Security Motion Detectors

PIR (Pyro-Electric Infra-Red) Security Detector

PIR sensors or Motion detectors/sensors are an extremely valuable device for detecting the presence of a moving body. They are extremely effective in enhancing home security systems when installed strategically in entrance points of homes, offices and business premises. We stock quality security motion detectors from leading brands including: Bosch, Ness Security, Hills Reliance, Paradox Security and Roiscok

How do PIR Sensor Work?

PIR stands for Passive Infra-Red The “motion sensing” feature in security systems is a passive system that detects infrared energy, therefore are known as PIR (passive infrared) detectors or pyroelectric sensors. They must be interrupted by a passing person in order to ‘detect’ that person, the PIR is simply sensitive to the infrared energy emitted by every living thing. When an intruder breaks into a home and walks into the detector’s field of vision, the detector “sees” a sharp increase in infrared energy. The ability of a PIR sensor to reliably distinguish moving bodies from other objects, as well as from stationary bodies makes them an ideal addition to any home security system. Its basic mode of operation is to detect the difference in heat signature between two ‘segments’ in its field of view. To avoid triggering upon sensing normal temperature variations or disturbances in airflow, a dual-element PIR sensor connects two elements in pairs these are known as Dual Detectors. When the two inverted elements in the Dual detectors are exposed to the same infrared radiation level, they cancel each other out, generating a zero-output signal as a result. This means that the detected body will have to move into or between the two elements’ field of view to cause the sensor to generate an output signal. Dual- or quad-element security sensors are able to reject false detections accurately and effectively.
