Having been around for nearly a century now, coaxial cables are still quite relevant in today’s world mainly due to its high property shielding quality. The shielding helps in preventing any interference with the signal. The copper plate in such cables helps in quickening the transmission of data. It’s a lot easier to install, coming in two sizes for CCTVs:
This particular cable is made for higher bandwidth, made of copper and aluminum, and for higher frequency. Therefore, it isn’t ideal for indoor CCTVs. It’s a lot heavier than its other types, thus perfect for CCTVs used by city authorities, administrations, police authorities.
Like CCTV, cable television (CATV) is also typically wired using RG59 or RG6 coax cable, however it is not the same type of RG59 or RG6 that is used for CCTV installations. The difference is that the center conductor / inner conductor of CATV grade cable is made of steel or copper plated steel instead of copper. Steel has a much higher resistance than pure copper which leads to video loss at low frequency. Steel costs less than copper, which makes CATV cable cheaper than CCTV.
CATV systems are able to use cable with a steel center because cable TV video uses much higher video frequencies than CCTV. The copper plating of clad cable is thick enough so that none of the radio frequency energy penetrates into the steel core to induce loss. CCTV video uses much lower frequencies which are lost or dropped when using steel or steel clad cable.
To identify RG59 or RG6 for CATV, check the product specification and be on the lookup for terms such as “copper clad steel”, “aluminum foil inner shield”, “aluminum braid shield”. These are all characteristics coax cable that is used for CATV cable and should not be used for CCTV.
