J-Tech DigitalHDMI 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.

I replaced a 60 foot (40 foot + 20 foot) HDMI cable which was working mostly but would occasionally stop for a few seconds with the J-Tech Digital HDMI Extender over cat5e/6 cable. I now have a solid connection to a TV that is located 60 feet from the source. I now never see any signal loss. Great product.

Works well. Sound quality is great.

This product worked stated. The only miss here was I wanted a USB-C extension and it only has a HDMI output. It was simple use and easy to setup.

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 can't begin to describe how unhappy I am with the J-Tech Hdmi extender products. This is the 3rd model I have purchased. It lasted only a few months before failing completely. I've tried this unit with multiple sources, televisions, monitors, and all lengths and types of CAT6 cabling. It worked great when I initially installed it, just like the other devices I had purchased. I'm using the extender to add a television as an extended desktop on my PC. I have an in-wall cabling installation using Belden CAT6 cabling with high quality CAT6 keystones. The entire cable run was less than 25 feet. I installed new cabling several times in an attempt to give these devices the benefit of the doubt. It's not my cabling, as I've tested and confirmed the runs multiple times with a Fluke qualifier. I see the same results with high quality premade CAT6 cables of multiple lengths.This device was primarily installed to keep cabling from running across the floor. This was my last attempt at using these devices. I'm giving up. I've had an Hdmi cable running across the floor for several months now to directly connect the components. Unlike the J-tech, that installation has been rock solid. I wanted to be absolutely certain it wasn't my equipment before I wrote a review. I've finally decided to just purchase an in-wall rated Hdmi cable and keystone ends. I should have just went this route in the beginning, but the CAT6 cabling was already in place.
