Outdoor Passive Infrared Detector
IFR150XT Infratronic IFR150XT long-range Passive Infrared Detector (PIR) has been developed for detection of intruders up to 150 meters. Can be used when the installation of traditional active infrared beams is difficult or impossible. Moreover the area protected cannot be identified by an intruder due to the passive operation of the unit. Operation The IFR150XT is a passive device designed to detect any intruder by his movement due to the infrared contrast against the background. Two curtains sensing areas provide the alarm only when they detect infrared radiation emitted by a human body entering in the first curtain and leaving the second one. The detection algorithm eliminates slow temperature changes and avoid nuisance alarm caused by small animals, flying birds and moving vegetation. The IFR150XT provides a tamper and mercury switch which is activated whenever the device is opened or moved. This allows the security guards to identify any attempt to disable the IFR150XT or alerts them if the unit is out of service due to maintenance work. Since the IFR150XT only react to infrared radiation, they can be used during day&night as well as under changing climatic conditions such as fog, rain and snow. For the installation, a robust IP65 weatherproof aluminium housing is supplied with his bracket. An easy optical alignment is provided through a built-in view finder. A precise optical protection can be obtained due to the accurately defined sensing curtain. The connection cables are completely invisible and equipped with concealed cable channel inside the bracket. Application Usefull for the protection of large buildings and long walls as well as combined with CCTV systems and Video Motion Detectors (VMD).
