Device description
The DCS-camera-gateway integrates a common
analogue camera into the Gira door communication
system. The connection of the external camera is
made with screw terminals. An adapter cable is
included for cameras with BNC connection. A
camera gateway and own power supply are required
for each external camera.
The camera gateway can be operated with or wit-
hout an assigned door station.
• Function with assigned audio door station :
The external camera is assigned to an audio door
station and functions as a system camera (i.e. au-
tomatically activated with a door call).
• Function without assigned door station:
The camera gateway is not assigned to a door sta-
tion. In this case the camera image can only be
switched on manually via home stations with vi-
deo function.
Installation
The combination housing of the DCS-camera-gate-
way makes various installation types possible:
Without DRA adapter
• Surface-mounted (e.g. in a surface-mounted
junction box)
• Flush-mounted
(in a deep flush-mounted device box)
With DRA adapter
The DCS-camera-gateway can be installed with the
included DRA adapter on a top-hat rail in a distribu-
tion.
The DRA adapter accepts a BNC plug connection.
When installing the camera gateway in a distribution
the BNC plug connection must be inserted here. The
cable can be fixed with cable ties through openings
in the DRA adapter.
The installation height of the camera gateway in the
distribution varies depending on the plug-in direc-
tion. This enables both flush installation and instal-
lation below the protective cover.

plate (1) in the DRA adapter and then snap in the
camera gateway.

Connection
BUS IN
Connection for the incoming video signal from door
stations with video function or from further camera
gateways.
Because the video signal in the camera gateway is
only routed in one direction from BUS IN to
BUS Out, all door stations with video function or
further camera gateways must be connected via the
Gira 2-wire bus to BUS IN.
BUS OUT
Connection of the camera gateway to the video con-
trol device via the Gira 2-wire bus. The video signal
of the external camera is transmitted via BUS OUT.

2-way switch
1
The power supply or activation input of the camera
can be switched via the 2-way switch relay connec-
tions.
The relay is operated with a door call from the assi-
gned door station. The delay time of the relay is
30 s, i.e. 30 s after the conversation is ended or after
switching to another camera the relay reverts to the
rest position.
Backing terminals
The backing terminals insulated from each other can
be used for through-wiring of the camera power
supply:
