The Streetwise Driveway Alert is a wireless notification system that will alert you if a car or person enters or exits your driveway. Simply place the transmitter near the entrance to your driveway and the receiver inside your home up to 400 feet away from the transmitter. A person or car passing within 26 feet of the transmitter will cause the receiver to sound either an alarm or a pleasant chime. The transmitter can also be placed by your front door to alert you if small children (or big children at night!) try to leave the house. Business owners can be alerted when customers enter the store while they are working in the back. The adjustable volume ensures you will never miss a customer.
