An intercom system can be tied in to work with your whole-house audio system. By picking up any telephone and with a push of a few buttons, you can speak through speakers set-up in various rooms around the house. When communicating with someone at the front door a push of a key on the phone can unlock the door.

Traditional intercom systems are also available and can be installed with push-buttons and speakers in each room with a master control panel located in a central area of the house. These traditional intercom systems also feature music playing capabilities with AM/FM. Options with intercom systems also include a CD player or other external audio sources are also available on some units.
