NICOR's Multi-Technology, advanced Occupancy Vacancy motion sensors accommodate 120V and 277V Volt applications while utilizing the latest Passive Infrared (PIR) and Ultrasonic technologies. Passive Infrared (PIR) monitors the patterns of background heat energy within a given space with technology that detects static heat signatures. Ultrasonic Technology is a highly advanced form of sensing motion. Ultrasonic sensors work similar to radar by sending out high frequency sounds waves, which cannot be detected by the human ear. The sound waves deflect and ricochet off the walls and furniture in the room and return to the motion sensor. When an object moves within this space, even behind furniture, the ultrasonic sensors will detect the change in sounds waves and trigger the system. With combined Ultrasonic and PIR, you will avoid any false ?On? or ?Off? triggers. This product may be the best on the market. Protected by NICOR?s 2 Year Limited Warranty.
