What type of coaxial cable is used for video, CATV, and security cameras?

The correct choice for the type of coaxial cable commonly used for video, CATV (cable television), and security cameras is RG-6. This type of cable is designed with improved shielding and bandwidth capabilities, making it suitable for a variety of applications that require high-frequency performance, such as carrying video signals over long distances.

RG-6 cables typically offer better protection against interference, which ensures reliable signal transmission in environments where there may be multiple sources of electrical noise. The cable's design allows it to handle the higher frequencies that are often used in video applications more effectively than other coaxial cable types. This makes RG-6 a standard in residential and commercial installations where quality video signals are a requirement.

While Series-11, Series-6, and Series-59 cables may have specific applications within the coaxial cable nomenclature, they do not match the performance specifications and common usage scenario of RG-6 for video, CATV, and security installations. RG-6 is specifically tailored for these purposes, making it the preferred choice in the industry.
