Although no system makes your home completely burglar-proof, a home security system can reduce your chances of being burglarized and give you peace of mind. The Better Business Bureau advises consumers to investigate the purchase of a home security system with the same care as they would any other major purchase.
Security systems can either be wireless or wired.
Wireless systems use battery powered transmitters to connect the various system components. They can be bought at hardware stores and installed by the homeowner. Wireless systems have the advantage of low cost, simple operation, and portability to a new home. However, most do not give the option of connecting to a network that will alert police. With a wired alarm, the system components are permanently connected by wires in the walls.
