One way to combat burglaries is a home security system. Here are some answers to common questions along with tips about purchasing a home security system.

Is the system really free?

Can I do it myself?

There are DIY options out there. Buying your own equipment online can save you a considerable amount of money. You do need to find a certified monitoring company that works with DIY users.

If a monitored home security system isn't right for you be sure to take other precautions. Lock your doors and windows and trim shrubbery away from them. Install motion-sensor lights outside. Give a trusted neighbor a spare key instead of hiding it in the usual spots like under a doormat or in a "key rock."� Use a peephole or a window to check and see who's knocking before opening your door. And if you didn't call for a salesperson or contractor don't let them in.

When you take care of protecting your home you won't need to worry when "the wild rumpus" starts!
