AV Access HDMI KVM USB Extender Over Cat5e/6/6a/7 260ft/80M, 2 USB2.0 Ports, Zero-Latency, Plug and Play, No Driver, Supports All Operating System, Keyboard and Mouse USB Over Ethernet

Great product. Used for remote control of a PC which is stored in my conservatory and being controlled from living room. Works amazingly well! There is no latency issues either. USB transfer rate is great too. Well worth the money. I would highly advise. I have also tried with a CCTV NVR unit and works fine with Hikvision too.

Lightweight and discreet but quite expensive.

The video signal has noticeable compression artefacts. Be aware it is not "uncompressed" as described.

HDMI cables cannot just be extended to whatever length you want. In my experience anything over 15m can result in loss of signal and certainly 20m will. So when you have 4 TV's around a building all playing back the same signal you need one of these for each extra TV - an amplifier at each end of the cable.So these metal boxes all have a power supply socket (mains adaptor supplied) and an HDMI socket on one end. The other end has an RJ45 network socket. The idea is that you lay an ethernet cable between your video source and your screen and plug one of these "repeaters" (you could just as well call them amplifiers) at each end.Remember each end needs a mains supply!These perform perfectly and I used them with a 50m RJ45 cable in-between them.These do exactly what they claim and do so very well indeed. I cannot put into words how well these perform - they are absolutely excellent!

This set of HDMI/UTP TX and RX worked very well for me. I needed to get a computer's HDMI output to a conference room in another part of the building. I used the existing IT department data cabling, bypassing all Ethernet equipment, to join the TX and RX together. These are NOT Ethernet based, but use the same copper/UTP cabling as Ethernet. Power LED, Status LED all serve to help in troubleshooting. Chassis are steel, come with mounting brackets/screws. I would buy again. I did not need any tech-support so I left that review blank. Picture quality was hard to judge since my source material was not prime quality to begin with. My customer saw no difference. I am only using it for video content through the HDMI, so I can't attest to any audio/sound performance.

Intended to use for CCTV application (Lorex DVR) it did not provide resolution higher than 1024x768 and the usb function (mouse only) did not work.
