Using the DCS IP gateway, additional systems from other manufacturers and functions can be connected to the network via the HomeServer. The door communication system can be integrated via a plug-in, for example. Everything can be easily controlled via the Gira Interface and audio-visual door communication is enabled via the Gira Control Clients, or using a PC, tablet, or smartphone. Systems from other manufacturers such as the Revox multiroom system, Miele@home, Dornbracht Ambiance, etc. can be universally controlled via the HomeServer.
