I was fortunate enough to grow up in a time and neighborhood where security was not an issue. We didn't even lock the doors when we would go on vacation for a week. I actually remember once returning home to discover we didn't even close the side door. I didn't get in trouble for the risk of theft, but for the rain water I had to clean up. Those days are long gone.

        Before we get into the obvious, lets talk about common sense. Some simple steps can be taken to help prevent unwanted intruders. These steps should be adhered to regardless of implementation of a security system.

a Don't skimp on the quality of your locks and make sure your entry doors have reinforced strike plates. these are the metal plates near the mechanisms of the locking system.

 a Keep your garage door closed and use it...If you typically park in the public view, it's obvious when you're not at home.

a For your exterior lighting, use motion sensor fixtures instead of constant lights that advertise no one is at home - and keep them on even when you're home. The activation range of a motion sensor light fixture can be adjusted to avoid repetitive tripping by pets.

a Avoid overgrowth of shrubbery and vegetation. Don't provide a place for an intruder to hide during his efforts to enter your home.

a Install window stops for each of your double or single hung windows. An 8" opening is more than enough to allow adequate "fresh air" flow in the spring or fall seasons.         

        Here are some things to consider about an Electronic Security Systems. First of all they need power. A battery back up system is a must. Secondly, these systems need a means to communicate. The typical system sends a packet of information to monitoring companies. If you're using a wired reporting system, have a separate phone line with a separate entry point installed. Most utility companies will completely conceal the entry of a dedicated security line (this will avoid someone cutting the line). If you're using a wireless reporting system, make sure your system has a "rolling Code" cycle. This prevents most electronic blocking by professional intruders. 

        How does a Home Security System help in addition to the obvious?, Insurance. Since all insurance companies are interested in lessening claims, they are willing to grant meaningful discounts to costumers that enhance their home security. Each insurance company has its own standards and requirements regarding alarm systems. Simple logic implies that a more sophisticated and expensive alarm will do a better job protecting your house, therefore have a better impact on your insurance premiums.
