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.
