The device automatically adjusts its sensitivity to ensure reliable detection in both hot and cold conditions.

How to use

Mount the MotionProtect on a wall facing the area to be monitored, typically in front of doors or entry routes, using the SmartBracket mounting plate. The detector is supplied with a preinstalled battery; power it on and add the device to the Ajax hub using the mobile application with a single click. After pairing, verify the detection zone and adjust the bracket position if necessary to avoid blind spots.

Recommendations

Install the detector at a height recommended by the manufacturer, avoid pointing it at heat sources or air vents, and place it so that pets under 20 kg and 50 cm cannot cross directly in front of the sensor’s field of view to minimise false alarms. Test the detector after installation via the Ajax app and perform periodic checks to ensure correct operation.
