LiftMaster Perimeter Alert System

Never be caught off guard again! LiftMaster Perimeter 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 alerts from small animals. Each system has up to 1/2 mile of range and long battery life. And can be easily installed practically anywhere that demands notification or protection - driveways, garages, sheds, business fronts, or even back entrances. The system can also be expanded to help protect your property even further.
