Optex LX-402 Weatherproof Outdoor Passive Infrared Motion Detector

Connect a motion sensor to your security system for immediate, accurate alerts when an intruder is detected on your property. With its 40' x 50' 120-degree wide angle capture area, the 40 X 50 Outdoor PIR w/Double Conductive Shield will keep an eye on a broad area of your property when your security system is armed, and with its built-in double-conductive shield, it won't be falsely triggered by direct sunlight. Use the included masking strips to create a specific detection pattern, if desired. In this way, the 40 X 50 Outdoor PIR w/Double Conductive Shield can be used as a pet-immune motion detector or can capture motion only in specific spots. Sensitivity can also be set at high, medium, or low. This motion detector has an adjustable day/night mode that you can set depending on the ambient brightness of the surrounding area. Set the sensor to function 24 hours a day, only during certain hours, or only after dark.
