Bosch Blue Line Gen2 Quad PIR Motion Detector - ISC-BPQ2-W12

Each sensor processes signals separately. Both must activate to generate an alarm signal.

This feature improves false alarm immunity relative to a standard PIR, because false alarm sources such as noise spikes and small animals are ignored.

Quad detectors also provide superior catch performance versus a standard PIR or dual-technology detector. They are 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.
