CCTV System Cable length calculation

Here you can calculate the voltage rating flowing in a video surveillance system, an important value to verify if enough tension will arrive to cameras.
The calculator is based on continuous power (DC)

Cable Section (mm2)
Spec. res.: {{sezione}} Ωm
Section Length
{{lunghezza}} m
mA drawn
{{mA}} mA
Supply voltage:
{{volt}} V

Voltage drop {{(((sezione*lunghezza)*mA)/1000) | number: 2}} (V)

Voltage at the end of cable: {{(volt-((sezione*lunghezza)*mA)/1000) | number: 2}} (V)
