CCTV view of burglar breaking in to home through window with crowbar Not everyone is able to install security cameras that cover every single part of the home, which is why you should focus on the most important points of entry first. 79% of break-ins happen via either the front door, a first floor window, or the back door. These are the most vulnerable areas, and statistically the most likely to be the point of entry. If you install cameras that cover all of these areas, you will be able not only to monitor what is happening, but provide evidence in the event that someone does burglarize – or attempts to burglarize – your home.
