ZATECH GJC12B-8MP Video Balun - 600m Twisted Pair, 8MP HD CCTV Transmission

The ZATECH GJC12B-8MP video balun lets you run HD CCTV video over ordinary twisted-pair (network-style) cable instead of coax, extending transmission up to 600 metres with a clear, interference-free signal. It supports resolutions up to 8MP, making it suitable for high-definition analogue camera systems as well as standard-definition setups.

Twisted-pair cable is generally cheaper and easier to run over long distances than coax, and baluns like this one convert the camera's video signal for transmission over that cable before converting it back at the DVR end.

Key features

• Supports HD video transmission up to 8MP
• Transmission range of up to 600 metres over twisted pair
• Uses standard, affordable twisted-pair cabling instead of coax
• Delivers clear, interference-resistant video over long distances
• Suited to professional and residential CCTV installations

Ideal for

• Long camera runs where coaxial cable is impractical or costly
• Large residential, commercial or industrial CCTV installations
• Upgrading existing coax-based systems to twisted-pair cabling
• Sites needing reliable video transmission over extended distances

Good to know

A balun is needed at both the camera end and the DVR end of the cable run to complete the connection, so confirm whether this listing includes a matched pair before ordering. Actual maximum transmission distance can vary depending on cable quality, resolution used and local interference, so it's worth testing performance over your specific cable run during installation.
