Chamberlain® Wireless Motion Alert Systems

Chamberlain® Wireless Motion Alert Systems detect motion and alert you when a pedestrian or vehicle approaches your home or property. The weather-resistant motion sensors feature an adjustable sensitivity control to prevent false alarms from small animals.

Each system has up to 900 feet of range, long battery life, and can be easily installed practically anywhere that demands notification or protection.

Ideal for driveways, garages, sheds, business fronts, or even back entrances. The systems can also be expanded to help protect your property even further.
