LiftMaster Perimeter Alert Systems
It’s a hard thing when you’re suddenly caught off guard by someone, or something, entering your surroundings. The reality is that there is no reason to be caught off guard; while you’re on own property; when you purchase and install one of LiftMaster’s perimeter alert systems. With these systems you will be alerted the moment a pedestrian, or vehicle, approaches your property. Best of all, with up-to a half mile range and long battery life, you can easily install it anywhere on your property – driveway, shed, backyard, business fronts or walkway.
