The video signal can be transmitted via this cable for distance up to 400m without any amplifier using necessary.
The CCTV specialistic cable Rg59+2X0.50 has 2 wires of 0.5 mm² each. Theoretical resistance is 3.4Ω/100m. Manufacturer data is 5.5Ω/100m. In powering cameras with 12V DC over RG59+2X0.50 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 |
