Voltage Drop Calculator Tool

Use this handy tool to calculate the DC or AC voltage drop for a length of cable.

How to use this tool:

  1. Enter the initial voltage. Choose if your system operates on 12V or 24V.
  2. Select AC or DC.
  3. Enter the current of your camera in amps. Note: 1 amp = 1000mA.
  4. Enter the distance of your cable in feet. (1meter = 3.28 feet)
  5. Enter the size of your cable.
  6. Click 'Calculate.' or Click 'Cancel' to clear the results and start again.

1. Initial Voltage  

2. AC / DC  

3. Current (Amps) 

4. Cable Length (ft)  

5. Cable Gauge (AWG)  

Calculate   Cancel


Note: Industry standard is a voltage drop of no greater than 10%.
