Gira G1 SIP client

Large door communication systems

The network-based SIP protocol (session initiation protocol) enables a communication link to be established between several devices. SIP is established as a technical communication standard in the field of door communication, and is based on the server/client architecture. Multiconversation mode and concierge function are frequently requested functions offered by this standard.

The Gira G1 as a SIP client

When large systems with more than 62 video devices and multiconversation mode are required, the Gira G1 can be used as a SIP client. Designed to integrate seemlessly with third-party IP door stations, the Gira G1 SIP client currently supports systems from providers, including Comelit, Schüco, and TCS. The Gira G1’s double function means that it can be used as an SIP home station and a KNX interface.

Benefit for users: they only have a single display on the wall.
