Someone wishing to break into a home will look for a place that they can enter without being visible to neighbors or onlookers. If you have a lot of trees or shrubs surrounding your exterior doors and windows this can provide that ideal place to hide from view so you may want to make these areas a little less covered. Placing a fence around your property can also work to deter an intruder but be sure this doesn’t also provide a good place to hide.
Lights are a good way to deter a burglar. Motion sensor lighting that is installed on every side of a home’s exterior should cover all areas of the property and prevent anyone from coming close to the home to do so unnoticed. You should also leave a few lights on indoors if you are going to be away.
What condition are your windows and doors in? Ideally, they should be of solid, good quality construction and maintained well. If you feel the need to increase your windows security you may want to try installing heavy-duty wire screens or window bars (just be sure that the home's occupants could escape the home easily in the event of an emergency).
Many homes have sliding doors. If your home has them you will want to make sure there are locks on both the top and bottom of each door. An extra and simple security measure to take is to place a piece of wood the size of a cut of broom handle into the door's tracks which will stop it from opening.
Why not check over your home and see whether it can be made more unappealing to a would-be intruder?
