4K 30Hz HDMI POE Extender Kit

This kit includes one transmitter and one receiver to extend HDMI video and audio signals up to 120 metres over a single Cat5, Cat6 or Cat7 cable. It supports a maximum resolution of 4Kx2K at 30Hz and is suited for installers connecting sources such as set-top boxes, disc players or consoles to remote displays. Power over Ethernet removes the need for a separate power supply at the receiver end.

Sustained transmission over 120 metres

The extender maintains a stable 4K 30Hz signal across the full 120 metre distance without signal degradation typical of shorter-run solutions. IR control signals travel alongside the video stream, allowing reliable remote operation of the source device from the display location throughout extended use. POE delivers consistent power to the receiver without voltage drop over the cable run.

Single-cable installation with POE

A single Ethernet cable carries video, audio, IR and power, reducing cable count and simplifying routing through walls or conduit. The transmitter and receiver units feature HDMI 4.0 ports and dedicated IR blaster and receiver connections for discrete control. This design suits permanent installations where minimal cabling and remote source control are required.

Questions about this item

Does the extender add noticeable fan noise or heat when running continuously?

The kit uses passive cooling with no fan, so it adds no audible noise and only minimal warmth during all-day operation.

Which cables and power sources must I already have to use the transmitter and receiver?

You need one Cat5, Cat6 or Cat7 patch cable up to 120 m and an HDMI source and display; POE supplies power to the receiver so no local outlet is required there.

Will 4K 30 Hz video pass through my older 1080p display and legacy HDMI sources without handshake issues?

The extender is backward compatible with 1080p and lower resolutions, and the IR channel works with legacy STB, DVD or PS3 devices for remote control.
