This simple, inexpensive wireless motion alert will notify you if a car or person passes by the transmitter. Simply place the transmitter near the entrance to your driveway and any anything passing by the transmitter will cause the receiver to sound an 80 dB alarm. The Driveway Patrol alarm system has a whopping 400-foot range and is battery operated, making it easily portable, allowing you to use it to guard almost anything. Business owners can monitor a back entrance to their store. Parents can monitor their home for children that may sneak out at night. The Driveway Patrol motion sensor requires one 9-volt and three C size batteries, not included.
