## Long description

AJAX-MotionProt+B black is a wireless passive infrared (PIR) motion detector designed for indoor security. The sensor detects changes in infrared radiation caused by human movement and communicates wirelessly with AJAX security systems to trigger alarms or automation scenes. Its compact black housing blends with interior decor while providing continuous monitoring of rooms, corridors and entryways to help protect property and inform users of unauthorised activity.
Advantages
The AJAX motion detector offers quick detection of human motion through a reliable PIR sensor combined with wireless connectivity for easy installation without running cables. Its black finish reduces visual contrast on dark surfaces and allows discrete placement. The device works with AJAX control units to provide near real-time notifications and can be integrated into broader security and automation scenarios. Low power consumption extends battery life, while built-in tamper protection notifies the system if the detector is removed or opened.
Suitable for
Indoor rooms in homes and apartments
