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:

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.
