COMBINATION DETECTOR ENHANCED PIR / MICROWAVE
integrating PIR and microwave technology into attractive, easy-to-install units, the DX-40 provides stable and reliable detection in the most hostile of environments, where simple PIR detectors struggle to function. The PIR element incorporates Quad Zone Logic to detect the smallest temperature contrast against the background temperature, enabling it to discriminate between humans and other sources of infrared. Additionally, the microwave detector incorporates Microwave Area Shaping technology to prevent the unwanted detection of movement outside the coverage area.
