BNC (Bayonet Neill-Concelman) cables are coaxial cables that are widely used, especially for the transmission of video signals. BNC connectors are known for their fast and secure connection, and are often used in surveillance cameras, television sets, and other professional video and signal transmission systems. BNC cables offer good protection against signal interference and support high quality signals, especially in analogue video systems.

BNC cables are also widely used in radio and telecommunication systems. Their special locking mechanism ensures a strong and stable connection of the cable. Although BNC cables are less common nowadays with the spread of digital interfaces, they remain an important part of many professional applications and systems.
