This wireless driveway alarm uses 50' of direct burial wire and a probe to send a signal alerting you to incoming traffic. Perfect where large animals could cause false signals with a motion detecting system. Detects vehicles passing by within 10-12'. Receiver plugs into any standard wall outlet and is free standing or wall mounted. Choose from one of four different tones to alert you. Add additional vehicle probe sensors (available separately) and easily monitor up to four zones. Each transmitter can be programmed to sound a different tone.
