Discontinued. Extend composite video, stereo audio, and IR signals up to 1000 feet via CAT5 cabling.


SmartAVI’s HDC-VX extends composite video, stereo audio, and IR control signals up to 1000 feet away via a single CAT5 twisted-pair (UTP) cable.

Affordable & Reliable AV Extension

The HDC-VX offers cost-efficient, high-quality signal extension with popular UTP CAT5 cabling. UTP twisted-pair CAT5 cables are even more reliable than standard single-cord extension chords, designed for high-ground loop immunity from atmospheric interference that otherwise interrupts signal transmission. Better yet, UTP CAT5 extension is amongst the most affordable ways to boost AV signals on the market, so cost-conscious users will always be pleased!

A Great Fit in Many Environments

An ideal AV extender in innumerable applications, the HDC-VX excels in retail spaces, office buildings, schools, transportation hubs, and more! The HDC-VX is outfitted with convenient IR control signal extension as well, perfect for sending commands to connected AV devices, such as volume adjustment and switching between input channels.
