Passive Infrared Motion Detectors- These detectors are called PIR detectors. The technology they utilize is "passive infrared". The device is mounted on a wall or in the corner of a room. It sends invisible fingers out into the covered area in one or two layers.
When thinking about your house security situation, no doubt that you have thought about home alarms, cameras and even a safe room. These are all neat methods to stop crime, particularly theft and home invasions.
