Caution: Once power is supplied, do not remove the camera from the mounting base due to risk of
electrical shock.
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:

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.
