A wireless driveway alarm is fast and easy to install while providing reliable protection and notification for home and business. Compared with traditional wired alert systems, a wireless driveway alarm can be installed much more quickly and for a lower cost. With a wireless system for your driveway, the sensor and transmitter are battery or solar powered while the receiver can plug in for power at the house, shop or store. Most of these wire free systems can be expanded by adding additional sensors and transmitters so you can cover other perimeter areas, customer drive-thru and pick-up points.
