The ADS digital video and audio door-entry system is simple to install, as it does not use call wires for each apartment.

The ADS amplifier includes Voice Synthesizer as standard. A message is reproduced when the lockrelease is activated: "The door is opened, please close the door behind you".

The ADS telephones and monitors function by means of a microprocesser and must be programmed with the number of corresponding home.

Communication is private. During communication no other tenant can hear the conversation.
