This spherical sensor blends into any environment, keeping a low profile while providing state-of-the-art optics. An advanced spherical lens made out of patented materials provides white light immunity. The optic pattern includes look-down (creep) zone protection using a mirror and curtain zones with a unique snap-in curtain mask.
The internal digital microcontroller with fast memory provides superior motion analysis for catch performance and false alarm immunity with environmental thermal compensation.
The PYR-2021 features jumper selectable LED operation, sensitivity, as well as cover and back tamper detection.
