A standard CCTV RG59-0.59/3.7+2x0.5 cable has two wires 0.5mm2 each. Theoretical resistance is 3.4Ω/100m. Manufacturer data is 5.5Ω/100m. In powering cameras with 12V DC over CCTV cable and on the assumption that the voltage will fall to 11V, the power may be delivered over the following distances:
Max. distance at R=3.4Ω/100m |
Max. distance at R=5.5Ω/100m |
