Intercom External Units
Intercom external units permit audio and video communication through the intercom system. Old intercom external units offered audio communication transmitted via the intercom panel to the audio intercom receiver, for door unlocking. Present intercom external units provide video communication in color or black and white for complete access control identification of the user.
