Product Description
A passive video balun converts a BNC video signal to RJ45 so HD-over-coax cameras can run on Cat5e or Cat6 UTP cable instead of coax. Units work in pairs — one at the camera, one at the DVR/NVR — and need no external power, which keeps site wiring simpler and removes a power supply as a failure point.
Where this fits on a job
This suits installers re-using structured cabling already in a building, or extending runs where pulling fresh coax isn't practical: office refurbishments, retail units, warehouse extensions and residential blocks with existing network points. Because it's passive, it's a straightforward add rather than a system change.
Key specs
- Video formats supported: HD-TVI, AHD, CVI and standard analog — confirm the camera and recorder both use one of these, not IP/PoE
- Resolution: up to 8MP (4K), so it covers current HD-over-coax cameras rather than only older analog ones
- Cabling: Cat5e or Cat6 UTP between the two baluns
- Connectors: BNC male for the camera or DVR side, RJ45 for the cable side
- Contacts: gold plated BNC contacts, specified to improve signal stability and reduce connection loss
- Power: passive design, no external supply required
Order in pairs for each camera run — one balun alone won't complete the link between camera and recorder.

Frequently Asked Questions
Does this balun need a power supply?
No — it's a passive design, so no external power is required at either end.
Will it work with an IP or PoE camera?
No — it supports HD-TVI, AHD, CVI and standard analog video formats, not IP/PoE signals.
Which cable should I use to link the baluns together?
Cat5e or Cat6 UTP cable, connecting a balun at the camera end to a matching one at the DVR or NVR end.
What resolution can it handle?
It supports CCTV cameras up to 8MP (4K) using HD-over-coax formats.
