Possible causes
Our suggested solution
The video image is
black and white.
The color saturation
control of the indoor
station is set to a mini-
mum.
Adjust the contrast or color satura-
tion control.
The transmission level of
the video BUS is too low.
At many components of the video
BUS (e.g. FVY) the transmission
level can be adjusted.
Please see the product infor-
mation of the active transmission
components.
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 suffi-
cient illumination or use external
cameras.
The colors of the
video image are too
bright or the image in
general is too bright.
The color saturation
control of the video in-
door station is too high.
Reduce the color saturation.
The brightness control is
turned on too much
.
Reduce the brightness.
The level of the video
signal is too high.
Reduce the level of the video bus
(e.g. rotary control on the camera
board). This only works, if the bus
termination at the video indoor
station or at the active extended
function is inserted correctly (e.g.
FVY).
The matching resistor at
the end of the strand is
not inserted.
Please place the matching resis-
tor.
Colors of the video
image are without
contrast.
The level of the video
signal is not high enough.
The connection line of a surface-
mounted camera was inadmissibly
extended.
The cable length between two
active video components was
inadmissibly exceeded.
Video level loss can be regulated
via the rotary control in active
video components (see product
information of the components.)
