Our Driveway Patrol Alarm has endless possibilities for securing your property. When the transmitter senses motion, it sends a signal to the receiver, alerting you with a non-offensive 80db alarm. The Driveway Patrol has an amazing 400-foot range and is battery operated, making it easily portable. The uses for this alarm are endless: use it as a door alarm at your business, or keeping track of your children's comings and goings. Requires one 9 volt and three "C" size batteries, not included.
