Our entry level HDMI HDBaseT Extender Kit enables a HDMI display to be located up to 70 metres away from the source device. It can conveniently be extended using only one Cat5e / 6 / 6a / 7 cable, providing a cost effective and reliable solution to running a HD signal over distance.

It not only supports HDMI (3D, Deep Colour) but also Ultra HD (4k x 2k) and is HDCP compatible. It is perfect for the meeting room, home theater or any installation that needs long distance transmission and superior video quality.

The HD-EX354K does not offer PoE and will require the included power supplies to be conneted at the transmitter and receiver end. IR can be sent bidirectionally controlling both the display from the source device and vice versa using the included IR receiver & emitter.
