The motion sensor is a passive infrared device that senses the temperature change in a certain spot of the room. It actually sees body heat given off by a human body as it crosses its field of view. This technology has been used for over 20 years and is probably one of the most reliable methods possible to detect intruders. The SAW PIR is manufactured to detect movement inside an enclosed place.
