Whether you’re securing a small business, large commercial property or high-security facility, you need reliable motion detectors that offer instant responses to intruders. Bosch has a long history of patented, award winning performance in the field of intrusion alarm solutions. Our products are extremely reliable providing best-in-class catch performance, while virtually eliminating false alarms. In addition our motion detectors are easy to install and built to last reducing installation and maintenance costs. The more critical the application, the more sensitivity and coverage you need from your motion detector. For maximum flexibility, Bosch offers a choice of PIR and TriTech motion detectors that suit different application requirements. PIR detectors sense movements in an area by using passive infrared technology (PIR), which sees infrared energy emitted by body heat. TriTech detectors use a combination of PIR, microwave Doppler radar technologies and advanced electronic signal processing. Only when both these sensor technologies are activated simultaneously and signals meet the requirements of the processing, an alarm will be triggered. The advanced signal processing algorithm, intelligently analyzes motion for an almost instant response to intruders while knowing when to ignore false alarm triggers under a variety of environmental conditions.
