  • Transmit 1080P video up to 450 m over Cat5/6 cable
  • Combine video, audio and 12-36 V DC power on one twisted-pair run

CCTV balun pair for video audio power

Two passive baluns convert BNC video RCA audio and 12‑36V DC onto a single Cat5 or Cat6 run. Each unit has a BNC male video connector a 5.5×2.1 mm DC jack pair and an RCA male audio lead. The 16 cm pigtail keeps the camera junction tidy while the RJ45 female port accepts standard UTP cable. Supports 720P 960P and 1080P signals across CVI TVI AHD and CVBS formats.

ABS shell metal contacts tool‑free install

The ABS housing with metal contacts resists handling wear and needs no crimping tools. Simply plug the BNC side into the camera or DVR patch the RJ45 into the structured cable and connect the DC and RCA leads. Passive design means no local power supply at the camera end just the 12‑36V source already feeding the system. The short tail reduces strain on the BNC port during panel mounting.

Replaces coaxial runs up to 450 m CVI

Swaps 75 ohm coax for Cat5e or Cat6 delivering CVI video up to 450 m TVI or CVBS up to 250 m and AHD up to 320 m. Worth the jump when existing twisted‑pair infrastructure is in place or when pulling coax is impractical. Not suited for runs beyond the stated distances or for installers who need active equalisation or PoE injection on the same cable.
