The place to start in implementing home security measures is a security survey done by a professional. Usually a local police force will send a security expert out to a home to walk the house and grounds with the owner. If this service is not available in your community, they may provide you with pamphlets or other materials that will allow you to do your own survey.
Several books are on the market as well.
Also, if you plan to have a professional install an alarm system, the company will often perform the survey Be careful, because they might have a hidden agenda to sell you a more expensive security system than you need. To really do the survey correctly, you need to think like a burglar. Almost all home security is focused around these two facts, the mainstays in all burglary work. A walk around your home, preferably with a professional, should quickly point out to you your weaknesses in home security. If you are like most of us, locking yourself out from time to time, you probably already know these points of vulnerability You probably know as well just how easy it really is to break into most homes.
