OREI 4K HDMI Extender Balun over Ethernet – HDR, IR, PoC, RS-232, 400 ft

Experience cinema-like detail with the OREI 4K HDMI over Ethernet Extender Balun. Built on HDBaseT technology, this system transmits UHD video and audio over CAT5e/6/7 cables up to 400 feet, delivering 4K at 60Hz with 4:4:4 chroma and 18 Gbps bandwidth. HDR support, including HDR10+ and Dolby Vision, helps deliver richer contrast and more vibrant colors without compromising clarity or motion.

Designed for flexible setups, this extender supports HDMI 2.0a, HDCP 2.2, and a range of audio formats, while offering practical features that simplify installation. Bi-directional IR control lets you issue source commands from the display room or manage the remote display from the source location. CEC compatibility adds convenient device coordination, and PoC (Power over Cable) enables power to flow from one side to the other, reducing cable clutter and requiring fewer power adapters. An HDMI loop-out on the transmitter enables a local display from the source without needing an extra splitter or multi-device switch.
