Why Use a Passive Video Balun?

Coaxial cable is bulky and expensive to run across large properties or commercial buildings. A passive video balun lets you use everyday CAT5 UTP network cable — which is thinner, lighter, and cheaper — to carry high-definition CCTV signals without any signal degradation over typical installation distances.

Frequently Asked Questions

Q: What is a passive video balun transceiver and how does it work?

A: A passive video balun (also called a passive transceiver) is a small adapter that converts the BNC coaxial signal from a CCTV camera or DVR into a balanced signal that can travel over standard CAT5/CAT5e UTP twisted-pair cable. Because it is passive, it requires no external power supply — the transformer inside handles the conversion automatically, making installation quick and straightforward.

Q: Which camera and DVR formats is this video balun compatible with?

A: This passive transceiver is compatible with HD CVI, AHD, and TVI analog HD formats, as well as 4K twisted-pair systems. It supports camera resolutions of 2MP, 3MP, 4MP, and 5MP, making it suitable for most modern analog HD CCTV setups.

Q: How far can I run a CAT5 cable with this balun?

A: The Anpwoo 500C passive video balun supports transmission distances of up to 200 metres (approximately 656 feet) over CAT5 or CAT5e UTP cable, which covers the vast majority of residential and small commercial CCTV installations.

Q: Do I need to buy baluns in pairs?

A: Yes — you need one balun at the camera end and one at the DVR/recorder end to complete the signal path over UTP cable. This listing offers multiple cable length and quantity options to suit your specific installation.

Q: Will this balun save me money compared to running coaxial cable?

A: Absolutely. CAT5/CAT5e UTP cable typically costs 10–20% less than equivalent coaxial cable and is easier to route through walls and conduits. Using passive video baluns lets you take full advantage of that savings without sacrificing HD video quality.
