ATEN 4-Port HDMI CAT5e/6 Splitter over Single Cat Cable / 4K / RS232 / HDBaseT

Product Overview

AI-generated summary

The ATEN 4‑port HDMI‑over‑single‑Cat5e/6 splitter is the kind of “it has to work every day” kit you buy when you need reliability more than you need cheap. It’s especially useful for boardrooms/classrooms where you want to run HDMI signals over longer cable runs without messing around with repeaters and adapters, and the RS232 element is a big deal in real deployments because it makes integration with AV control systems and display management much smoother. At ~£1,226 ex‑VAT you’re definitely paying for that “proper installation” factor—this isn’t for hobbyists or one-off installs where you could just use shorter HDMI and standard switches.

That said, I’d only recommend it if you actually need the split‑plus‑extension design (one HDMI input distributed to multiple remote displays) and you’re comfortable designing the system around how the unit behaves with multiple endpoints. If you only need a couple of screens over distance, or you don’t need RS232/control, you may find better value by mixing simpler distribution with dedicated extenders/switching rather than paying for a combined box. Who should buy: integrators/resellers and IT/AV teams standardising installs across sites. Who shouldn’t: anyone looking for a bargain replacement for a basic HDMI splitter, or a casual “plug it in anywhere” solution.
