Features
- The video amplifier extends the range of Gira door
communication systems with video function.
- It increases the volume of the incoming video signal to the
maximum permissible bus volume and outputs it at the output. In
doing so, the line attenuation from the source of the video signal
to the input of the video amplifier is compensated.
The combination housing makes three mounting types possible
- Surface-mounted (in a standard junction box).
- Flush-mounted (in a device box).
- As a DRA device (with the included DRA adapter).
Technical data
Connections
- 2-wire bus IN:
2x screw terminals
- 2-wire bus OUT:
2x screw terminals
Ambient temperature:
-25 °C to +70 °C
Dimensions in mm
- Video amplifier:
W 36
H 52
D 27
Notes
- With the video amplifier, the maximum cable length between the
door station and home station can be extended from 100 to
300 m.
- No further configuration is necessary during commissioning
because the video amplifier automatically adapts to the existing
mains supply.
Scope of supply
- A DRA adapter is included.

Features
- The video distributor is an active component for line adjustment
of the video signal.
- The video distributor distributes the video signal of the door
stations, DCS-camera gateways, and DCS-IP gateways to the
home stations.
- The video distributor is required when the cable routing to the
video components of the Gira door communication system is
carried out as a branch line.
- The video distributor ensures the proper terminating resistance to
prevent possible reflections of the individual branches and the
resulting picture disturbances.
The combination housing makes three mounting types possible
- Surface-mounted (in a standard junction box).
- Flush-mounted (in a device box).
- As a DRA device (with the included DRA adapter).

Notes
- The video distributor is cascadable. A total of up to 15 video
distributors including video multiplexers can be used in one
system.
- No further configuration is necessary during commissioning
because the video distributor automatically adapts to the existing
line network.
Scope of supply
- A DRA adapter is included.

Features
- The video multiplexer bundles the video signals of door stations,
DCS-camera gateways, and DCS-IP gateways.
- A video multiplexer can merge the video signals from three door
stations with colour cameras. Using two video multiplexers, the
video signals from up to 5 door stations can be merged.
The combination housing makes three mounting types possible
- Surface-mounted (in a standard junction box).
- Flush-mounted (in a device box).
- As a DRA device (with the included DRA adapter).
