New: Up to 16 intercom units  –  Client and Server mode  –  KNX integration possible

The INTERCOMMODULE allows full integration of the video door intercom into the building visualisation.


The INTERCOMMODULE establishes the connection between an IP-capable video door phone system and the building automation. Together with the EIBPORT or the CUBEVISIONMODULE it is possible to display the sound and image of a video door intercom system within the visualisation. Integrated functions for opening the door or switching on the lighting offer the usual comfort of a contemporary IP door intercom. With freely configurable KNX triggers (Art. no. 10583), you can implement many more convenience functions. For example, connect your sound system to the doorbell or receive a push notification. For use without building automation, the optionally available software CONTROL T 2 is available. With it, you can turn your Windows PC or Mac into an indoor call station for your door communication system.

The INTERCOMMODULE is intended for use in small systems and can support up to 16 door stations and 16 in-house stations.

It is also an application server for video and VoIP (Voice over IP) based on the open source software FreeSWITCH. SIP-compatible control elements can communicate with it without detours.
It is important to distinguish whether the video door station is a SIP server or a SIP client. For example, a SIP server is ABB Welcome. The ABB Welcome has an IP gateway (83342) that functions as a server to which you (the INTERCOMMODULE) must explicitly log on.
Other intercom systems such as DoorBird or 2N act as clients and therefore do not need to be explicitly configured in the INTERCOMMODULE.

The INTERCOMMODULE supports both SIP client and SIP server video door intercoms. The door stations can therefore be operated in both “client mode” and “server mode”.

Currently “Client Mode” supported video door intercoms:

DoorBird, 2N, AGFEO, Mobotix, Koch, Akuvox

Currently “Server Mode” supported video door intercoms:

ABB/Busch-Jaeger Welcome in combination with the INTERCOM IP Gateway 83342

The INTERCOMMODULE supports different SIP topologies and login procedures:

  • intercom systems without gateway with anonymous login, e.g. DoorBird, 2N
  • intercom systems without gateway with active registration, e.g. AGFEO, Mobotix
  • intercom systems with gateway, e.g. ABB Welcome.


The integration of the video door intercom into our visualisations is very easy:

  1. generate and copy token in INTERCOMMODULE
  2. Insert into the corresponding visualisation element

This establishes the connection to the outstation.


The INTERCOMMODULE is set up in only 3 steps:

  • Select and name the front-door station and enter access data
  • name internal stations and enter access data
  • assign call buttons to the in-house stations


Das INTERCOMMODULE is also available with KNX connection. In addition to the integration of door bell, door opener and lighting, the assignment of the outdoor station to an indoor station can be changed via KNX telegram. This enables, for example, the time or situation-dependent connection of the door intercom system to various in-house stations. If the connection to the home office on the ground floor is to be dialled during the day, the door call to the apartment on the first floor should be made in the evening.
