Sensitivity

The Sensitivity menu screen allows you to adjust how responsive the sensor is to motion across both lenses. This setting affects the overall detection sensitivity of the device.

Adjusting Sensitivity

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

2. Use the Up or Down buttons to change the value.

3. Press the Set button to save your selection.

Sensitivity can be set between 1 and 16, where:

• 16 = Maximum sensitivity (triggers from smaller or more distant movements).

• 1 = Minimum sensitivity (requires more pronounced movement to trigger).

After setting the overall sensitivity, you can fine-tune the relative sensitivity of the Far and Wide sensors on their respective menu screens.

[Placeholder: Insert explanation here about how the overall sensitivity interacts mathematically with the individual Far and Wide sensor sensitivities — e.g. whether this is a straight additive, multiplicative, or weighted relationship.]

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:

• Hold either the Up or Down button for more than 3 seconds while on the Sensitivity screen.

• When active, the display will show the “ON” indicator for Adaptive Sensitivity.

In this mode, the sensor dynamically adjusts its sensitivity in response to background activity levels:

• If there is persistent low-level motion or heat variation (for example, caused by wind-blown vegetation or rising heat during the middle of the day), the trigger threshold is automatically increased.

• When background movement decreases, the sensor gradually lowers the threshold again to regain full responsiveness.

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.
