Dual technology sensors
Dual-technology volumetric sensors (Piramid) integrate a proprietary microwave design (termed Doppler effect) with passive infrared technology. The microwave technology detects the motion of the intruder and the infrared detects a change in IR radiation as the intruder moves through the field of detection.
Both technologies need to be simultaneously activated to create an intrusion alarm.
