Driveway Patrol Security Alarm System

Product Description
Driveway Patrol Security Alarm System is an infrared sensor that alerts you when someone crosses its path.
The Driveway Patrol will alert you if a car or person passes by the transmitter. Simply place the transmitter near the entrance to your driveway, anything passing by the transmitter will cause the receiver to sound a pleasant chime. The transmitter can also be placed by the front door to alert you if small children (or big children at night!) try to leave the house.
Business owners can place the unit by the front door and be alerted when customers enter the store while working in the back. The Driveway Patrol installs in seconds - just place the transmitter outside and the receiver inside. The Driveway Patrol uses wireless technology so the transmitter can be placed up to 400 feet away from the receiver. The transmitter uses Passive Infra-Red (PIR) to detect motion.
The transmitter measures in at 4 1/2 inches x 2 1/2 inches x 2 1/2 inches. The receiver measures in at 4 11/16 inches x 3 1/2 inches x 1 1/2 inches. The transmitter requires 1 9-volt battery (not included). The receiver requires either 3 C batteries (not included) or a 4.5 volt adapter (not included).
