Chamberlain CWPIR Wireless Motion Alert Add-On Sensor

The Wireless Motion Add-On Sensor with adjustable sensitivity control expands the coverage area of the Wireless Motion Alert system (sold separately) to create a safe outdoor perimeter of up to a 30-ft. radius with a single base monitor. Ideal for homes, businesses, worksites or any properties with no fencing, Chamberlain Wireless Motion Alert system can be expanded with seven additional Wireless Motion Sensors up to 1/2 mile from the base. Each sensor is weatherproof and durable with a mounting bracket and two-year battery life and covers a 120-degree area. Using passive infrared (PIR), sensors emit a unique light and sound pattern that allows the base monitor to identify which sensor has been triggered when vehicles or pedestrians approach.
