Troubleshooting
No picture after providing power
 Check the power connection to the power supply to the power outlet for connectivity.
 Check the power supply voltage.
 Check all connecting cable and monitors for loose connections.
 Check the monitor settings
The picture has interference or ripples
 This may be caused by the power supply’s arc, poor quality cable, too long cable, or improper
ground connection.
The picture background color changes continuously
 A fluorescent light’s electromagnetic field may cause color roll. Reduce the number of
fluorescent lights or increase the distance between the camera and the lights to reduce this
effect. Use of a power supply with external sync may solve the problem.
Blurred Image
 Check the dome cover for dirt or imperfections
 Check the focus to make sure adjusted correctly
 Check the lens of the camera to make sure it is clean. Only use a dry, clean lens cloth to clean
the lens. Never touch with your fingers.
