Keep track of vehicles entering or exiting your property with our FM231 wireless driveway alarm system. The system monitors and alerts you when someone enters your driveway, no matter the length or type of driveway. With a 400 ft range and an electromagnetic motion sensor that only detects vehicles, this driveway alert system is perfect for homes or businesses, allowing you to keep a pulse on who is coming in and out of your driveway. Increase the long-range wireless system with additional driveway vehicle sensors that can be programmed to automatically open your gate for exiting guest without using a remote.
