Exclusive range-control Motion Detector
 
Dual Technology Motion Sensors offer new, easy solutions for your most challenging residential or commercial applications. Using a sophisticated combination of precision controlled microwave and passive infrared (PIR) technologies, these sensors give you total Coverage-on-Deman! A jumper switch allows you to quickly select from a variety of precise range settings. Coverage-on-Demand ensures that the sensor detects only objects within a precise area, and not in adjacent rooms or outside梐 common problem for less sophisticated dual technology sensors. The sensor works like sonar on a submarine, transmitting radar signals that "ping" the coverage area, then bounce back to the sensor on the same path. Objects that are out of the covered range are ignored. The sensor determines the attributes of an object by calculating its size and distance from the sensor. Range Settings 9, 18, 27, 35 feet
