Nitek N1-VB31AT Video Power Balun Combiner

The Nitek N1‑VB31AT (VB31AT) Video Power Balun Combiner is a compact and passive device designed for CCTV systems, enabling both video and power transmission over a single category cable (CAT5/UTP). Housed in a rugged ABS housing with mounting tabs, it measures just 0.9″ H × 1.0″ W × 2.0″ D and weighs mere ounces—ideal for tight installations. It routes composite video over one twisted pair and camera power over two others, reaching up to 750 ft (225 m) on standard UTP or up to 100 m on structured wiring, while passing 250 mA at full distance or 1 A over shorter runs. The unit features built‑in surge suppression, strong immunity to noise, and compatibility with HD‑TVI, CVI, AHD, NTSC, and PAL formats. With a lifetime warranty and no external power requirement, it simplifies wiring and boosts installation reliability.
