HDMI Extender 196ft HDMI Over Single Cat5E/6/7 HDMI Repeater HDMI Balun Sender Transmitter Receiver Support 1080p 3D HDMI 1.4a HDCP EDID

So this technology is not odd, nor unobtainable. What's odd is the price point... which is probably about what an empty box shipped next day would cost.Here's my set up:I have a 1080P 3D projector in the basement along with a 120" screen, a nice receiver and an 8 channel setup. No one in my family will go down there... because it's the basement. We have a nice, finished, relatively comfortable, dry basement. In the summer it stays cool; in the winter it stays warm. I guess it's still a basement. Whatever.So I wasted tons of money on a home theater that no one uses... welcome to fatherhood... but there is a solution. Everyone loves our back yard, and so eventually movies in the backyard became a thing.Actually, I think, backyard movies became a thing because it is incredibly difficult to set up, nothing ever works, and I'm the only one who knows how to put it all together. I can bring the Apple tv outside and connect it to the projector, but the audio needs to go back down to the basement, as our backyard speakers are connected to Zone 2 of the home theater receiver. I can leave everything plugged into the receiver and run an HDMI cable across the basement, out the window, across the yard, to the very expensive projector. No one will trip over a 75' HDMI or a 50' extension cord when running around the yard, right? Everything works without a hitch over long cables, right?So further in the backyard is our garden area.... I'm getting to the review, hold on a minute. This area is lit with smart bulbs and has a somewhat complex smart system running various aspects of our koi ponds. This area, without going into detail, is wired for power, audio, ethernet and a few different smart hubs. I ran a backup unused ethernet cable in one of the conduits when I installed all this, and our main distribution switch is directly next to the projector in the basement. HDMI is already run from the receiver to where the projector is.I purchased this HDMI to ethernet set fully thinking this wasn't going to work. I plugged the HDMI out from my receiver to the sending unit along with the end of the spare ethernet cable. The other end of that ethernet cable goes across the basement, outside, and 70 feet across the yard to a waterproof box in our garden. Total run of ethernet is about 100', and it's 5e, not the recommended Cat6. This gave me an ethernet outlet about 6 feet from where my projector needs to be for a 120" screen using rear projection (so no one trips over the cables).I plugged everything in, and my mind started taking bets on how exactly this device would fail. The only thing that would have surprised me was success.I was surprised.Everything worked. 1080P 3D, 5.1 audio (verified on my basement receiver), stereo PCM, and HDMI-CEC. I didn't test any advanced audio modes like True HD because my outdoor theater can't really use that. I have now used this for about a month and have watched quite a few movies with this setup. I can't quite speak for the longevity yet, but if it breaks I will buy another one.I can now set up an outdoor theater in about 20 minutes when it once took a couple hours. These magic boxes work and save me time, money, and frustration... and now we're watching more outdoor movies.

Worked great

Bought this to replace a long run giant HDMI cable from our Den to our Dining area. I was cautious about this purchase because there seemed to be a wide range of positive and negative experiences in getting it to work. Initially I could not get it to work, but I went online and read the instructions for a similar product. The instructions that come with this box are not clear.Here's the trick to getting it to work. You must connect the Transmitter/Sender box DIRECTLY to the Receiving TV you're trying to connect to *FIRST* via an HDMI Cable. (not via ethernet.) (It's the opposite of what you would think you would do.)When Sender/Transmitter unit is connected via HDMI to the Receiving TV and powered on, press the button on the this sender/transmitter unit once *to capture the HDMI profile of the RECEIVING TV.* You may want to hold the button 3 seconds to reset it, then once to capture the HDMI profile.Then disconnect this Transmitter/sender box from the receiving TV.Bring the transmitter sender box to the other room and HDMI splitter your going to send FROM. Now connect the transmitter/sender to this HDMI splitter (it retains the information of the Receiving TV even when disconnected) , attach one end of the ethernet cable to it.Go back to the Receiving TV and connect the *RECEIVER* box to to the Receiving TV via an HDMI cable.Connect the ethernet cable and the power adaptor. It should glow red at this time.Go back to the other room. Attach the power adaptor to the Transmitter/sender box, making certain the ethernet is attached as well. The indicator light should glow blue/red = pink.The indicator light on the Receiving TV box should have changed from red to the same blue/red=pink. It should work.It's confusing and non-intuitive. Basically you're connecting the TRANSMITTER box to DIRECTLY to the RECEIViNG TV FIRST to get and save the HDMI configuration.I tested it with just Cat 5 patch cords, but my final installation was using Cat 6e. It seemed to work fine with Cat 5 over a distance of about 35-40 feet.
