FAQ
Error pattern
Possible cause
Our suggested solution
The video image is black and
white.
The color saturation control of the
indoor station is set to a minimum.
Adjust the contrast or color satura-
tion control.
The transmission level of the vid-
eo BUS is too low.
At many components of the video
BUS (e.g. FVY) the transmission
level can be adjusted.
Please see the product information
of the active transmission compo-
nents.
The light intensity does not reach
the minimum value of 10 lux.
Thus, the camera switches over
to black and white.
The camera module of the front-
door station is very insensitive to
light. Please arrange for a sufficient
illumination or use external camer-
as.
The colours of the video image
are too bright or the image in
general is too bright.
The color intensity control is
turned too high.
Reduce the color intensity.
The brightness control is turned
too high.
Reduce the brightness.
The level of the video signal is too
high.
Reduce the level of the video BUS
(This only works, if the matching
resistor is placed correctly at the
video indoor station).
The matching resistor at the end
of the strand is not plugged.
Please observe:
The colours of the video image
are without contrast.
The level of the video signal is not
high enough.
The connection line between two
active video components was ex-
ceeded impermissible.
Please check if the number of al-
lowable video indoor stations per
strand was not exceeded.
In one building block with mul-
tiple indoor stations, only one
indoor station shows black
lines on the video image.
Image interferences due to transi-
tion resistance.
The P-wire is not connected correct-
ly.
The connection contacts are not
completely fixed.
Image interferences due to near
disturbing sources such as exter-
nal power supplies or other elec-
tric appliances, which are not
shielded.
Relocate the video distributor or any
other passive assembly package.
Distortion due to compensation
currents caused by potential dif-
ferences.
Please check the line installation
and try to install active components
on one potential.
Integrate a coupling element into
the video BUS to galvanically iso-
late it.
This accessory you can order from
TCS technical distribution.
