Same here using it as a reactive measure. I guess my version of having movement sensors is that most of the time someone is always home and I have live view of all of the cameras setup so any PC in the house can pull them up but they are always displayed on monitors in my living room that are mounted around my TV so anyone sitting in the living room will see if someone is messing with something. Also I have motion flood lights in front and on the side of my house over my garage so that helps with drawing attention at night.
