PrecisionLine dual technology motion sensors offer easy solutions for your most challenging residential, pet or commercial applications. Using a sophisticated combination of precision controlled microwave and passive infrared (PIR) technologies, these sensors give you total Coverage-on-Demand. PrecisionLine dual technology motion sensors reduce installation and training time since the installer is not required to make any complicated adjustments to the sensor. 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---a 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. This allows it to ignore pets such as cats and dogs without any loss of detection. For high security installations that require quicker detection, radar-only mode is available. Designed for flexibility, PrecisionLine sensors are the ideal solution for a variety of challenging commercial and residential applications.
