Product Description
What it does
This adapter mates a BNC female interface to an RCA male plug, letting RCA-terminated leads connect straight into BNC ports on cameras, DVRs and monitors without re-terminating the cable.
Signal compatibility
It passes analogue composite video, and the same coax path also carries HD-TVI, AHD and CVI signals provided the rest of the run — cable, connectors, source and sink — is built for those formats. The adapter itself is a passive connector; it doesn't add or process signal.
Cable and installation notes
Intended for use on RG59 and RG6 coaxial runs typical of surveillance installs. Metal-bodied construction is used for the contact interface, aimed at keeping electrical continuity solid at the join rather than relying on a crimped or soldered joint. The inline, compact form factor suits tight spots — rack backs, junction boxes, behind wall plates — where a bulky coupler won't sit.
Where it's used on a job
Common on:
- Mixed-connector installs where existing RCA leads must feed BNC-only DVR inputs
- Bench testing, when swapping between BNC test leads and RCA-terminated cameras
- Structured cabling systems where connector standardisation wasn't done at first fix
Fit is mechanical only — check the actual DVR/camera port type (BNC vs RCA) before speccing this in, since not all analogue kit shares the same default connector.
Frequently Asked Questions
Will this adapter work with HD-TVI, AHD or CVI cameras?
Yes, it passes those signals over coax as long as the camera, cable and DVR at both ends already support that format — the adapter itself is just a passive connector, not a signal converter.
What cable types is this adapter suited to?
It's intended for use on RG59 and RG6 coaxial cable, the types typically installed in CCTV surveillance runs.
Does the adapter change or boost the video signal?
No. It's a mechanical BNC-to-RCA connector that maintains the electrical path; it does not amplify, convert or process the signal.
Where would I typically fit this on a job?
Common uses include joining RCA-terminated leads to BNC-only DVR inputs, bench testing between BNC and RCA gear, and tidying up structured cabling where connector types were mixed at first fix.
