FAQ

Possible causes
The color saturation
control of the indoor
station is set to a mini-
mum.
The transmission level of
the video BUS is too low.
The light intensity does
not reach the minimum
value of 10 lux. Thus, the
camera switches over to
black and white.
The color saturation
control of the video in-
door station is too high.
The brightness control is
turned on too much
The level of the video
signal is too high.
The matching resistor at
the end of the strand is
not inserted.
The level of the video
signal is not high enough.
Our suggested solution
Adjust the contrast or color satura-
tion control.
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 camera module of the front-
door station is very insensitive to
light. Please arrange for a suffi-
cient illumination or use external
cameras.
Reduce the color saturation.
Reduce the brightness.
.
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).
Please place the matching resis-
tor.
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.)
