10. TROUBLESHOOTING
Problem Solutions
Nothing appears
on the screen.
a. Check that all connected devices are powered on.
b. Confirm that the voltage is correct.
c. Confirm that the power supply provides enough current to power the
camera.
d. Check that all video cables are correctly connected.
The picture is not
clear.
a. Check that your monitor is correctly adjusted.
b. Confirm that the glass in front of the lens is clean. If there is dust, dirt,
or fingerprints on the glass, the image quality will be affected. To clean
the glass, use a soft, dry, and non-abrasive cloth or a commercially
available lens cleaning set.
c. Correctly adjust the focus.
The picture has
interference.
a. The camera may be close to a high voltage source, such as a power
generator.
b. The BNC cable is not terminated properly.
c. The video cables are not connected properly.
The picture
is flickering
continually.
a. Check the termination and set the impedance at 75Ω properly.
b. Ensure that the camera is not pointing towards the Sun or any light
source.
c. Check if there is any intermediate device.
d. Check if the distance of the video cable exceeds the maximum
transferable limitation.
The camera is
not synchronizing
with the reference
signal.
a. Make sure Tri-Level reference signal is used.
b. Locking takes up to 1 minute depending on the signal strength. Make
sure the sync LED is solidly lit.
c. Check if the cable and connectors used in reference sync are in good
condition.
d. Make sure the cable length used in reference sync does not exceed 100
ft.
e. Make sure OUTPUT EN is on when using the genlock output.
Focus The miniature (M12) lens that comes installed on camera is set to optimal
focus position, however if lens is slightly out of focus rotate lens clockwise
or counter-clockwise slightly to fine tune. Once the desired focus point is
achieved, rotate the locking nut back towards the camera which will hold
the lens position at optimal focus point.
