Network-based SIP door communication systems enable cross-device audio, video and entry functions in buildings with multiple residents. In combination with the Gira F1, this guarantees secure segmentation of the building network and the private network used in the individual residential units. Only the necessary video door call for the door station is enabled and forwarded to the home station, such as the Gira G1, within the private network. All other access points and IP connections remain blocked, thereby reliably protecting private networks in the building from unauthorised access.
