AJAX BASELINE PIR Outdoor Curtain White

The first line of defense
Curtain Outdoor Jeweller is a motion detector for covering the perimeter of a site with exceptional accuracy and a near-zero chance of false alarms. Featuring a unique optical system, the device looks over narrow sectors of up to 12 m long. Dual motion detection technology engaging two PIR sensors and one K-band microwave sensor allows filtering out false alarms caused by thermal noise, animals, or plants. Adjustable detection range and sensitivity, as well as two operating modes, make the device a perfect fit for any site. Pre-installed batteries ensure stable performance for up to three years.
