Device description
The colour camera is part of the Gira door communication sys-
tem and is used for the expansion of the flush-mounted outdoor
station.
The colour camera boasts the following product features:
Automatic day/night switching
The camera switches from daytime operation (colour presenta-
tion) to night mode (black and white presentation) and back
again at an ambient brightness of 1 lux. Good display results are
achieved due to the high-degree of light sensitivity in night
mode, even with poor lighting conditions (up to 0.1 lux).
The integrated white LEDs ensure an even field of view illumina-
tion in night mode.
Large range of coverage
The colour camera can be swivelled manually by 20º horizontally
and vertically during start-up. A very large field of view in the
door entry area results in conjunction with the 100° range of
coverage of the camera.
Camera heating
The integrated temperature-dependent camera heating pre-
vents condensation from forming on the camera cover due to
changing climactic conditions and thus provides a clear view.
Camera cover
The splash water-resistant cover made of impact-resistant plas-
tic can be easily replaced if damaged, e.g. through vandalism.

Selection of the installation site
The selection of the installation site and good illumination are
critical for good picture quality.
No background lighting
Do not point the camera toward strong background lighting,
such as streetlamps or yard illumination.
Prevent strong sunlight from hitting the lens.
Picture background
Avoid pointing the camera toward extremely light picture back-
grounds and backgrounds with stark contrasts.
Illumination
LEDs integrated in the camera provide even field of view illumi-
nation in the darkness.
If the entry area is equipped with additional illumination, ensure
that the light source does not shine directly into the camera lens
from the front. The best installation site of an external light
source is above the colour camera.
Installation height
The recommended installation height of the colour camera is
1.50 m. At this installation height, people with an average height
of 1.80 m are presented optimally.
The minimum installation height is 1.20 m.
i
Black and white mode in poor lighting conditions
In poor lighting conditions (< 1 lux) or with the field of view illu-
mination switched on, the colour camera provides black and
white pictures only.

Mounting
The colour camera is operated together with a flush-mounted
outdoor station:
1. Insert the 6-pole audio connection cable into a system con-
nector of the flush-mounted outdoor station.
2. Insert the 2-pole video connection cable into the video slot
of the bus coupler of the outdoor station.
3. Guide both connection cables into the flush-mounted instal-
lation box of the colour camera and insert both connection
cables into the flush-mounted insert of the colour camera.
Attention
Installation and mounting of electrical devices may only be car-
ried out by a qualified electrician.
Do not use the sealing rings included with the TX_44 frame
when installing flush-mounted inserts.
i
Bus coupler jumpers
The wire jumpers at the bus coupler of the outdoor station
between BUS and ZV are required for the operation of the
colour camera. Thus the illumination of the call push buttons at
the outdoor station cannot be switched off.
i
Colour marking on camera insert and top unit
To avoid mix-ups, the camera inserts and top units are marked
with a red dot.

4. Install the camera insert.
5. Place the bottom section of the TX_44 cover frame in place
and attach the camera top unit and the central inserts of the
outdoor station to the flush-mounted inserts.
6. Set the camera lens in the desired direction
(see "Setting range of coverage", Page 8).
7. Remove the protective film on the lens.
8. Attach the camera cover.
9. Clip on the frame top section and press in the Torx screws.
Start-up
Once you have installed all of the devices (outdoor and home
stations, video control unit etc.), you can start up the door com-
munication system.
Start-up is described in the system manual included with the
video control unit.
i
Measures for theft protection
To protect the outdoor station from theft, you can secure the
bottom section of the TX_44 frame to the wall with screws and
screw plugs.
Instead of using Torx screws, you can also use the optional Tri-
Wing screws to secure the top section of the frame.

Range of coverage of the colour camera
The CCD sensor element of the Gira colour camera has an angu-
lar coverage of 100°.
If this angular coverage is not sufficient for your installation sce-
nario, you can swivel the area to be captured by 20° in all direc-
tions.

Setting range of coverage
1. Remove (with the TX_44 frame open) the cover
from the colour camera.
2. Loosen both Torx screws to the left and right of
the camera lens.
i
Protective lens film
The protective film on the lens of the colour camera protects
the sensitive optics from scratches and soiling.
Leave this film on the lens as long as possible and avoid touch-
ing the lens directly after the protective film has been removed.
i
Do not screw the screws out completely!
When adjusting the lens carrier, it is sufficient to slightly loosen
the screws.
Do not completely unscrew the screws from their brackets.
