My problem with this product is that it has delayed reaction. The target has to do at least 25-30 sec. Kabuki dancing in front of it for sensor to kick in. It might be good for a cable guy writing you a love letter, as one of the reviewers below describes, but even a jogger will be able to run circles around your house without ever being spotted, leave alone a car illegally parked on your driveway. Returned it for free with no problems (thank you, Amazon!) and bought more expensive Skylink HA-434TL Long Range Motion Kit - works like a song!
