Bosch ISM-BLQ1 Motion Detector

The Bosch ISM-BLQ1 Quad detectors combine an unsurpassed level of catch performance with the highest level of false alarm immunity, making them particularly well suited for challenging installation situations; for example, cases where cross catch of intruders cannot be guaranteed or where intruders are able to cross the detection pattern very quickly. First Step Processing (FSP) almost instantly responds to human targets without producing false alarms from other sources. FSP adjusts the detector's sensitivity based on signal amplitude, polarity, slope, and timing.
