4K HDBaseT Extender Kit

The AV Access 4KEX100-L is a transmitter and receiver pair that sends uncompressed 4K@60Hz video, multi-channel audio, Ethernet, RS232 and two-way IR over a single CatX cable. It reaches 100m at 1080P and up to 70m at 4K@60Hz on Cat5e/6, extending to 100m at 4K on Cat6a/7. One power adapter supplies both units via bi-directional PoE.

Build Quality and Daily Connections

Each unit places every connector on the same side for tidy cable routing and includes LED indicators for power and link status. The kit provides HDMI 1.4 input and output, a 10/100 Ethernet port for network relay, RS232 for control systems and IR ports for remote-command pass-through. Built-in surge and ESD protection meets FCC and CE certification.

Check Your Setup Before Ordering

Verify that your source and display work with HDMI 1.4 and HDCP 2.2 and that 4K@60Hz 4:2:0 8-bit output satisfies your colour requirements. Ensure you have Cat5e or better cabling rated for the distance you need, and confirm that a single DC power supply location is practical for the installation. Buyers needing HDMI 2.0 bandwidth or longer 4K runs on Cat5e should consider other solutions.

Questions about this item

What HDMI standard does the 4KEX100-L use and what resolution limit does that impose?

The extender uses HDMI 1.4, which limits 4K@60Hz output to chroma sub-sampling 4:2:0 8-bit only.

What cable category and length are required to run 4K@60Hz the full 100 metres?

You need Cat 6a or Cat 7 cable to achieve 4K@60Hz at the maximum 100 m distance; Cat 5e or Cat 6 only reaches 70 m for 4K.

How is the pair powered and which connection step is most often missed?

A single DC power adapter on either the transmitter or receiver feeds both units through bi-directional PoE, but installers often forget to link the two units with a solid CatX cable before applying power.
