Wireless PIR Sensors
(5 products)
Wireless PIR sensors are a great option for easy installation, ideal for use in areas not convenient to support cabling. They work by detecting infrared light from movement by something that gives off heat, triggering the sensor to activate and create an alert if desired. A wireless PIR is typically installed as part of a wider system and often has great features such as pet friendly detection and a wide sensor range.
