The Wireless Driveway Monitor sends a wireless signal to your home to alert you when an unannounced vehicle enters your driveway. Movement of any large metallic (iron or steel) object close to the driveway sensor will transmit a signal to the included 4-Channel Voice Receiver, causing the receiver to sound a programmable voice message. The receiver offers ten tones/tunes and 53 selectable words (available in English or Spanish). Requires two “C” alkaline batteries (not included).
People, animals and shadows will not trigger the driveway sensor. The sensor may be placed up to 1000 feet (line of sight) from the receiver in your home. Additional sensors may be required for driveways exceeding 12 feet or to monitor an additional driveway.
