Really surprised that no one else is as outraged as I am with the fact that this motion detector is of such poor quality. I decided to dust off my old powerhouse SP554 this was a much better design at least in the 2 movement mode in over 6 years I never got a false alarm and no way could you take more then a couple steps with out it picking you up only problem with it was the relatively short range and the fact that the battery life was only good for about 8 months even just left in a vacant house the batteries would die in about 9 months, but it worked!!! Working on a new hardwired system with some wireless components so by the time the batteries give out I should have my new system up and running.
