J-Tech DigitalHDbitT Series ONE TO MANY CONNECTION Ultra HD 4K HDMI Extender Over TCP/IP Ethernet/over Single Cat5e/cat6 Cable Ultra HD 4K with IR Remote - Up to 400 Ft (Receiver Only)

You literally just plug these into a switch. It's fantastic. I will say that I still occasionally get some stutter in the audio while using these. I'm running on CAT-6A & CAT-8, so I feel certain that is not the issue. I haven't tried 4K video over them for a long period of time over, most of my experience was with 1080p video, but based on the short time I tried 4K and all the hours of TV on 1080p I have confidence that they'll work well. I had a dud at first and the company replaced the receiver at no extra charge.

We have many of these at our church and they work great, no issues at all. Great brand!

Device is easy to install and use. Just plug and play. Clear labeling by each port so there will not be any confusion on what's input/output. Very happy with the product.

these devices truly work and were able to receive communication through a network setup instead of a direct ethernet connection! so happy i purhcased these. Great company and great people would recommend for any one looking to add more mirrored screens to a location from a computer or any device.

Works well, only odd thing is that there was a slight delay issue between the transmitter and the 2 other receivers we purchased separately. We made it work though.
