LKV373A 1080P HDMI Extender 365ft/120M Over Single Cat5 /Cat6 /Cat7 Ethernet Network and LAN Router/Switcher for HD STB,DVD,PS3, etc Supports TCP/IP by Ethernet

We used this for an overflow room next door to the church at a big event in our parish. The setup was HDMI from a video camera connected to the SENDER unit, 268 feet of cat5e connected to the RECEIVER unit and then to a LCD projector. At the receiver unit, we used a HDMI to VGA adapter that had the audio broken out to get the sound. The result was VERY good video in the overflow room with quality limited by our projector. If I was to buy again, I would consider the units that have sound broken out at the RECEIVER unit. This unit performed very well - exactly as advertised!

I purchased this to test its functionality, and it works as advertised, so I purchased two more. I was able to deploy this in a facility connect it to a computer, and then VLAN it through managed switches to the third floor of the building to a TV screen. Sometimes, we have to re-sync them when a network issue occurs, but that's rare and not the fault of the device. Just hit the sync buttons and you're good to go.

Don’t buy it! Wanted to send my 1080p NVR to two displays In my home through a 5-port Netgear unmanaged switch. Spent countless hours trying to get it to work. Kept getting an error to check my tx signal. Finally got it working after an hour of messing with resetting the tx rx devices, unplugging and replugging cables. Then I power cycle a tv, and get the error message again. Three days of messing with it. Still doesn’t work. Waste of time and money. Returning and ordering something that actually works.

A older version (2.0) of this product is being sold for almost the same price.Mirabox HDMI Extender Over IP/TCP Cat5/5e/6/6e Rj45 UTP/STP Ethernet Lan Switch Network Support 400ft(120m) 1080P Full HD Extension, Black (HSV373 A Pair)The product on this page is version 3.0 and it syncs more reliably than 2.0.Neither of the products work very well if you put them on your network. I spent hours trying different configurations on my home network and I was amazed at some of the havoc caused. The most interesting thing was the specific ability to complete disable router wifi transmission. I was able to do this to my xfinity gateway, as well as two different netgear routers (X6 and X8). This happened with repeated experimentation and the wifi broadcasting returned when i removed the extender from the network.Even though the device works, it fails for me because at times it renders my network useless.It actually works just fine if you want to use CAT5e or 6 cable to connect the transmitter and receiver directly.I also works pretty well if you connect it to an un-managed switch, rather than directly to a router. I don't know enough about networking to understand why this was case.My goal was to connect to it a router (or even a switch connected to the router) on one end and a high quality multi-band wifi-extender on the other end set up as non-broadcasting wireless access point and placed in reasonably close proximity to the router. Doing this resulted in a signal that constantly went in and out (85% out, with 15% flashes of low quality picture) despite measuring INTERNET download speeds of > 100Mbps from the ethernet port of the access point. Clearly though, I didn't have enough bandwidth to receive the transmitted HDMI signal.

There is a little lag time with these and sometimes I do ha e to reset the units. I have these running through a wireless router and they do really good. Overall good value and great device for getting hdmi to several TVs.

Works as advertised. Extending HDMI between floors for my daughter's TV. Syncs right up and looks as good as original signal. Highly recommend. Get yourself an HDMI splitter to have the original signal and the extended one at the same time.

Works as advertised and perfect video. The only problem is latency (maybe about 4/10 of a second). Not a problem if you're not using it for computer control (e.g. mouse or keyboard). Also, it sends 1080p signal regardless of source, so a 720p signal displays as 1080p on the receiving device, resulting in a small picture. This is not an issue if your tv/monitor has a zoom or fill mode; otherwise, you're stuck with a small picture.

I am sending a Security DVR video from work to my home, using my 10G backbone to my house several miles away. Turn on the home TV and I can see all my cameras from the office.
