can adjust their relative sensitivities, enable or disable either sensor, or assign different functions—such as using the wide sensor to wake connected camera equipment and the far sensor to trigger it.

New User Interface

A built-in display screen and button pad provide an intuitive, menu-driven setup process. Users can easily configure parameters such as:

This marks a major step forward in ease of use compared with previous generations.

Clock Integration

The new clock allows precise scheduling of the sensor’s active hours. Users can define a specific time window—down to the minute—when the sensor should operate, offering greater control and efficiency in the field.

Improved Battery System

Version 4 introduces support for NP-F lithium-ion batteries, which are widely used in photographic equipment and easy to source. With the largest NPF batteries, the standby of the sensor time equals or exceeds the previous model.

A 6xAA to NP-F battery adapter (purchased separately) allows the sensor to be powered by six AA batteries as an alternative. Batteries are easily and quickly swapped by opening the rear compartment and sliding them in or out.

The battery voltage can be checked quickly from the home screen.

Firmware Upgradability

Version 4 now supports firmware updates via microSD card, enabling users to easily install future software improvements and feature enhancements without returning the unit for servicing.

Enhanced Connectivity and Durability

Version 4 remains compatible with both wired and wireless triggering methods, giving users the flexibility to connect their cameras and flashes using cables or Camtraptions Wireless Receivers. The sensor works seamlessly with existing wireless channels and accessories, ensuring full backward compatibility with previous systems.

Several other refinements further improve robustness and versatility:

Introduction

Overview of the Sensor

The Camtraptions PIR Sensor v4 features a thoughtfully designed layout that balances functionality, durability, and ease of use. On the front, there are two motion sensors—one equipped with a built-in indicator light that is enabled during setup to show when motion is detected.

On the back, you’ll find the display screen and keypad, which includes the power (on/off) button. The rear side is also the battery door, which can be opened using the catch on the top to access the internal battery compartment.

The underside of the unit includes dual tripod mounting sockets for secure installation, as well as the wired output socket and DC power input, both protected by weather-sealed rubber cable bungs.

On the sides of the sensor are adjustable flaps that can be used to limit or refine the field of view of the sensors for more precise control. Beneath the right-hand flap is a small bung that covers the microSD card slot, which is used for firmware updates.

pir_front_label.png

pir_back_label.png

The information in this manual corresponds to firmware version 1.19. You can check the firmware version, and update it if necessary, by following the procedures on the firmware update page.

Getting Started

This section covers the fundamental steps for preparing your PIR Sensor for use — including powering, connecting, mounting, and aiming the unit. It guides you through initial setup so you can quickly get the sensor operational and ready for deployment in the field.

Getting Started

Powering Your Sensor

The Camtraptions PIR Sensor v4 can be powered in several different ways, offering flexibility for a wide range of field conditions and setup durations.

pir_battery.png

1. NPF-Type Rechargeable Battery

The primary power option is a Sony-type NP-F lithium-ion battery, a widely available and reliable standard used across the photographic industry. The PIR v4 is compatible with NP-F batteries up to the size of an NP-F970 and with a maximum height of 60mm. Note that some third-party manufacturers produce NP-F batteries with built-in USB-charging ports that exceed this height and will not fit inside the sensor.

NP-F batteries are sold separately, as they are easy to source locally from most camera or video equipment suppliers. Place the battery into the battery tray, about 1cm away from its fully engaged position. Apply slight downward force to ensure that the central locking tab in the battery tray is fully depressed and, at the same time, push the battery forward until it clicks into place.

To remove the battery, simply pull it backwards.

2. AA Battery Adapter

As an alternative, the sensor can be powered using six AA batteries installed in a 6xAA to NP-F battery adapter (sold separately). The adapter fits into the same mounting slot as the NP-F battery. This option provides flexibility in situations where rechargeable lithium batteries are not available or convenient to use.

To install, insert the adapter in the same way as an NP-F battery, ensuring it is seated securely before closing the rear door. The individual AA cells may be removed/inserted while keeping the adapter in-situ inside the PIR v4, or alternatively the entire adapter can be removed in the same way as an NP-F battery.

3. External DC Power Input

For extended deployments or fixed installations, the sensor can also be powered via the DC input jack located on the underside of the unit. The sensor accepts DC input voltages from 4V to 12V.

For added reliability in the field, the sensor is compatible with Camtraptions Waterproof Screw-lock DC connectors, which provide a more secure and weather-resistant connection.

Ensure that any internal battery is removed from within the PIR v4 before an external battery or power source is connected to the sensor. Internal batteries cannot be connected and used at the same time as an external power supply. The only exception to this is if you are connecting a small external solar panel to trickle charge 6x Ni-MH AA batteries inside the PIR v4.

Getting Started

Connecting Your Camera

The Camtraptions PIR Sensor v4 can trigger your camera in two ways: wirelessly or via a wired connection. Both methods are compatible with DSLR and mirrorless cameras that feature an external shutter-release socket.

1. Wireless Connection (Default)

The sensor includes a built-in wireless transmitter that communicates with Camtraptions Wireless Receivers. This is the simplest and most flexible way to set up your camera trap.

To establish a connection:

  1. Ensure the wireless channel on the sensor matches the channel setting on your wireless receiver.
  2. Plug the wireless receiver into your camera’s shutter-release socket using the appropriate Camtraptions camera connecting cable.

The wireless transmitter can be disabled in the menu if you prefer to operate the sensor via a wired connection.

2. Wired Connection

Alternatively, the sensor can be connected directly to the camera using a wired cable.

A robust and highly reliable direct connection is now created between the sensor and the camera.

PIRcables.png

A standard Camtraptions camera connecting cable or sensor extension cable can also be plugged into the sensor, but using these basic cables instead of the dedicated waterproof cable system will void the warranty of the PIR Sensor v4, as its weather-sealing will not be maintained.

Waterproof Cable Connection Tips

3. Choosing Between Wireless and Wired

Both connection types have advantages, depending on your setup requirements:

Connection Type Advantages Considerations
Wireless Fast and simple setup. No long cables between camera and sensor, allowing greater flexibility in positioning. Reduces risk of cables being pulled, damaged, or chewed by animals. Wireless receiver consumes additional power, impacting total standby time of the setup.
Wired Very power-efficient. Does not require a powered receiver. Immune to wireless interference and blocked or weak wireless signals. Requires a physical cable connection, limiting placement flexibility and adding potential for cable damage or disturbance.

In most cases, the wireless setup is preferred for its simplicity and flexibility, particularly when the sensor needs to be positioned several metres away from the camera. However, a wired setup is ideal when power efficiency is the priority or when the sensor and camera are mounted close together.

Camtraptions Wireless Receivers are designed for exceptional energy efficiency, making long-term wireless setups (lasting weeks or even months) possible when paired with larger batteries or solar power systems.

Getting Started

Mounting Your Sensor

The Camtraptions PIR Sensor v4 features two tripod sockets on the underside, providing flexible and secure mounting options for a wide range of setups.

pir_bottom_label.png

Single-Screw Mounting

For simple installations—such as when using a MightyPod or a third-party tripod—the sensor can be mounted using just one tripod socket.

Dual-Screw Mounting

For the most secure and stable mounting, particularly in outdoor or long-term deployments, a dual-screw setup can be used.

This prevents the sensor from twisting or shifting during installation or use. The socket spacing matches the standard used by the Camtraptions Jungle Mount System, enabling the sensor to be mounted on:

This system provides a robust, flexible solution for positioning the sensor in almost any environment.

When selecting a mounting method, ensure that the chosen mount does not obstruct the rear door of the sensor when it is opened. If the mount prevents the door from opening fully, forcing it may damage the hinge. Always allow sufficient clearance for the door to open freely for battery changes.

Getting Started

Controlling the Field of View

The field of view (FOV) of the Camtraptions PIR Sensor determines where an animal will be when the camera is triggered, making it a crucial part of composing your images—particularly for still photography. The field of view can be adjusted in several ways to precisely control the trigger zone.

side_flaps.png

1. Using the Adjustable Side Flaps

Each side of the sensor is fitted with a flap or blinker that can be used to limit the field of view of the PIR sensors.

By folding the flaps outward, you can block unwanted detection zones to either side, ensuring that the sensor only triggers when an animal is directly in front of it.

To adjust the flaps:

  1. Loosen the thumbscrew on each flap.
  2. Rotate the flap into the desired position to restrict the field of view as needed.
  3. Tighten the thumbscrew again to hold the flap firmly in place.

For best results, ensure that both flaps are positioned symmetrically, with the sensor aimed at the centre of the intended trigger zone. The PIR elements are most sensitive in the middle of their field of view, so symmetrical adjustment helps ensure that the sensor receives the strongest possible signal.

If you would like to reduce the field of view even further than the standard side flap positions allow, then you can undo the thumbscrews fully and swap the left and right flaps around. This makes it possible to achieve a very narrow angle resulting in an extremely precise trigger area.

Diagram showing flaps in reversed position:

flaps-reversed.png

2. Using the Dual-Sensor System

Version 4 includes two separate sensors, each with a different field of view:

By adjusting the relative sensitivity of these two sensors, or disabling one entirely, you can fine-tune the spread and range of the trigger zone.

It should also be noted that the Wide and Far sensors are both most sensitive to motion along the horizontal axis (sideways motion). They are less sensitive to upward/downward motion along the vertical axis.

3. Using the Indicator Light for Setup

One of the two front sensors includes a built-in red indicator light that can assist with setup. When the light is active, it briefly illuminates whenever motion is detected - helping you see exactly where the trigger zone begins and ends.

To use the indicator light:

  1. Turn on the sensor or press any button to activate setup mode.
  2. Walk or wave a hand in front of the sensor to observe where motion is detected.
  3. Adjust the sensor’s position or flap angles until the trigger zone aligns with your intended composition.

The indicator light remains active for five minutes after the last button press, after which it automatically disables to conserve power. For more details, see the Indicator Light section later in this manual.


Getting Started

Turning Your Sensor On and Off

The Camtraptions PIR Sensor v4 has been designed for maximum reliability in long-term field deployments. Its power-management system ensures that the sensor automatically recovers from any momentary power interruptions.

Automatic Power-On

The sensor automatically turns on as soon as power is connected.

This behaviour is intentional and provides an important reliability safeguard. If power is ever momentarily interrupted—for example, by a brief loss of contact with the battery or vibration in the field—the sensor will automatically restart and resume operation without requiring user input. This ensures that your setup continues functioning even after jolts or disconnections.

Manual Power Control

Once power is connected, the sensor can be turned on or off manually using the power button on the rear keypad:

Notes on Power Behaviour

This design guarantees the highest possible reliability in unattended camera-trap installations, ensuring the sensor always returns to active operation when power is restored.

Getting Started

The Home Screen

When the Camtraptions PIR Sensor v4 is powered on, it will display the Home Screen. This is the default screen shown when the sensor is idle and ready to detect motion. The Home Screen provides key information about the sensor’s current operating state at a glance.

Screen Indicators

The following elements are displayed on the Home Screen:

screen-s.png screen-v.png
screen-hometimeon.png screen-hometimeoff.png

screen-activity-logo.png

Button Shortcuts from the Home Screen

While on the Home Screen, pressing and holding certain buttons provides quick access to key information:

Button Hold Duration Function
Left 2 seconds Displays the current time set on the sensor’s internal clock — useful for quickly confirming the time setting.
Up 2 seconds Displays the current battery voltage, allowing you to check the remaining charge.
Right 2 seconds Displays the firmware version, so you can confirm you’re using the correct manual or check if an update is available.

From the quick access screens, wait 20 seconds or press any arrow key to return to the home screen.

Battery Voltage Reference

When viewing the battery voltage, the displayed value provides an indication of the remaining battery charge. The relationship between voltage and capacity varies depending on the battery type and chemistry. For convenience, detailed battery voltage reference tables are provided at the end of this manual, showing how measured voltage corresponds to approximate remaining charge for different compatible battery types.

Getting Started

Front Motion Indicator Light

The Front Motion Indicator Light is a useful tool for testing the sensor’s field of view and detection range during setup. When active, the light flashes red through the white PIR lens whenever motion is detected, helping you visualise exactly when and where the sensor is responding.

The indicator light remains active for five minutes after the sensor is first powered on or after any button is pressed. It then automatically disables to conserve power and to prevent the light from drawing attention to the sensor while it is deployed in the field.

The light is bright and visible in a wide range of lighting conditions, making it effective for setup in both indoor and outdoor environments.

  2. Wide Sensor – Control the behaviour and relative sensitivity of the wide-angle PIR sensor.

  3. Far Sensor – Control the behaviour and relative sensitivity of the narrow-field, long-range PIR sensor.

  4. Num (Number) – Define how many photos the sensor will take per detection (1–6).

  5. FPS (Frames Per Second) – Set the shooting interval between frames (0.25–3 fps).

  6. Gap – Specify a retrigger delay between sequences to control how soon the sensor is able to reactivate.

  7. Wake – Set a wake-up period to give cameras or flashes time to power up before triggering.

  8. Set Time – Adjust the sensor’s internal clock for accurate time-based functions.

  9. Time Mode – Enable or disable time windows that limit when the sensor is active.

  10. Set On Time – Define the time of day when the sensor becomes active.

  11. Set Off Time – Define the time of day when the sensor becomes inactive.

  12. External Wake – Schedule periodic half-press pulses to prevent connected equipment from sleeping.

  13. Set Mode – Switch between Still and Video operating modes.

After the Set Mode screen, pressing the right arrow again returns to the Home Screen.

Stills Mode

Still Mode Settings

When the sensor is set to Still Mode, two additional menu screens become available: Number (NUM) and Frame Rate (FPS). These control how many photos are taken and how quickly they are captured when motion is detected.

Number (NUM)

The Number screen lets you choose how many photos the camera will take each time motion is detected.

Adjusting the Number of Photos

  1. From the Home Screen, press the Right Arrow until you reach the NUM screen.
  2. Use the Up or Down buttons to select a value between 1 and 6.
  3. Press the Set button to save your selection.

This value determines the total number of photos that will be captured per detection event.

For example, setting NUM = 5 means the camera will take five photos each time the sensor detects motion.

screen-num-3.png

Frame Rate (FPS)

The Frame Rate (FPS) screen determines how quickly the photos in each sequence are taken — that is, how many frames are captured per second during a detection event.

Adjusting the Frame Rate

  1. From the Home Screen, press the Right Arrow until you reach the FPS screen.
  2. Use the Up or Down buttons to select the desired frame rate.
  3. Press the Set button to save your selection.

The available frame rate range is 0.25 to 3.0 FPS, where:

For example, if NUM = 5 and FPS = 1.0, the camera will take five photos over five seconds.

If FPS = 2.0, those same five photos will be captured over 2.5 seconds.

Notes

Stills Mode

Suggested Camera Settings (Stills)

The following guide provides a recommended starting configuration for your camera when using the Camtraptions PIR Sensor v4. These settings are designed to produce reliable, well-exposed results in a wide range of conditions, both day and night.

This configuration is just one example — feel free to experiment with different settings to achieve specific creative effects or adapt to particular lighting conditions.

This setup offers a dependable baseline that balances exposure, responsiveness, and image quality. Once you have verified that your sensor and flashes are triggering reliably, you can fine-tune exposure settings, flash ratios, or ISO limits to suit your specific environment and creative goals.

Video Mode

The Video Mode section outlines how to configure the sensor for video recording. It details trigger signal behaviours, extend-on-motion options, and timing parameters. This mode enables reliable video capture of wildlife behaviour using either natural or artificial lighting.

Video Mode

Video Mode Menu Overview

When the sensor is set to Video Mode, pressing the right arrow from the Home Screen will cycle through the following menu screens in order. Each screen allows configuration of a key parameter controlling how the sensor detects motion and manages video recording. After the final screen, the menu loops back to the Home Screen.

  1. Wireless Channel – Set or disable the wireless transmission channel used to communicate with Camtraptions receivers.
  2. Wide Sensor – Control the behaviour and relative sensitivity of the wide-angle PIR sensor.
  3. Far Sensor – Control the behaviour and relative sensitivity of the narrow-field, long-range PIR sensor.
  4. Time (Recording Length) – Define the duration of each video recording following a detection.
  5. Gap – Set a retrigger delay between recordings to manage how soon the sensor is able to reactivate.
  6. Extend Time (EXT) – Enable or disable Extend Mode. When enabled, motion detected during recording resets the timer, extending the clip until motion stops or the maximum limit is reached.
  7. Video Mode (Signal Type) – Select the type of control signal used to start and stop video recording, depending on camera brand: 1 Press, 2 Press, or Hold mode.
  8. Wake Time – Configure a wake-up period to give cameras time to power up before recording begins.
  9. Set Time – Adjust the internal real-time clock to ensure accurate time-based operation.
  10. Time Mode – Enable or disable time windows that restrict when the sensor is active.
  11. Set On Time – Define the time of day when the sensor becomes active.
  12. Set Off Time – Define the time of day when the sensor becomes inactive.
  13. External Wake – Schedule periodic half-press pulses to prevent connected equipment from entering deep sleep.
  14. Set Mode – Switch between Video and Still operating modes.

After the Set Mode screen, pressing the right arrow again returns to the Home Screen.

Video Mode

Video Mode Settings

When the sensor is set to Video Mode, three additional menu screens become available: Recording Time (TIME), Extend Time (EXT TIME), and Video Trigger Mode (MODE). These settings control how long the camera records, whether recordings are extended when movement continues, and how the sensor communicates with your camera model.

Recording Time (TIME)

The Recording Time screen sets how long the sensor will command the camera to record each time motion is detected.

Adjusting the Recording Time

  1. From the Home Screen, press the Right Arrow until you reach the TIME screen.
  2. Use the Up or Down buttons to adjust the recording duration in seconds.
  3. Press the Set button and then use the Up or Down buttons to adjust the recording duration in minutes.
  4. Press the Set button to confirm and save.

The duration can be set from 10 seconds up to 15 minutes 59 seconds using the same adjustment method as other time-based settings.

This value represents the length of each video clip triggered by motion detection.

screen-video-time.png

Extend Time (EXT TIME)

The Extend Time option determines whether new motion detected during a recording will extend the recording duration. The Extend Time will be added to the remaining recording time from the moment that the last motion was detected.

This feature is useful for capturing continuous activity without cutting off prematurely when animals remain in view. 

Adjusting the Extend Time

  1. From the Home Screen, press the Right Arrow until you reach the EXT TIME screen.
  2. Use the Up or Down buttons to adjust the number of seconds to extend the recording time by, from between 10s and 99s (10s by default).
  3. Press the Set button to confirm and save.

Enabling or Disabling Extend Time

  1. Navigate to the EXT TIME screen.
  2. Press and hold the Up or Down button to toggle between ON and OFF.
  3. Press Set to confirm.

screen-video-ext-time.png

Example:

If the Recording Time is 1 minute, the Extend Time is 30 seconds and new motion is detected 45 seconds into the recording, then the clip length would be 45s + 30s for a total clip length of 1 minute 15 seconds.

Note: C Var 6 (see the Custom Variables section) can be used to limit the total recording length when Extend Time is enabled.

Video Trigger Mode (MODE)

The Video Mode screen defines how the sensor sends start and stop signals to the camera. Different camera brands and models interpret these signals differently, so selecting the correct mode ensures reliable video triggering.

screen-video-mode.png

Mode Description Compatible Systems
1 Sends a full-press signal to start recording, then repeats a full-press signal every 10 seconds to maintain recording. If more than 10 seconds elapse without a signal, the camera automatically stops recording. Sony cameras connected to the Camtraptions Sony Video Cable v2.
2 Sends a full-press signal to start recording and another full-press signal to stop recording. Most Canon and Nikon mirrorless cameras.
H Sends a wireless full-press signal to start recording, then repeats a full-press signal every 10 seconds to maintain recording. The sensor holds a wired full-press signal for the entire length of the video. Used to activate equipment requiring a constant full-press signal.

Mode 1 is typically the most reliable, as it ensures that if any trigger signal is missed, the camera will automatically stop recording instead of continuing indefinitely or becoming out of sync with the sensor’s start/stop commands.

Mode 2 - Many cameras (including Canon and Panasonic models among others) that operate using Mode 2, also need an intial half-press signal, followed by a pause, so that they fully wake up first before starting a recording. This initial half-press signal + pause can be added using the global Wake Time setting.

Mode 2 - If a button on the sensor is pressed during a recording then the sequence will be cancelled and not completed. This means a camera may not receive the stop recording signal and will continue recording unless manually stopped.

Video Mode

Suggested Camera Settings (Video)

When using the Camtraptions PIR Sensor in Video Mode, camera setup will depend largely on creative goals and equipment preferences. This section focuses on the key settings that ensure reliable operation when the camera is controlled by the sensor, rather than prescribing specific exposure or quality settings.

For Nikon and Canon cameras, the camera’s menu settings must be configured to allow the shutter button to start and stop video recording. Enabling this option ensures the camera can respond correctly to trigger signals sent via the shutter release socket, allowing the sensor to start and stop video recording automatically.

Global Settings

The Global Settings apply to both Still and Video modes. These settings control the core behaviour of the sensor and remain active regardless of which shooting mode is selected. Global Settings include options such as Wireless Channel, Sensitivity, and the Far/Wide Sensor configuration. These settings define how the sensor detects motion and communicates with connected equipment.

Global Settings

Wireless Channel

The Wireless Channel menu screen allows you to select which wireless channel the sensor’s built-in transmitter will use to communicate with your Camtraptions Wireless Receiver.

screen-channel.png

Accessing the Wireless Channel Setting

  1. From the Home Screen, press the Right Arrow button until you reach the Wireless Channel screen.
  2. Use the Up or Down buttons to change the wireless channel number.
  3. Press the Set (centre) button to save your selection.

The selected channel must match the channel set on your Camtraptions Wireless Receiver for proper operation.

Available Channels

The sensor supports 15 wireless channels, numbered 1–15. Each corresponds directly to the same numbered channel on the Camtraptions Wireless Receiver.

Wireless channels

Disabling Wireless Transmission

To disable the wireless transmitter completely (for wired-only operation):

The display will show “OFF”, indicating that wireless transmission is disabled.

In this mode, the sensor will only trigger connected devices via the wired output socket. It will also conserve some power and allow the sensor to operate for even longer in the field.

Global Settings

Wide Sensor

The Wide Sensor menu screen allows you to adjust the behaviour and sensitivity of the wide-angle PIR lens. This sensor has a broader field of view (approximately 60°) and is ideal for detecting animals earlier as they approach the camera.

screen-widesenson.png
screen-widesenswake.png screen-widesensoff.png

Accessing the Wide Sensor Screen

  1. From the Home Screen, press the Right Arrow repeatedly until you reach the Wide screen.
  2. Use the Up or Down buttons to adjust the sensitivity between 1 and 16, where:
    • 16 = Maximum sensitivity (detects smaller or more distant motion).
    • 1 = Minimum sensitivity (detects only close or pronounced motion).
  3. Press the Set button to save your chosen setting.

Testing the Wide Sensor

To understand and fine-tune how the wide sensor behaves in your setup:

Testing each sensor individually can help you visualise their detection ranges and ensure the trigger zone aligns precisely with your intended framing.

Changing the Wide Sensor Function

You can also change how the wide sensor behaves by pressing and holding either the Up or Down button for more than 2 seconds. This cycles through three operating modes:

Mode Description
Normal The sensor behaves normally, triggering the camera or flash when motion is detected.
Off The wide sensor is disabled and will not detect motion or trigger the camera.
Wake The wide sensor will only send a wake signal to connected camera equipment when motion is detected, but not a full trigger signal.

The Wake mode is particularly useful because the wide sensor often detects animals entering the frame before the far sensor does. Using it to send a wake signal ensures that by the time the far sensor sends the shoot signal, the camera (and any connected flashes) are already active and ready to respond.

This function is especially beneficial for:

Note: Camtraptions Z Pro Flashes remain fully charged and ready to fire instantly, so this feature is not required when using Z Pro units.

Note: If a sensor is set to Wake mode, then the signal will only be sent if the PIR v4 has not been active within the last 30 seconds. This ensures that no unnecessary wake signals (and potential trigger delays) are occuring during periods of continuous activity in front of the PIR.

Global Settings

Far Sensor

The Far Sensor menu screen allows you to adjust the behaviour and sensitivity of the long-range PIR lens. This sensor has a much narrower field of view (approximately 10°) and is significantly more sensitive overall than the wide sensor. It is designed for precise control of the trigger zone, enabling the user to determine exactly where in the frame the animal will be when the camera is activated.

Because of its narrow detection zone, the far sensor can be used much like a “beam break”, ideal for cutting across an animal trail or pathway to ensure triggering occurs only when the subject reaches a specific point.

screen-farsenson.png screen-farsensoff.png

Accessing the Far Sensor Screen

  1. From the Home Screen, press the Right Arrow repeatedly until you reach the Far screen.
  2. Use the Up or Down buttons to adjust the sensitivity between 1 and 16, where:
    • 16 = Maximum sensitivity (detects very small or distant motion).
    • 1 = Minimum sensitivity (detects only close or pronounced motion).
  3. Press the Set button to save your chosen setting.

Testing and Positioning the Far Sensor

To understand and fine-tune the detection range and behaviour of the far sensor:

Because its range is very long, the far sensor may sometimes detect motion beyond the intended trigger zone or outside the camera’s framing.

To prevent unwanted detections, it can be effective to mount the sensor slightly higher and angle the far sensor downward toward the desired trigger area. This positioning limits its view of distant background areas and ensures it primarily “sees” the ground where the subject will pass, triggering reliably and precisely when the animal enters the frame.

Changing the Far Sensor Function

As with the wide sensor, you can change the behaviour of the far sensor by pressing and holding either the Up or Down button for more than 2 seconds. This cycles through three operating modes:

Mode Description
Normal The sensor behaves normally, triggering the camera or flash when motion is detected.
Off The far sensor is disabled and will not detect motion or trigger the camera.
Wake The far sensor sends only a wake signal to connected camera equipment but does not trigger a full shoot command.

The Normal mode is typically used for capturing the actual trigger moment. However, in some advanced setups, the Wake mode may be used strategically to coordinate multiple sensors or fine-tune camera wake-up behaviour.

Global Settings

Gap Time

The Gap Time setting controls the delay between triggers, defining how long the sensor will wait before it can activate again after completing a sequence. This lets you control how often the sensor triggers, conserving battery power and storage while allowing flashes to recharge and reducing the chance of disturbing subjects.

screen-gap.png

Adjusting the Gap Time

  1. From the Home Screen, press the Right Arrow until you reach the Gap Time screen.
  2. Use the Up or Down buttons to set the desired delay between 0.5s and 1min (1s by default).
  3. Press the Set button to save your selection.

The chosen value determines how long the sensor will remain inactive after completing a sequence before it can trigger again.

Practical Uses

Adjusting the Gap Time can help you:

In most cases, a moderate delay provides the best balance between responsiveness and conservation of resources. For fast-moving subjects or short-term deployments, a shorter delay may be preferable, while for long-term camera traps, a longer delay could help extend system endurance.

Global Settings

Wake Time

The Wake Time setting determines how long the sensor will wait after an initial half-press (wake) signal has been sent to the camera before beginning the main trigger sequence. This gives the camera (and any connected flashes) time to wake up or prepare before the full trigger (shoot) command is sent.

screen-wake.png

Adjusting the Wake Time

  1. From the Home Screen, press the Right Arrow until you reach the Wake Time screen.
  2. Use the Up or Down buttons to select the desired delay in seconds between 1s and 15s.
  3. Press the Set button to save your selection.

The delay can be configured in seconds, depending on how much wake-up time your camera or flashes require. By default, this setting is off (no wake-up signal and delay).

Enable or Disable the Wake Function

Purpose of Wake Time

Some cameras require a short period to power up or establish communication before they will respond to a full trigger signal. If a shoot signal arrives too soon after the system has been idle, the camera may miss it entirely. This can lead to missed shots in still mode and, more critically, problems in video mode.

For example:

Adjusting this delay ensures reliable operation by waking connected equipment first, then triggering the shutter or video start signal once everything is ready.

Global Settings

Set Clock Time

The Set Clock Time screen allows you to configure the sensor’s internal clock, which is required for Time Windows (scheduled active hours). Setting the correct time ensures the sensor operates accurately within any defined time periods.

screen-set-time.png screen-set-time-min.png

Setting the Clock

  1. From the Home Screen, press the Right Arrow until you reach the Set Clock Time screen.
  2. Press the Up or Down buttons to adjust the hour value.
  3. Press the Set button to confirm the hour.
  4. The minute value will then begin flashing — use the Up or Down buttons to adjust it.
  5. Press Set again to save the time.

The clock uses a 24-hour format (00:00 to 23:59).

Note: The clock setting is retained internally, even when the sensor is powered off or the battery is removed.

Note: For accurate operation of Time Windows, ensure the clock is set to local time in the location where the sensor is being deployed.

Global Settings

Enable Time Windows

The Time Windows setting allows you to control when the sensor is active during a 24-hour period. When enabled, the sensor will automatically disable itself outside the defined time window, allowing it to operate only during selected hours (for example, nighttime only or daytime only operation).

screen-time-mode.png

Enabling or Disabling Time Windows

  1. From the Home Screen, press the Right Arrow until you reach the Time Windows screen.

  2. Press the Up or Down button to toggle between ON and OFF.

When Time Windows are enabled, a clock icon will appear on the Home Screen, indicating that scheduled operating hours are active. The clock icon on the Home Screen will be accompanied by either ON or OFF. This provides a convenient indication of whether the sensor is currently inside an active time window (ON) and is therefore working, or outside an active time window (OFF) and is therefore is disabled.

Notes on Operation

Future firmware updates may introduce the ability to configure multiple time windows. If multiple time windows would be a valuable feature for your application, please contact Camtraptions for updates or to provide feedback.

An active Time Window may cause the sensor to appear unresponsive. If the sensor does not seem to react to motion, first check whether the clock icon is visible on the Home Screen and if the activity indicator is displaying OFF. If it is, verify that the internal clock and time window settings are correct.

Global Settings

Set On Time

The Window On Time setting defines the time of day when the sensor becomes active — in other words, the start of the period during which motion detection and triggering are enabled.

This feature works in conjunction with the Time Windows setting. For example, if you wish the sensor to operate only at night, you might set the Window On Time to 18:00 (6:00 p.m.) and the Window Off Time to 06:00 (6:00 a.m.).

screen-set-on-time.png

Setting the Window On Time

  1. From the Home Screen, press the Right Arrow until you reach the Window On Time screen.
  2. Use the Up or Down buttons to adjust the hour value.
  3. Press the Set button to confirm the hour.
  4. The minute value will then begin flashing — use the Up or Down buttons to adjust it.
  5. Press Set again to save the time.

The time is entered in 24-hour format (00:00 to 23:59).

Notes

Global Settings

Set Off Time

The Window Off Time setting defines the time of day when the sensor becomes inactive, marking the end of the period during which motion detection and triggering are enabled.

This setting works together with the Window On Time to establish the daily operating period for the sensor. For example, if you want the sensor to operate only at night, you might set the Window On Time to 18:00 (6:00 p.m.) and the Window Off Time to 06:00 (6:00 a.m.).

screen-set-off-time.png

Setting the Window Off Time

  1. From the Home Screen, press the Right Arrow until you reach the Window Off Time screen.
  2. Use the Up or Down buttons to adjust the hour value.
  3. Press the Set button to confirm the hour.
  4. The minute value will then begin flashing — use the Up or Down buttons to adjust it.
  5. Press Set again to save the time.

The time is entered in 24-hour format (00:00 to 23:59).

Notes

Global Settings

External Wake

The Periodic External Wake setting allows the sensor to send a brief half-press (wake) signal to the connected camera or flash equipment at regular intervals. This periodic signal helps prevent certain devices from entering deep sleep modes and ensures they remain responsive for long-term deployments.

screen-periodic-wake.png

Purpose of Periodic Wake

This feature can be useful for a variety of situations, including:

Although there are several potential uses, the main purpose of this setting is to maintain camera responsiveness in systems that may otherwise power down or lose connection over extended periods of inactivity.

Setting the Periodic Wake Interval

  1. From the Home Screen, press the Right Arrow until you reach the Periodic Wake screen.
  2. Use the Up or Down buttons to adjust the desired time interval in hours and minutes, from a minimum of 1 minute to a maximum of 24 hours.
  3. Press the Set button to confirm and save your setting.

The interval can be configured in minutes and hours, and the sensor will send a brief wake signal to the connected equipment at each interval.

Enable or Disable the Periodic Wake Function

Panasonic cameras, such as the Panasonic GH4 and GH5, can enter a deep sleep state after extended inactivity. To prevent this, set a Periodic Wake interval of around 11 hours. This ensures the sensor sends a brief wake signal periodically, keeping the camera responsive during long deployments.

Notes

Advanced Configuration

Advanced Configuration provides in-depth control through Custom Variables (C Vars), allowing you to fine-tune signal durations, flash behaviour, and specialist functions. It also explains how to restore factory defaults and manage complex custom setups safely.

Advanced Configuration

Custom Variables

The Custom Variables menu provides access to advanced configuration options that allow the behaviour of the sensor to be fine-tuned. These variables modify timing parameters that affect how the camera is triggered, how long signals are held for, and other aspects of sequence timing. For the majority of users, customising these settings is generally unnecessary.

In some cases, enabling or adjusting a Custom Variable may override standard Still or Video Mode settings, resulting in slightly different sequence timing than expected. These options are intended for advanced users who require precise control over the triggering sequence.

Accessing Custom Variables

  1. From the Home Screen, press and hold the Left and Right Buttons simultaneously for more than 2 seconds until the Custom Variables (C VAR) screen appears.
  2. Use the Left and Right buttons to select the desired variable number.
  3. Use the Up and Down buttons to select the desired variable value.
  4. Press Set to save the new value.
  5. Some custom settings can also be enabled or disabled by holding the Up or Down button for more than 2 seconds to toggle them On and Off.

screen-cvar1.png

Leaving the Custom Variable Menu

From the custom variable menu, you can return to the Home Screen by either:

Available Custom Variables

C Var Description Default Value Adjustable Range
0 Sampling Frequency / Adaptive Sensitivity – Fine-tune the sensor sensitivity and response speed. 8 1-16
1 Half-Press Length (Before Full Press) – Determines how long the half-press (wake) signal is held before the full-press trigger in both still and video modes. 0.1 s 0.1–5.0 s (in 0.1 s steps)
2 Half-Press Length (After Full Press) – Determines how long the half-press signal is held after the full-press trigger in both still and video modes. 0.1 s 0.1–5.0 s (in 0.1 s steps)
3 Full-Press Duration (Still Mode) – If enabled, this overrides the full-press timing determined by the FPS setting. — 0.1–2.9 s (in 0.1 s steps)
4 Gap Between Full-Press Signals (Still Mode) – When Number (NUM) > 1, this defines the interval between shots. If enabled, it overrides the FPS-determined interval. — 0.1–15.0 s (in 0.1 s steps)
5 Full-Press Duration (Video Mode) – Defines how long the full-press signal is held when starting or maintaining a video recording. 1.0 s 0.1–2.9 s (in 0.1 s steps)
6 Maximum Video Length Extension Limit – Sets an absolute maximum video extension length in minutes. This limits the total recording duration when Extend Time is enabled. The maximum recording time will be this variable plus the standard recording time. — 1–60 min

7

Flash Wake / Flash Fire Signals – Controls whether flash trigger signals are sent during still sequences:
• 0 – No flash wake or fire signals sent.
• 1 – A 0.2 s Flash Wake signal is sent immediately before the first camera trigger signal in any still sequence.
• 2 – A 0.2 s Flash Wake signal is sent immediately before the first camera trigger signal, and a 0.2 s Flash Fire signal is sent after every camera trigger signal in the sequence.

To restore factory defaults, see the Reset to Defaults section.

Adjusting Custom Variables can affect the timing of the camera’s wake, trigger, and release signals.

Advanced Configuration

Custom Variable 0

The C Var 0 menu screen allows you to adjust how responsive the sensor is to motion across both lenses. It controls how frequently the sensor is taking measurements to look for movements (changes in infrared radiations) across its field of view. Taking more frequent measurements means that the sensor will be able to pick up smaller or more fleeting movements that might otherwise be missed if it is sampling less frequently.

This is different to the main far & wide sensitivity setting which relate to the amplitude of the infrared signal required to trigger the sensor, i.e. how warm, large or close the subject must be.

screen-cvar0off.png

Adjusting Sampling Frequency

  1. From the C Var 0 screen, use the Up or Down buttons to change the value.

  2. Press the Set button to save your selection.

Sampling Frequency can be set between 1 and 16 (the default is 8), where:

At higher sampling frequencies, the sensor will consume slightly more power and may be more susceptible to false triggering from wind, vegetation or dappled light, but it will be more effective at detecting small, rapidly moving subjects. Therefore, you should look to optimise the sampling frequency based on the intended subject, the environmental conditions and your battery life requirements.

Adaptive Sensitivity Mode

The sensor also features an Adaptive Sensitivity algorithm designed to help reduce false triggers in challenging environments.

To enable or disable Adaptive Sensitivity:

screen-cvar0.png

In this mode, the sensor dynamically adjusts its primary sensitivity thresholds, i.e. the thresholds that relate to the main far & wide sensitivity settings (not the sampling frequency) in response to background activity levels:

This adaptive behaviour helps the sensor remain effective while reducing false detections under fluctuating environmental conditions.

In most circumstances, Normal Sensitivity Mode provides sufficient control. However, if false triggers occur intermittently — such as at certain times of day or under windy or hot conditions — Adaptive Sensitivity Mode could improve reliability.

Advanced Configuration

Custom Variable 1

Using Half-Press Duration for Autofocus (C Var 1)

C Var 1 controls the length of the half-press (HP) signal that is sent to the camera before the full-press (FP) trigger. By extending this half-press duration, the sensor gives the camera time to perform autofocus functions before the image is taken.

With newer mirrorless cameras offering highly advanced autofocus systems — including animal-eye detection — this feature allows autofocus to be used in camera-trap setups for the first time.

When the half-press signal is active, the camera can detect and focus on the subject before the shutter is triggered, enabling the possibility of shooting with a shallow depth of field and precise eye focus, creating images that differ greatly from traditional manual-focus camera-trap photos.

Practical Considerations

This setting introduces a new creative approach to camera trapping — enabling autofocus precision and shallow-depth-of-field imagery previously impractical with PIR triggers. While manual focus remains the most dependable method for critical work, C Var 1 offers an exciting opportunity to experiment with modern autofocus systems for more dynamic and cinematic results.

Advanced Configuration

Custom Variables 7 and 8

Wireless Flash Wake and Flash Fire (C Var 7 & C Var 8)

C Var 7 and 8 provide advanced control for managing external flashes, particularly in situations where the camera cannot wake or trigger flashes automatically. This feature is especially useful with Sony cameras, which do not send a wake signal to flashes before triggering them.

While flashes such as the Camtraptions F1 and Z2 do not require a wake signal, the Camtraptions Z Pro achieves much longer standby times by entering a low-power sleep mode. As a result, it must be woken before it can be triggered.

In such cases, the sensor can take over flash control independently:

The wireless channel used for these flash signals is defined by C Var 8, which can be set between 1 and 15. This should be set to a different channel than the main camera trigger channel.

The C Var 7 = 2 configuration is particularly effective for night-time photography, where long shutter speeds allow the flash to fire during the exposure window.

As long as the shutter speed is longer than the Full-Press duration, the flash will fire within the open exposure, even when the camera itself is not controlling the flash. The Full-press duration can be customised using C Var 3 so that the flash fires as quickly as possible after the camera shutter opens.

This setup provides a reliable and flexible method to trigger flashes entirely via the sensor, simplifying configurations where cameras have limited flash-control capabilities or when using off-camera flash systems in low-light environments.

Advanced Configuration

Reset to Defaults

From the Custom Variables (C Var) menu, if you continue scrolling past the last C Var entry, you will reach a screen labelled “reset”. This screen allows you to restore all sensor settings to their factory defaults.

This is useful if many settings or Custom Variables have been adjusted and you want to quickly return the sensor to its original standard behaviour.

screen-reset.png

Performing a Reset

  1. Navigate to the Custom Variables (C Var) menu.
  2. Continue scrolling using the Right Arrow until you reach the “reset” screen.
    • The word “reset” will appear without blinking.
  3. Press the Up or Down button once — the word “reset” will begin blinking, indicating that the reset function is armed.
  4. Press the Set button to confirm.
    • The text “reset” will disappear.
    • The clock symbol will blink for approximately 3 seconds, indicating the reset is in progress.
    • When complete, the sensor will automatically return to the Home Screen.

Cancelling a Reset

If, while “reset” is blinking, you press Left or Right instead of Set, the screen will move back to the previous or next C Var setting, and no reset will be performed.

Notes

Maintenance and Care

This section covers best practices for maintaining the sensor’s performance and reliability. Topics include weatherproofing, cleaning, and firmware updates — ensuring your equipment remains dependable in harsh field environments.

Maintenance and Care

Weatherproofing

The Camtraptions PIR Sensor v4 is built for reliable operation in demanding outdoor conditions. However, regular checks and care are essential to maintain its weather resistance and ensure dependable long-term performance.

1. Check and Clean Seals

The main seal around the battery door is critical to maintaining a watertight enclosure.

2. Protect Unused Openings

All external ports and access points should be securely sealed when not in use.

3. Use Silica Gel

In all environments, but particularly in wet or humid conditions, it is recommended to place a small sachet of silica gel inside the battery compartment. There is space beside the battery for this purpose.

This simple precaution can significantly enhance the longevity and reliability of the sensor in challenging climates.

4. Avoid Submersion or Flood Risk

The sensor is weather-resistant but not waterproof. It is not designed to be submerged and should not be deployed in locations where it could be flooded — for example, in areas prone to rising water, heavy runoff, or riverbank overflow. Always mount the sensor in a position where it remains above likely water levels.

5. Freeze-thaw Precautions

In cold, wet environments, water could accumulate in the seam between the battery door and the main enclosure body. If temperatures drop below freezing, this water can turn to ice and expand, placing pressure on the door latch and potentially compromising the seal.

To minimise this risk, you can apply a wide strip of waterproof tape around the door joint—running from one lower corner of the enclosure, across the top of the latch, and down to the opposite lower corner. This simple precaution helps prevent water from pooling in the seam, reducing the likelihood of freeze-related damage during cold, wet deployments.

Maintenance and Care

Firmware Update

The Camtraptions PIR Sensor v4 supports firmware updates via microSD card. This allows new features, improvements, and bug fixes to be installed easily by the user without returning the sensor for servicing.

This manual applies to firmware version 1.19. Check the sensor's current firmware version by navigating to the Home Screen and holding down the right arrow button for 2 seconds. If necessary, you can update the firmware by following the instructions below.

Downloading Firmware

The latest firmware releases can be downloaded from the Camtraptions website:

camtraptions.com/resources/pir-v4/

Each firmware version will include a short description of changes.

Preparing the microSD Card

To perform a firmware update, you will need a microSD memory card (not supplied).

sdcontents.png

Inserting the microSD card

You may find it helpful to use a pair of thin-nose pliers to insert the SD card into the sensor. The card slot is located beneath the right-hand flap on the side of the sensor. Remove the bung and insert the SD card so that the edge of the card is flush with the edge of the board.

microsdbung.png

microsdcarddiagram.png

It is possible to accidentally drop the microSD card into the sensor. If this happens then just turn it over and shake it until the card falls out again.

Installing the Firmware

  1. Ensure a fully charged battery is installed in the sensor.
  2. Insert the prepared microSD card into the card slot beneath the right-hand flap.
  3. Hold the Down button while switching the sensor on to begin the update process.
  4. The screen will not display anything but the red indicator light on the front of the sensor will turn on and shine constantly to indicate that the update is underway.
  5. Wait approximately 30 seconds while the firmware updates.
  6. When complete, the front LED will blink briefly to confirm the update has finished successfully. The sensor's LCD screen will automatically turn on.
  7. You can now remove the microSD card carefully using thin-nose pliers and re-insert the rubber card slot bung, making sure it is fully seated.

Do not remove the battery or power during the update process, as this could interrupt installation and corrupt the firmware.

If the microSD card is not inserted correctly (or not inserted at all) and the update procedure is commenced using the sensor's keypad, then the red LED will flash rapidly to indicate an error. To resolve this, remove the battery from the sensor to turn it off, then make sure the microSD is correctly inserted before re-attempting the firmware update procedure.

Verifying the Update

To confirm the update was successful:

  1. From the Home Screen, hold the Right button to display the new firmware version.
  2. Check that the displayed version matches the firmware file you installed.

If the version number does not match or the sensor does not boot normally, repeat the update process using a freshly formatted microSD card.
