Poor Video Signal

Determine if wiring
polarity at “Video
Connector” terminal
block is correct.
Check BNC
connector.

If still no video,
connect the camera
directly to the
monitor. Check the
video signal. If okay,
the problem is with
the interconnections.
If still no video,
contact

a Bosch

Service Center.
See rear page of
this manual for
contact
information.

_________________
Ensure video cable is
correctly matched
and terminated with
75 ohms at each end.
Make sure video
cables are similar
types.
