J-Tech Digital HDMI Extender over cat5e/6 1080P@200ft HDMI Balun Over Single Ethernet Supports EDID Copy Compatible with Dolby Digital DTS

I have been converting my home from standard TV to 1080P high resolution. The video source is in the garage (Roku), where the satellite and network feeds come in. All TV's (five different locations in the house) get the same video in my situation. Because there are spare Cat5e cables and coax cables in the walls of the house, finding J-Tech's HDMI extender products was a godsend. I have used them for HDMI - over - Cat5e (Cat6 and Cat7 would work too but my house is older than that) and for HDMI - over - Coax. Both work flawlessly. One of my endpoints is a projector that blocked the HDMI's audio (projector's fault), so I tried the J-Tech audio splitter prior to the projector and again, that works flawlessly. Three J-Tech product types, one happy customer, extremely easy setup all around. Here's another thing though: I had a few technical questions. J-Tech's customer support was awesome - they answered all my questions completely, clearly, and in less than a day. Thank you Jewel! My one suggestion to J-Tech is to upgrade their product manual to address questions like mine (specifically: can you swap transmitters or receivers? yes. Can you drive multiple receivers from a single transmitter? no. How should I interpret the status LEDS on the receivers and transmitters? transmitter: red is good; receiver: green is good) And whatever else comes to their minds to make the user's life easier. I think some of J-Tech's devices can work with 4k video, although as an engineer I have always been dubious that 4k is much more than a marketing ploy compared to 1080p; the human eye is not that discerning except under closely and continuously monitored conditions.

To be fair, I have now used this device exactly 6 times. So long term reliability? I can't speak for, or against, that. But at a recent funeral for a relative, I needed to send an HDMI video from my Canon camcorder (Canon VIXIA HF G20) to a nearby building, where overflow crowd was being put, since the main building would be over capacity. Audio was handled via wireless mics, no problem, but sending a 1080p video feed was another story. I ran a 20' HDMI line from my camera to a projector, as a test, and everything worked perfectly. So I tried a quality manufactured Belkin CAT 5e 100' cable, using the extenders, and again, it worked perfectly. My concern, of course, was longer distances, since I would be operating near the maximum stated spec for the extenders... much more of a challenge than the best-case scenarios I had just tested. A couple of days later, when my box of cheap CAT 5e bulk cable arrived from Amazon, I dutifully measured out a 300' cable (the distance I needed the run to work) and crimped connectors on it. I coiled it all up, and plugged everything together, for a close-quarters test. Imagine my dismay when it did NOT work! But looking at the large coil of network cable, it occurred to me that "cable loops are bad" or so I've always been told. They just never seem to matter, to me ... at the short distances most normal people work with. But this was a relatively extreme setup, so perhaps one more test? I took the long cable on a long walk around my backyard, eliminating any loops in favor of a straight run, much like I would have in the final installation. Plugged it all in again, hey, it worked! There was much relief. On the day of the event, we set up the camera, and ran that same 300' cable over to the next building (all connected through hallways), taping it down and cleaning it all up neatly dressed. Plugged the camcorder into the transmitter one side (via 6' HDMI cable), plugged the projector in the receiver side (via another 6' HDMI cable), fired it all up in sequence, and what do you know! The picture came up perfectly, just like with the shorter, easier tests. The event came off flawlessly, without a single hitch, thanks to this little gem. So even if it dies at some point in the future, I'll always be grateful that this important event came off perfectly, and everyone in both buildings was able to see the ceremony easily.

I purchased these in November to replace some other HDMI extenders that I had been using that used two CAT cables and had failed. I liked these since they had power at both the transmitter and receiver and figured that would lead to no issues with video signal dropping out. I hooked them up and they began running immediately and worked fine. In the past couple of weeks or so, the video on the tv at the remote end has been dropping out intermittently. Usually it would only go out for a few seconds and then reappear. However today, the video has failed totally. I reset everything but still cannot get them to work and figure they have failed. I am just beyond the return date for Amazon, so now I will have to work with the company to see if they will do something. The status light on the transmitter end remains red which I don't believe is good.... Edit to original post: Contacted company directly and they sent me a replacement. i have hooked the replacement up and all is up and running again. I hope that failure was just a bad component and the new ones will run for a long time. Changed my rating to a 4.. probably would be a 5 except for the failure. Update: Called Tech Support and they are sending out a new pair. I will be down until I get them, but it was no hassle. I will update after I get the new pair and if they work chalk it up to bad luck and raise my rating.

Need to buy HDMI to Ethernet converter and Ethernet to HDMI converter as a pair

Sadly this product does not appear to used standard IP data to comunicate between the transmitter and the receiver units and will not work on a standard home network as I was hoping it would. it does however, work well as an extender with good quality HD pictures & sound. I would be happier with the Amazon page listing this product if it were made clearer which protocol the extender used, so that the buyers would know exactly whether it could be used via an ethernet LAN system or not. Both transmitter & Receiver units feel solid and well made and work well provided you can run a single dedicated cable between them.

距離は20m（LAN）+12m（HDMI）程度の延長でしたが、他の製品ではことごとくダメだったところ、本製品だけ正常に映像が出ています。 使用しているLANケーブルが諸事情によりCat7ということもあり、他製品は相性？だったのかもしれませんが、助かりました。 ノイズやチラつきも全くありません。

届いたときは何をやっても表示せず焦りましたが、問い合わせるとすぐに対応していただき問題なく表示できました。 送信機を直接テレビにつないでからボタンを押すと初期化？できるようです その旨の説明書か商品説明があればスムーズかとは思います
