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.
Connections
1. Use a BNC connector to connect the camera’s VIDEO OUT to the monitor’s (or DVRs) VIDEO IN. Use the following
recommendations for cable types and distances:
Maximum Cable Length
Type of Coaxial Cable RG-59/U RG-6/U RG-11/U RG-15/U
Recommended Max
Cable Length 250 M
825 ft 500 M
1650 ft 600 M
1980 ft 800 M
2640 ft
2. The power is DC 12V (+/- 10%) / 350mA. Use the following recommendations for cable types and distances:

Resistance (Ω/ft) 0.024 0.015 0.009 0.005
Use the formula below to calculate the power cord and power supply. “L”, “R”, “VA”, “I” shall satisfy the inequality below:
10.8 V DC ≤ VA - 2 (R x I x L) ≤ 16 V DC
L = Cord length (m or ft)
R = Resistance of copper wire (Ω/m or Ω/ft} VA = DC output voltage of power supply unit
I = DC current consumption (A).
3. Connect power supply to the camera’s POWER IN terminal.
