  • Transmit 4K video up to 396 ft over Category 7 cable
  • Power both transmitter and receiver through PoE eliminating extra adapters

  • Wall-mountable design fits cleanly into professional AV installations

4K HDMI over IP Extender Kit

The CEH28A11S1 transmits a single HDMI source to a single display up to 396 ft over Category 7 twisted-pair cable. It supports video modes from 480p through 2160p at a maximum resolution of 3840 x 2160. The kit includes a transmitter, a receiver, two power adapters, IR extension cables and mounting hardware.

Installation uses two RJ-45 ports and PoE power

Connect the transmitter to the source and the receiver to the display with a single Category 7 run; each unit draws power over Ethernet so only the two included adapters are required. The wall-mountable enclosures measure 1.09 by 6.81 by 5.19 inches and weigh 1.41 lb and 1.44 lb respectively. A common issue is exceeding the 396 ft limit or using lower-grade cable, which causes signal drop-out.

Sustained 4K60 delivery at 18 Gbps

The extender maintains 18 Gbps bandwidth continuously at 50 Hz or 60 Hz refresh rates without compression artifacts during long sessions. PoE power delivery remains stable across the full cable distance. It does not suit installations needing multi-source matrix switching, runs longer than 396 ft, or fibre-based infrastructure.
