How to use this Calculator Tool: Fill in the Voltage, AC/DC and Amps fields below to the specifications of your power source. Then enter the length of the cable from the power source to the camera and then the gauge of the cable you will be using. Finally you may click the "Calculate Voltage Drop" button.

Voltage Drop Calculator

All security cameras have minimum power requirements. When running long lengths of cable you may experience a drop in voltage that will cause loss of video quality or the camera may not work at all. This Voltage Drop Calculator will assist you in determining the total voltage loss over a specified distance and the voltage you will have at the destination.
