Fortress Total Security Motion Detector

The Fortress Total Security Motion Detector uses Passive Infrared technology to detect motion. These sensors can pickup motion up to 25 feet from the device. With a viewing angle of 110 degrees horizontally and 90 degrees vertically you can be assured that these sensors will detect any intruders. Communication back to the main panel can be from up to 150 feet away depending on obstructions. With built in switches to control time between triggering events, and the LED that flashes to indicate detection of motion, conserving battery power has never been easier. Fortress Total Security Motion Detectors use 2 AAA batteries.
