With the Electro Guard Watch Driveway Alarm sensor in your driveway, a car approaches and the reciever alarms.
Driveway alarm and reciever can be up to 400 feet away from each other.
Use a 9v battery on the transmitter and 2 x AA on the receiver.
Having a wireless driveway alarm monitor your driveway is fun and useful.
But the value goes way above the use.
Simply having visible security systems like motion sensors could act as a deterent making intruders go elsewhere.
Even if you don`t need a visitor announcement system and leave your Driveway Alarm off.
