GE Driveway Monitor

"Don't be surprised by visitors, welcome or not. The Driveway Monitor keeps tabs on your driveway, wirelessly transmitting an alert to the receiver in your house, up to 400 ft away. Visitors are announced with a chime and flashing light. The battery-powered sensor installs in seconds with its stake mount. Magnetic field technology only recognizes large metal objects, avoiding false alarms from pets or pedestrians. Sensor and receiver each use 2 AA batteries, included.
