The WPA-3000 is an extremely reliable driveway alarm that is used to detect vehicles only. The transmitter operates on one 9-volt battery and has 50' of direct burial wire connecting the probe to the exterior case. The probe is buried parallel to the driveway, and will detect vehicles passing by within approximately 10-12 feet. The direct burial cable can be run to a tree or post nearby, where the transmitter box is located. When a vehicle drives by, the transmitter will send a signal to the WR-3000 receiver up to 3,000 feet away*.
