Digital double-layer detection entails the requirement that both upper and lower detection areas must be crossed simultaneously to trigger an alarm. The two internal PIR sensors autonomously analyse the detection, allowing the filtration of misleading coincidences of events. This technology is highly effective in virtually eliminating detections triggered by smaller animals within the premises. The Mobeye CMVXI-R is enhanced with a digitally enhanced signal recognition logic known as SMDA. SMDA plays a crucial role in improving immunity against various noise factors, including climate changes and vegetation sways.
