A home intercommunication system can be much more than just an easy way to call members of the family to dinner or to summon someone for a phone call. At a relatively modest cost, you can have a paging system that includes a radio to provide music throughout the house. Moreover, you can enhance home security with a front-door speaker that allows you to talk with a visitor before opening the door.

Installing a home intercom system requires only moderate carpentry ability as well as some simple wiring tasks. Some newer intercom systems use battery-powered wireless modules to extend the system without running wires in walls.
