AAS Wireless Passive Infrared Motion Detector

Passive infrared (PIR) sensor technology provides one of the most reliable and cost effective methods for protecting spaces in home or office. PIR detectors trip an alarm when sensory changes in infrared energy levels caused when an intruder moves about the protected area are detected sending an alarm signal to the Main Digital Keypad/Auto-Dialer unit. PIR's emit no energy of their own. These motion sensors merely "see" infrared images. Built-in smart technology senses both heat and movement. Senses work in light or dark conditions 24 hours a day

Motion sensors - motion sensors usually detect motion based on body heat in a 90 degree angle up to 45 feet away. The optimal place to install your motion sensor is in a corner, so the 90 degrees of coverage run along each wall, effectively covering the maximum amount of space. Additionally, it helps to install them at a height of 5 feet or lower so they can detect ground motion as well. Alternatively, you can install them between the wall and ceiling, pointing downwards at an angle to cover the room (this type of setup will typically involve screws, or a semi-permanent installation).
