Motion Detectors can be the first line of defense to keep a burglar out of your house.
Just think about how and where someone could get into your house without much trouble.
Are your doors and windows really secure including the upstairs windows? Do you have an outside entrance to your basement What about your garage -- is it detached or is it part our your house? All of these are potential entrances for a burglar.
So you ask "How, then can I prevent a burglar from getting into my home?"
