This Wireless Motion Alert Sensor is an add-on to our Chamberlain Wireless Motion Alert System. Add an additional level of security by adding another Sensor to your array. These sensors are specifically constructed to detect the movement of people and vehicles, while allowing small animals to pass through undetected. This means that you won't receive a ton of false alarms as squirrels and chipmunks walk past your sensor, keeping you more secure and sure of your alarm system. The best part is that it's completely wireless. You don't need to pay an electrician hundreds, or possibly thousands of dollars to set this up for you. You can do it all yourself. It's foolproof.
