Most homes have as many as 15 locations that can benefit from a security camera. In the right place, it only takes one. Recently, a hapless burglar in Tampa was recorded walking around a living room picking up objects in full view of a security camera that captured his every move. Police got quick assistance from the community to identify him. The New York Times cited the number of homes that have security devices at 17 percent. Those homes can give police more to go on than others that have no picture or physical evidence of a burglary.
