still experimenting...didn't realize that the unit I purchased was a potential battery hog and am hopeful that it was just a bad batch of batteries the first time as they only lasted two weeks.....had to call and request more batteries so we can test out another set to see if that is the problem or not, but up until that issue arose, it worked flawlessly.....

The systems works but the alert given by the system is very irritating. It has a lot of static and the alert itself is irritating. Is there a way to install a tone or group of tones to signal a hit on the system rather than the voice?

4 mile metal driveway alert

easy to install and operate. Set up instructions were very easy to follow and understand. My wife and I cannot see the end of our driveway, so this system gives us a warning when a vehicle is approaching.
