OREI HDMI over Ethernet Extender over Cat6/Cat7 Cable upto 165 Feet 1080p, Full HD, Local Loop Out Option, with IR Control EDID POC Function Transmitter and Receiver (EX-165C)

getting the right cable was a huge and costly headache -- do not believe their claims of being able to work with cat 5 or cat 6 cable.what they claim to be able to do is to work with any cable that is rated for 1 Gbps and that they will overdrive it and push a 4.9 Gbps signal through it. perhaps for very short distances this actually works. but in reality these misleading claims produce a huge headache and an unusable quality of signal. specifically cat 6 cable does NOT work and don't even think of using cat 5.What does work is a 100 foot cat 6A or cat 7 cable rated for 10 Gbps. Once that was installed the 1920x1080 @ 60Hz signal was great.subtracted 2 stars because of the misleading claims that caused me a huge headache, I foolishly didn't take the extra time to set up a test because of the hassle involved of moving the computer, so instead I ran the cable through the attic and then had to go out and buy another/better cable and run that after I couldn't get the first cable to work.Further Note: originally I had planned to use a wireless system. But after reading tons of reviews I concluded that the wireless systems are unreliable and have poor quality images (the video signal gets compressed and degraded) and I only found one of them where people were happy with the speed. every single wireless unit that I read about (but one) introduces a perceptible delay between the source and the projected (remote) image. if your audio is taken from the source then this delay is unacceptable. that is the reason I chose to go with a wired system even though I really wanted to avoid the install.after reading tons and tons and tons of reviews. I chose this wired system and I am happy to report that with the correct high speed cable, this system works great. I was unable to observe any perceptible delays and the image quality is indistinguishable from a direct connection to the monitor/projector.installation Tips:1) If possible, test first before you run the cables through walls and attic etc.. I know it's a hassle to move the computer, but it is a much bigger hassle to have to redo everything.2) this uses some switches to set the signal strength. The thing is though that if the signal is too strong it won't work and if it is too weak it also won't work. and there is not any good indication either, which basically leaves you guessing. With a long cable, try starting at the highest strength setting and work your way down, with a short cable start at the lowest setting and work your way up. Set the computer (video source) to display a static image at the desired resolution. Although not strictly necessary, I found it helpful to cycle the power on the box every time I changed the switch setting (but see below for note about the power). and then wait for about 30 seconds to see if it succeeds in syncing. once I got a signal then I went one step further on the switches. so if you started with the strongest signal go down (weaker) by one more step. and if you started at the weakest signal, go up (stronger) by one more step. this ensures that you are not sitting on the edge of a borderline signal and are solidly in the zone.3) Power is weird but handy... if you look at the pictures, in a previous model, only one end -- the transmitter -- had a power plug (and supply), the other end did not. In the model that I received, both ends are powered and come with power supplies (aka wall wart). But here is the thing... this system uses POE = Power Over Ethernet. What that does is that it sends DC power over the same cable that is used for the signal. This is a Very Nice Feature. It means that you only have to plug in one side, either the transmitter or the receiver and both sides will receive power. You can also plug in both sides and that does not appear to cause any problems. But note that if you do this and you want to cycle the power on the receiver box you must unplug both it's power and the network cable, otherwise it continues to be powered over the network cable and does not do a reset.4) The pass through video (AKA Loop video) is very useful for troubleshooting and during configuration of the signal strength setting. the transmitter box has an HDMI Out that you can plug a monitor into. it also has an EDID switch. What EDID does is it allows the computer (or whatever) to ask the monitor what resolutions and frequencies it can display. the computer (or other video source) then selects a resolution that it knows how to support, from the list of available resolutions. But what happens when it can't get a signal from the remote monitor due to a faulty cable? chaos!!! that's what. So to avoid this mess, set the EDID switch to use the directly connected monitor as the source for the resolution info. then you will have a stable video output while you try various signal strength settings. Once you have it working, don't forget to set the EDID switch back to the remote monitor unless the pass through monitor is going to be permanently attached, otherwise the next time you cycle the power you will be back to chaos...Bottom Line: It was a pain to get this working, especially because of them saying it will work with cables that won't actually work (also the docs aren't great, but that is pretty typical). But once you get it running, it is a great system and worth every penny. We are very happy with it, even if I did have to crawl through the attic twice.Disclaimer: I paid full price for everything. I rely heavily on the reviews of other people. If you found this review helpful I would be grateful if you give it a Like. Thank You.

I first ran 100' CAT6 shielded and it wouldn't work. Cable tested fine. Disconnected one end of the shield, no signal. Disconnected both ends of the shield, no signal. Replaced the cable with CAT5e non shielded and it works great!

Our home has an existing home theater setup and after a few power outages, the projector was no longer recognizing the signal from the receiver. I tested both the projector and receiver and found the error was a failed balun. This is fairly normal. I considered running a fiber optic HDMI as the distance was under 50ft, but the cable routing of the existing CAT5e cables was too convoluted and difficult to access, I thought a $30 attempt at balun replacement would be a good place to start. Easy swap from a two cable to a one cable HDMI to CAT connection and it worked immediately upon replacement. I saw other reviews stating CAT5e support wasn't capable of handling the signal, but I had no issues. Great value for clear picture and easy replacement. Only gripe is the box was supposed to contain two IR cables and both were missing. Reached out to the seller and they quickly resolved it.

The short of it:1. Use a CAT7 cord2. MUST be at least 40' between the transmitter and receiverMy application: I am connecting my patio tv to my DISH Network recvr in my living room. The only thing separating the two is an exterior wall. I chose this setup because running a CAT7 through the exterior wall was easier than running a HDMI/When I first hooked this up, I could not get it to work at all...so I tried to contact tech support. After a day of searching and getting frustrated, I found an email address...and this is the only way to contact tech support - which is my least favorite meathod. I really like to talk to people..emails are so impersonal. Anyways, I digress.So I sent an email and waited...while my tv wasn't working.The next day, tech support replied to my email with a phone number. I called them. The guy I talked to was very nice and helpful. Long story short, I only had 16' of CAT7 between the transmitter and rcvr. Tech support told me I needed a longer cable because the signal was too strong and could not be decoded.The fix: I bought a 33' CAT7 (which gave me total of 46' between the boxes) and it now works as advertised.If I could go back and do it again (or if I would have know this to begin with), I would go with the HDMI setup.

This product is small and easy to hook up. It works as advertised and a great solution to extend your TV watching to another location.I used Cat 6 cable to run from a sun-room on the first floor to a basement exercise room the distance is about 30 feet, Cat 6 cable 35 feet. When I hooked everything up the picture was great but the sound was very intermittent and unintelligible. The small manual mentions picture quality and recommends changing dip switch settings on the circuit board depending on distance between the two units.I unscrewed the two small screws holding on the cover of the receiving unit, studied the switch settings graphic on the instruction paper and in a guess flipped the #3 switch down (all were up factory setting).Hooked everything back up and checked it before putting the cover back on and viola the sound was great, picture still great, upstairs TV works great, Dish Hopper remote works in the basement to control the TV. Totally happy with this product.

Stopped working after one hour of use. I have similar devices from this brand, and they seem to work well. Very disappointed with this unit.

Works every time we use it! Be careful if this isn’t a permanent installation to verify you have the correct power cord because it does matter.
