Availability: In stock


This HDMI over CAT6 extender with 3-port HDMI switch features HDBaseT™ and is TAA Compliant.

Astonishing 4K over CAT6

This HDMI Extender with a built-in Switch is capable of extending 7.1 audio and 4K at 30Hz video up to 115ft (35m), or 1080p up to 230ft (70m). The transmitter and receiver kit is connected using a single CAT5e/6 cable to avoid the hassle of running multiple cables.

Simplified Professional Installation

The HDMI Switch Box and Extender supports Power-over-Cable, meaning both the transmitter and receiver can be powered by the same single power source. Power-over-Cable is great for extending video to areas where power outlets may be limited, such as industrial sites. Use the metal housing, grounding bolts and included mounting brackets to create professional installation options, ideal for digital signage, boardrooms, and tradeshow applications.

Effortless Control with Automatic Switching

The 4K 30Hz HDMI extender box features several methods of input adjustment. Auto-detect switching selects newly connected devices, whereas priority selection allows you to choose the default active port. The IR Remote Control (batteries not included) and serial switching, using the included RJ-11 to DB9 adapter, offer additional input selection methods.

VS321HDBTK is backed by a StarTech.com 2-year warranty and free lifetime technical support.
