1080 HD-SDI Camera
TROUBLE SHOOTING
PROBLEM SOUTION
Nothing appears on the screen.
Check that the power cord and line connection between the camera and
monitor are properly connected.
Check that video cable is connected with the Analog BNC (Yellow).
When the camera’s HD-SDI BNC output is directly connected to the
monitor’s BNC terminal: Make sure the monitor supports HD-SDI signal input.
When the camera’s HD-SDI BNC output is connected to the DVR: Make
sure the DVR supports HD-SDI signal input.
HD-SDI output is converted into other format such as DVI and VGA by
using video converter: Make sure the converter’s HD-SDI input format
The image on the screen is dim.
Is lens stained with dirt? Clean your lens with soft, clean cloth.
Set the monitor to the proper condition.

HD-SDI video may not appear to be normal if distance exceeds the
maximum transferrable distance.
When a BNC cable adaptor is used to combine two or more BNC cables
for distributed HD-SDI video transfer, make sure the impedance of the
adaptor is 75Ω. Otherwise, it may cause shorter transfer distance or
broken video transfer.
