Four passive balun pairs send monochrome video up to 1000 feet or colour up to 800 feet over Cat 5 cable without external power
This kit contains four pairs of passive video baluns that convert a 75 ohm BNC connection to a terminal block for Category 5 twisted-pair cable. Installers use them to run analog CCTV camera signals over structured UTP wiring instead of coaxial cable. The passive design needs no external power supply at either end.
Because the units are completely passive they draw zero power and add no active noise to the signal path. The twisted-pair medium provides better EMI and RFI rejection than traditional coaxial cable in typical building environments. No power adapters or transformers are required at the camera or recorder side.
Monochrome video can be transmitted up to 1000 feet and colour video up to 800 feet over Cat 5 or better cable. The baluns support NTSC, PAL and SECAM analog formats and connect via a BNC male plug to a screw terminal block for fast installation. Distances beyond these figures are not supported by the passive design.

| Specifications | • Transmits monochrome video signal up to 1,000 feet or color up to 800 feet• Passive devices do not require power• BNC Male to terminal block, fast installation |
| Features | •Better EMI and RFI interference rejection than coaxial cable•Lower cable cost: The cost of baluns plus Cat 5 cable may less than traditional wire. Especially for high cost Plenum Coax cables•Utilize existing wiring: already have structured cabling systems, simply connect a balun at each end of the cable run to transmit your signal |
| Package Contents | 4 pairs passive video balun |
Strip each Cat 5 wire, insert into the screw terminals matching polarity, and tighten; the BNC male plugs directly into the camera or DVR — no soldering required.
The passive VB201P4 has no active components or power supply, so it does not wear out; only the Cat 5 cable or connectors would need attention if damaged.
Colour transmission is rated to 800 ft; beyond that the signal remains for monochrome up to 1000 ft, so colour loss is the first limit encountered.
