FAQ
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.
