There are many different types of connectors used in digital video security and surveillance systems such as the BNC to RCA adapter for example. In this article we’ll try to cover BNC and RCA connectors and adapters.
BNC is an acronym for Bayonet Neill-Councelman. Paul Neill and Carl Councelman. Neill worked for Bell Labs and invented something called the “N” connector. Carl Concelman worked at Amphenol and invented something called the “C” connector. Octavio Salati, a graduate of the Moore School of Electrical Engineering of the University of Pennsylvania filed a patent for a connector for coaxial cables that would solidly hold the cable but would minimize wave reflection or loss. The patent was made official in 1951.
