Dakota Alert Driveway Monitor With this wireless driveway motion alert system you'll know when someone is coming up the driveway. The weatherproof transmitter is engineered for year-round outdoor use and projects a passive infrared beam across the driveway that will sense motion of people or vehicles up to 80 ft. away. You program the receiver in your home to sound one of four tones when the beam is crossed. You control the volume, tone style and duration of the sound. The sensor operates on a 9-volt battery (not included) and the receiver plugs into a home wall outlet. (Maximum range is 600 ft.) Wireless Probe Alert This is a very effective tool for detection of vehicles only. The probe is buried parallel to the driveway and will detect any vehicle passing within 10-12 ft. Powered by a 9-volt battery (not included), the unit comes with 50 ft. of burial cable to connect the probe to a transmitter box. When the probe senses a vehicle, the transmitter activates a tone on the receiver in your home up to 600 ft. away. Because it detects only metal objects, it's ideal for areas where deer, farm animals or pedestrians could trigger false alarms from motion detection systems.
