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.

• Weight: Irrelevant
Install detector at 1 m height and set slider to Pet position

False alarm prevention:
• Dual motion detection technology
• SmartDetect software algorithm

Temperature compensation:
Ensures reliable motion detection from −25 °C to +60 °C

Recommendations
Installation height:
• 2.4 m for standard mode
