Full copper RG59/2 is the professional specification for permanent CCTV cable installations. The centre conductor of the video coax and the power conductor are both solid copper rather than copper-clad steel (CCS), providing significantly lower resistance over long cable runs, better signal integrity at the camera positions, and more reliable long-term power delivery to the cameras.
Copper-clad steel alternatives are available at lower cost but the steel core increases resistance, which reduces the effective range of the cable and causes greater voltage drop on the power conductor over long camera runs. For professional installations where cameras are positioned at 30 to 100 metres from the DVR, full copper is the correct material specification.
The twin construction of RG59/2 combines the coaxial video conductor and a parallel power conductor in a single jacket, allowing one cable to carry both video signal and 12V power from the DVR/power supply position to the camera, eliminating the need for separate power cabling.
The black colour is the standard for outdoor CCTV cable, suitable for routing on external walls, along rooflines, and through conduit. The UV-resistant jacket withstands outdoor exposure without degradation.
For CCTV installers completing professional permanent camera installations using RG59/2 cable across London and the UK, the SFX 200M full copper drum is the correct specification for long-run outdoor installations where signal quality and minimal voltage drop are important.
