Poor Video Signal
Determine if wiring
polarity at “Video
Connector” terminal
block is correct.
Check the cable and
BNC connector.
If still no video,
connect the camera
directly to monitor.
Check the video
signal. If okay, the
problem is with the
interconnections. If
still no video, contact
BOSCH Service
Center. See rear
page of this manual
for contact
information
