BBC BircherMotion Detection

Motion Detection

Microwave motion detectors trigger industrial doors and gates in response to vehicle or pedestrian movement, offering longer reach and better weather tolerance than passive infrared sensors. The Doppler-based operating principle is insensitive to ambient light, wind, and precipitation. Bircher motion detection products include adjustable sensitivity and detection zone settings to minimize false triggers and match the detection field to the entry geometry.
