Optex Passive Infrared & Microwave Combination Detector

Optex provides unprecedented reliability in detection by integrating state of the art microwave and PIR technologies. This sensor combination detector incorporates a patented "quad zone logic" which requires detection across multiple zones before an alarm is triggered. As a result of this technology, your guarantee false alarm protection from 100 pound pets/animals and immunity from other smaller disturbances such as heating vents and movement from curtains. Its spherical lens design ensures sharp, precise detection zones without distortion for increased reliability. This sensor introduces a built in "anti-crosstalk system," preventing interference from matching microwave frequencies in a single area.
