BNC Connectors for CCTV
Crimp, twist-on and compression BNC connectors for RG59 and coax CCTV installs — the fittings installers actually use, in stock in the UK.
Choosing the right BNC connector
Crimp BNC connectors give the most reliable joint on RG59 and are the trade default — they need a hex crimp tool but survive pulling and weather better than push-on types. Twist-on connectors need no tooling and suit one-off repairs, at the cost of long-term grip. Compression fittings sit between the two: tool-fitted, weather-tight, and increasingly the choice for external junctions.
Match the connector to the cable: RG59 and RG6 take different sizes, and shotgun (power-and-video) cable needs a connector plus a DC plug for the power pair. If you are running analogue HD (TVI/CVI/AHD) the same BNC fittings apply — the connector does not care about the signal format.
Frequently asked questions
Are BNC connectors the same for RG59 and RG6?
No — the crimp sleeve diameter differs. Check the connector is specified for your cable type; forcing an RG59 connector onto RG6 gives a weak joint that fails later.
Do BNC connectors work with HD cameras?
Yes. TVI, CVI and AHD analogue-HD signals all run over the same coax and BNC fittings as older analogue systems — upgrading the cameras does not mean re-terminating the cable.
What tool do I need for crimp BNC connectors?
A hex crimp tool sized for coax (typically with RG59/RG6 dies) plus a coax stripper. Compression fittings need their own compression tool instead.
