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 Bosch
Security Systems
(see back cover for
contact details).

Ensure video cable is
correctly matched
and terminated with
75 ohms at each end.
