I have several lights that are dusk to dawn and a motion sensor double flood along the driveway. I also have two signs that say "smile you're on candid camera" that you can easily see where you would ordinarily park the car at night. I was up last nite when a car came up the driveway, stopped and two guys got out and the floods came on. I just happened to be up getting a drink of waster and saw the whole thing and what was funny, was that they both looked around to see if they could see a camera and got PERFECT face pix of both of them and their license.
I believe that if you are gonna spend some money for cameras,you should get good ones. Not quite like the ones on an SR-71 that can see a golf ball on the green from 70,000 feet though.
