This convenient battery operated driveway monitor sends a wireless signal to your home to alert you when a vehicle enters your driveway using a patented magnetometer sensor system. Movement of any large metallic (iron or steel) object having a magnetic field will cause the sensor to transmit to the receiver. (People, animals and shadows will not trigger the driveway sensor.) The sensor may be placed as far as 1000' away from the receiver in your home. Can be set to low, medium or high sensitivity levels. Includes transmitter, receiver, receiver antenna, AC adapter and mounting kit.
