Which connector type typically connects to video, CATV, and security cameras?

The connector that is commonly associated with video, CATV (cable television), and security cameras is the BNC connector. BNC stands for Bayonet Neill-Concelman, and it is designed to provide a secure connection for coaxial cables, which are typically used in these applications.

The BNC connector is favored in these contexts because of its ability to handle video signals with minimal signal loss and noise. The bayonet-style coupling mechanism allows for a quick and secure connection, which is particularly beneficial in installations where equipment may need to be frequently connected and disconnected, such as in security camera setups and broadcast industries.

In contrast, Series 11 and Series 6 connectors are typically used for specific RF or coaxial cable applications but do not have the same widespread standardization for video and security uses as the BNC connector does. N connectors are primarily used for high-frequency applications and do not cater to the typical video connections found in CATV or CCTV setups.

BNC connectors are therefore the most appropriate choice for connecting to video equipment, CATV, and security cameras due to their alignment with standard practices in these fields.
