FAQ
Error pattern
Possible causes
Our suggested solution
The video image is black and
white.
The color saturation control of the
indoor station is set to minimum.
Adjust the contrast resp. color
saturation control.
The transmission level of the video
BUS is too low.
The transmission level can be
readjusted at many components of
the video BUS (e.g. FVY).
Please check it in the product
information of the active transmis-
sion components.
The light intensity of at least 10 lux
is not reached. Thus the camera
switches to black/white.
The camera modules of the front-
door stations are very photosensi-
tive. Please ensure a sufficient
illumination or use external cam-
eras.
The colors at the video monitor
of the indoor station are too
bright or the image in total is
too bright.
The color saturation control at the
station is set too high.
Turn down the color saturation
control.
The brightness control of the station
is set too high.
Turn down the brightness control
at the station.
The level of the video signal is too
high.
Turn down the level of the video
BUS (e.g. rotary switch at the
board of the camera). Is only
working, if the terminating resis-
tance at the station or active ex-
tended functions (e.g. FVY) is set
correctly.
The terminating resistor at the end
of the strand is not plugged.
Please plug the terminating resis-
tor.
Colors on the monitor are
without contrast.
The video signal level is not suffi-
ciently high enough.
The connection lines of a surface-
mounted camera were extended
incorrectly.
The line length between two active
video components was impermiss-
ibly exceeded.
Level reduction can be compen-
sated to some extend by rotary
switches at active video compo-
nents (see product information of
the components).
Please check if the number of
allowable video indoor stations per
strand has not been exceeded.
The terminating resistors at the
video distributors or video switches
with loop through signals are not
installed properly.
Remove the terminating resistors
of the involved components. Only
the last video component of the
strand requires a terminating re-
sistor
