ROKONET COSMos PQ Quad PIR Detector |
| A Quad PIR detector with microprocessor technology COSMoS PQ offers two dual Element Pyroelectric sensor. Microprocessor based techniques enable the detector to analyze continuously the protected area in order to identify motion. Each IR channel responds to the difference between the thermal radiation caused when an intruder crosses the protected area and the ambient thermal radiation. An alarm in initiated only when both channels operate simultaneously, thereby significantly reducing the chances of false alarm. 18 ft X 50 ft |
