Bosch DS9371 Motion Sensor

The DS9371 TriTech detector can be used on ceilings as high as 7.6 m (25 ft). The combination of passive-infrared (PIR) detection, microwave detection, and advanced signal processing techniques allows TriTech detectors to rapidly respond to human targets without triggering false alarms from other sources. With three separate fully-adjustable PIR sections, coverage can be customized for specific areas at all mounting heights.
