What Is an Infrared Motion Detector?

0

An infrared motion detector uses infrared sensing to detect motion in a given area. This type of detector is often used as part of a larger security system, typically including the detection as a way of triggering alarms that indicate a potential issue to security or emergency services. The use of infrared technology usually allows such a detector to only pick up on heat and therefore more easily ignore non-living motion. An infrared motion detector can also be set to only pick up on certain levels of heat, making it possible to ignore small animals.
