Product Overview

AI-generated summary

StarTech’s HDMI-over-CAT5e extender is one of those “boring but reliable” solutions that works when you need a clean video run without paying for fibre or ripping out walls. For ~£293 ex-VAT, I’d only buy it if you genuinely need the extra distance and the convenience of having IR/serial pass-through—because if your use case is just “send HDMI across a room,” you can usually find cheaper options that don’t lock you into a more complex installation. In the real world, these extenders tend to behave best when the cabling is decent (properly punched terminations, not mystery patch leads) and you’re not pushing right up to the edge of the supported length.

Who it’s for: corporate AV in training rooms, meeting spaces, reception areas, classrooms, and any setup where you want to control a source device from the display side (IR) and/or integrate with a control system (serial). Who should avoid: anyone expecting this to be a universal replacement for HDBaseT kits on higher-spec cabling runs, or anyone who can’t guarantee consistent CAT5e quality—because that’s where you’ll start seeing dropouts, handshake quirks, or “works most of the time” frustration. My advice: if you’ve confirmed your cabling plan and you actually need IR/serial, it’s a solid value; if not, you’re paying for features you may never use.
