BNC Connectors in CCTV Systems

A BNC (Bayonet Neill–Concelman) connector is used in analog CCTV systems to link cameras and recorders via coaxial cable. It provides secure and stable video transmission

This is the standard connector type used in CCTV. It provides an easy snap-on connection for a coax cable. What BNC stands for is less clear. Some say it means British Naval Connector. Others attribute it to the type and the inventor; Bayonet Neil Councilman.
