J-Tech Digital Wireless HDMI Extender 1080p Transmitter & Receiver Kit Auto-Select Frequencies with no Interference, up to 660 ft and IR Remote Extension (up to 5 Pairs in 1 Area) [JTECH-WEX310]

Bought this on a last-minute job for sending funeral video live stream from the church hall, to the parish hall (overflow video scenario). It’s about a 250-300 foot run, as you can see from the two attached photos to give you an idea of the perspective/distance I’m working with. These units work really well, provided I have line of sight. The transmitter is located in the balcony of the building in the distance, to the right of the center pole of that white cross on the front. There’s a window there, and the transmitter is propped up inside it, so it is shooting signal through the window, through that cross grate, and all the way to me over here about 300 feet away. I’m pretty impressed. Signal has been rock solid. It only drops out if the vehicle passes directly in front of this window, etc. I like that this thing synced up instantly, with no extra buttons, hassle, etc. Just immediately found the signal from my camera and started transmitting. Well done, J-Tech!!!

Bought this two years ago and it stopped transmitting audio within a couple of months. Got a replacement and now two years later the same thing happened and they won't replace it. The warranty is only 1 year, but clearly the units have a major design flaw or component reliability problem. I used it only once a week for a couple of hours.

Sure, line of site. But through walls? NOT! Back to a cable solution.

I was very easy to set up and it paired automatically. I run it from my DVR to my projector about 30 feet away with no barriers. I would give it 5 stars but within 2 hours of use the sound went out twice. There was still a picture but no sound. To fix it I had to hit the reset button and it re-connected. It remains to be seen but I am afraid as the distance increases it will happen even more frequently 5/2018 The unit is 5 months old and it worked great until today. I turned it on and there are lights as if it is functioning but zero output. Way to expensive to only work 5 months. I used to have cable wirelessly link to my garage. It was used infrequently which makes it more surprising that it stopped suddenly.

Have two of these for different uses. One transmits through many walls including masonry fireplace to indoor and outdoor TV. Make sure you get the one with longer range and two antennas. Works great.

Transmetteur wifi pour sources et récepteurs HDMI très efficace. je travaille dans un cinéma et pour en avoir essayé d'autres modèles, je trouve ceux-ci très performants pour projeter des contunus HD d'ordinateur. Très bonne communication avec l'équipe et livraison rapide, si on prend en considération qu'il traverse l'atlantique... Je recommande.... Attention tout de même au prix qui se voit augmenter quand on ne vit pas aux états unis.

I purchased this item because my HDMI cable broke and it is inside the wall. Can't fish it out and replace it so my only option was to use a Wifi HDMI extender. This kit will send 1080p signal with sound from one unit to another without loss of quality. I have my transmitter in a closet in one bedroom with the cable box, stereo receiver and DVD player. The HDMI receiver is in another room about 20 feet away. The transmission of signal and sound are great. Here is the catch. It has to be from one appliance to the TV. If you want to use the transmitter connected to a stereo receiver so you can have multiple items connected to the transmitter and have surround sound then you have problem as there is lag between video and sound. Even with the Lip sync on the receiver. So if you are going to just connect the transmitter to one signal then it is great. My rating is based on that caveat. If you are looking to use it with your received so you can transmit different signals then it is a 1 star.

Simple installation and is working perfectly. Very satisfied with the product and the customer support.
