The Blue Line Gen2 Quad PIR Detector uses two individual sensors that operate like two PIRs in one detector. Each sensor processes signals separately. Both must activate to generate an alarm signal. This improves false alarm immunity relative to a standard PIR, because false alarm sources such as noise spikes and small animals are ignored.
