Intercom design

To understand the operating principle of the intercom and the features of independent connection and configuration, it is necessary to clarify the internal structure of the system.

The outer panel has different designs: with dialing buttons, with a reading platform that processes codes from keys or cards, with backlighting and even visual support. The last modification is not too common and is found in particularly protected facilities.
