The Passive-Infrared Senor detects movement within a specific area by sensing the infrared energy emitted from a body as it moves across the sensor’s field of view, causing temperature change in the sensor’s zones. Use the motion sensor to protect locations where door/window sensors are impractical or not needed. Motion sensors also provide backup protection for door/window sensors.

 

This sensor is indoor / outdoor but needs to be protected from nature. A masking kit is provided to block portions of coverage area. There is a three minute transmitter lockout time after an alarm that helps extend battery life. This sensor covers a more square area of 35 foot X 40 foot area. This infrared sensor will detect animals.

 

We offer a simlar one that will not detect a 40lb animal. We do also offer a more distant infrared sensor that goes up to 50 feet.
