I agree with the lights to go to and fro, but it's a waste for unoccupied areas. My brother is in the security camera business, IR cameras have been shown to be better in that they can be triggered to alert someone without revealing their presence so that authorities can be called in to catch them in the act. When you have cameras and lights on, the thieves take out one or the other and if nobody is watching at that instance, it goes unnoticed for too long. Lately thieves have been stealing the cameras too! He has a video of the guy coming right up to the camera, smiling at the lens, then it goes dark. Sure, they know what he looks like, he looks like a million other scruffy bums. big deal.
He just sent me this one too. Notice that the lights are on...
