StarTech ST124HDBT 3 Port HDBaseT HDMI Extender Kit
Overview
The StarTech ST124HDBT is a 1‑to‑3 HDBaseT HDMI extender kit that distributes one HDMI source to three remote displays using standard Cat5e/Cat6/Cat7 cabling. It’s engineered for corporate AV, digital signage, classrooms, retail, and hospitality installations where multiple distant screens must mirror a high‑definition source without separate switchers.
The kit includes one transmitter with a local HDMI output and three HDBaseT receivers, enabling distribution of 4K UHD video (up to 4096×2160 at 30 Hz) up to ~35 m (115 ft) and 1080p up to ~70 m (230 ft). HDBaseT technology carries uncompressed video and audio over a single twisted pair cable and supports IR extension for remote control.
Deployment is point‑to‑point with receivers at display endpoints and a transmitter near the video source. It’s suitable for AV racks, wall mounts, or ceiling installations requiring long‑reach HDMI distribution. Not suitable for multi‑endpoint IP network AV distribution or HDMI matrix switching without conversion infrastructure.
