Adaptive motion sensitivity explained

Reconeyez detectors are equipped with a PIR-technology based motion sensor. This motion sensor triggers an alarm in case there is enough infrared radiation detected in the scanned environment, for example from the intruder's body heat. However, such radiation can be emitted or reflected by various other objects and sources in the environment, like sun, wind or rain. In order to filter out any false positive alarms triggered by the environment (like plants moving in the wind or sun reflections) the Reconeyez system is equipped with a server-level algorithm called the Adaptive motion sensitivity (AMS). Essentially, this is an automatic and real-time tool, that will keep the detector motion sensor at the most efficient sensitivity level that corresponds to the surrounding environment.

Here is how it works.

Adaptive motion sensitivity regime

By default all new Reconeyez detector have the adaptive motion sensitivity enabled.  This means that at all times a dedicated algorithm is monitoring the number of received Autodismissed alarms (no valid object detected on the triggered alarm photo). If the number of Autodismissed alarms exceeds the approved thresholds, then the detector motion sensitivity is automatically reduced by one step. Once the number of Autodismissed alarms drops, the algorithm again automatically and gradually restores the maximum sensitivity of the detector motion sensor. This ensures less false triggers during wind storms, heavy rain or specific angle of the sun at certain time of the day without any time consuming manual configuration.

Most of the time, when there are no extreme environmental impacts, detector motion sensor is kept at the maximum sensitivity level by the adpative motion sensitivity algorithm. AMS is an excellent tool for reducing the number of false alarms, reducing battery depletion and time wasted on constant manual configuration of devices.

Manual motion sensitivity regime

Users can also adjust the motion sensitivity manually by disabling the adaptive motion sensitivity button. Once it is disbaled, the manual slider (0-100) will appear. By default, it will automatically display the maximum (Very high) value. We advise to be cautious in reducing this parameter as this may result in the reduced ability of the sensor to detect intrusions. Should this be still necessary in edge cases, strict live testing under different environmential circumstances is advised (temperature, detection distance, background movement).

To check or change the motion sensitivity settings, please go to Devices menu and open any detector detailed view. Motion and tamper sensitivity settings are located at the bottom of the parameters view. Make sure to press Synchronize after changing the device settings to sync the changes to the detector.
