This 4k hdmi kvm usb extender HSV5631 uses Gigabit IP network technology to process and distribute 4K ultra-high-definition video signals. At the same time, the mouse and keyboard control signals are sent from the receiving end to the transmitting end to realize the KVM extension function. This hdmi usb extender can also support the full-featured USB2.0 extension, so the receiving end can be connected not only to the mouse and keyboard, but also to a U disk. USB camera, USB headset and other USB devices. This 4k hdmi kvm extender can support point-to-point KVM and USB extension. Through cascaded network extension of multi-level switches, this kvm extender can extend the distance of KVM and USB signal transmission to 20 kilometers.
This 4k hdmi kvm extender is also characterized by supporting lossless 4K ultra high-definition 4: 4: 4 format transmission, the overall delay is less than 50ms, supports full-format HDMI audio, and fully meet the audio-visual needs of high-end customers. Is an industry-leading solution.
This kvm extender can also be freely grouped and matched by dial switches (up to 32 groups can be divided), so as to meet customers' various complex networking requirements.

I use tons of these. However IF you’re bouncing them through a networking switch. Make sure the switch can handle them.

This product just does not work. I was unable to get both parts to communicate through my switch like the description says I should. In fact, this product doesn’t work for anything except direct connection to each other. Very disappointed.

I really regret purchasing this system and even more regret not fully testing before the return period was up. That part was my fault.My use case: I have two head3dless servers in a computer rack that I needed to have keyboard and video connectivity when changing bios settings, repairing OS, upgrades, etc. Having some experience with KVM extenders in general, I am a little leery of trying ones I have had no experience with but needed one over IP so decided to give this one a try.The POSITIVE: The receiver and sender did see each other quickly and connected without a problem. I am (was) using this KVM extender through a Cisco POE switch on a dedicated VLAN (with POE for power) which all worked fine as well.The NEGATIVE: As mentioned 99% of my need for this system is only to see the BIOS screen, POST info and Linux and DOS based boot (USB) drives to run diagnostics/ upgrades, etc. And this is where I have had a miserable experience.The first server I tried it on was a Ryzen based system (with a GeForce GT 710 1GB dedicated only to this video requirement) and running Proxmox. On this system, I could not get ANY intelligible video (just video noise) at any time- POST, BIOS, etc.The second system (also Ryzen with the same video card running Proxmox Backup OS) is almost as frustrating! The screen will NOT stop blinking on and off no matter what I try! I have rebooted many times, reset the extender many times, tried other configurations, in BIOS, DOS, Linux but still it keeps blinking. Sometimes it loses the keyboard but always keeps f-ing blinking so much it is hard to do anything, much less how crazy annoying it gets.And it doesn't help that the documentation is so ridiculously basic and so little detail that it is no help with troubleshooting any issues!I'm not sure how it works with a "standard" video signal but BEWARE if you are trying to use it like I am.

This is a good product. It does what it says it does.

Used this to remote the 4K monitor on my Lorex NVR with 4K HDMI output. Initially had issues trying to get the boxes to connect to each other when I ran them through a PoE switch on their own VLAN. After trying a few times via the switch, I directly connected them to each other with a single CAT6 cable and using the supplied power adapters and they quickly linked up.I then moved them back to the PoE switch on an isolated VLAN and they were able to link up just fine. Has been reliable for the last few weeks with no hiccups.PRO TIP- You really should put these on their own dedicated ethernet cables to each box. Do not share the cable bandwidth with other computers, etc. Why? Because these boxes are using about 800 Mbps of bandwidth at 4K 30FPS. 1080p doesn't drop the bandwidth much (uses 650-700 Mbps).-----UPDATE 10/20/2022-----This is a followup from my original review on 1/8/2021. Happy to report this 4K HDMI extender is still going with no issues so far. Both sender and receiver are connected to a PoE gigabit switch (wall warts not being used). Used in 4K30 mode with a mouse for a camera NVR.

I tried it with two of my 4k display and two HDMI sources; as I can tell the UHD mode (4k@30, 444) mode can't pass this extender, it changes EDID content so it limits to 1080P (HD) modes. The pictures shows the Apple 4K HDR adapter shows 1080P and 720P modes. The CEC also not working, could not use one remote to control multiple devices. I used it with 80M, Cat6 cable without problem for 1080P and USB together. The users manual is not clear at all, you may need to guess or try it to get a feeling. The build quality is not that impressive, consider this is a $160 of product, I expect it should deliver better.Overall, if you intend to use it for 4k video then forget it, don't waste time on it.

I have one device plugged into a server in a closet. That device plugs into the network. Then on the other side of the facilities 3 network switches away I have the receiving end plugged into a monitor, keyboard, and mouse. I can now control the remote server. Screen refresh is decent enough for non-animated work. i haven't tried to stress test it yet - don't really have a need to.It's POE as well so I didn't need to use the included power adapter. Very slick.Ordering a second set for use elsewhere.

I had some 1080p HDMI to Ethernet adapters for bringing the video output from my security camera NVR (in the basement network closet) upstairs to my living room television. When the transmitter died, unexpectedly, I bought these units to replace the dead ones. I can see my 4K cameras so much clearer. The quality is amazing and there seems to be no latency or image ripping. Plus, if I need to pull video, I can plug-in a USB key right here, and not have to go to the basement. I might have to buy another just to play around with. Very happy with this product.
