Product Description
What it does
This is a straightforward BNC female-to-female coupler: it joins two BNC male-terminated coaxial cables so you can extend a cable run without re-crimping a new connector. If a camera cable falls short of the DVR by a metre or two, this is the fix rather than running a whole new cable.
Where it fits
- Works with RG59 and RG6 coaxial cable — the two coax types used in most CCTV runs.
- Supports analogue CCTV, HD-TVI, AHD and CVI video signal formats, so it's not tied to one camera system.
- Suits camera-to-DVR connections, junction boxes, and extending runs inside rack-mounted CCTV setups.
Build
The body is precision metal, which gives stable electrical contact at the joint — important because a loose or corroded coupler is a common cause of a snowy or dropped picture. The design is compact and inline, so it sits neatly in a cable run or enclosure rather than adding bulk.
Before you buy
Check your existing cable is BNC-terminated RG59 or RG6, and confirm your camera/DVR uses one of the four supported formats above. This coupler joins cable — it doesn't convert between different connector types or video formats.

Frequently Asked Questions
What cable types does this coupler work with?
It's compatible with RG59 and RG6 coaxial cable, the two types most commonly used in CCTV installations.
Will it work with my HD camera system?
Yes — it supports analogue CCTV as well as HD-TVI, AHD and CVI formats, so it doesn't lock you into one camera type.
Can I use this to join two cameras' cables at a junction box?
Yes, it's designed for exactly that: joining two BNC male-terminated cables inline, including inside junction boxes or cable runs.
Does the metal body affect signal quality?
The precision metal construction is there to keep electrical contact stable, which helps maintain signal integrity across the joined cable run.
