INTERCOM

An intercom or intercommunication device, talk back or door phone is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network.

Intercoms are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to public address loudspeaker systems, walkie talkies, telephones, and to other intercom systems. Some intercom systems incorporate control of devices such as signal lights and door latches.

We also provide Audio-video intercoms allowing you to see who is at the door before you decide to open it or not open.
