20-piece passive video balun kit

This kit contains 10 pairs of passive video baluns designed for CCTV installations. They convert a BNC male connector to a terminal block so that standard twisted-pair cable can carry the video signal. The package suits installers who need to deploy multiple cameras quickly without external power supplies.

BNC-to-terminal-block wiring

Each balun is a passive device that requires no power, reducing points of failure in the field. The terminal-block interface accepts bare wires from Cat5 or similar twisted-pair cable, eliminating the time and reliability concerns of crimping RJ-45 plugs. Twisted-pair runs also reject EMI and RFI more effectively than coaxial cable.

1,000-foot monochrome and 800-foot colour reach

The single specification that determines suitability is the maximum transmission distance: monochrome signals travel up to 1,000 feet and colour signals up to 800 feet over ordinary twisted-pair cable. Installations requiring longer colour runs or active signal amplification will need a different solution.

Questions about this item

What distance does the VB21420 balun support for colour video over Cat5 cable?

The passive balun transmits colour video up to 800 feet over twisted-pair cable such as Cat5.

What physical connectors are on each balun for mounting and wiring?

Each unit has a BNC male connector on one side and a screw-terminal block on the other for direct wire attachment.

How are the VB21420 baluns installed and what common step should be avoided?

Connect a balun at each end of the cable run, secure the twisted-pair wires to the terminal blocks — no RJ-45 crimping is required.
