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).

• The card must be formatted in FAT32 and no more than 32 GB in total capacity.
• Copy the two downloaded firmware files directly into the root directory of the card — do not place them inside a folder or rename it.

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.

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 to indicate the update is underway.
5. Wait approximately 30 seconds while the firmware updates.
6. When complete, the front LED will blink to confirm the update has finished successfully.
7. You can now remove the microSD card.

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

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.
