To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I suppose I was a bit naive to think this could transmit a signal through a cement block wall, but it was only about 10 feet. Based on the description, you would think if it's strong enough to transmit 200' (line of sight) it could go through a wall if it's only going 10 feet or less. But, it will also not transmit around corners. Essentially my setup was a TV that was around the corner, through a door, where the transmitter was only 10' from the display and it still wouldn't work. Not even with the door open. The ONLY time I could get them to work is if I moved the transmitter to line of sight from the display. So, if you're buying these to transmit a signal through walls, then you can try it - but it may not work. Some of the reviews indicate people transmitted them through drywall & rooms away in a house & it worked, so I thought it was worth a try. I had to return it because it would not work for my application; the return was seamless. I give 3 stars for build quality (metal, seems high quality), service, and if it works for your application-then great, it didn't for me.
I really wanted this product to work and did a lot of research on comparable HDMI Transmitters. It worked ok in the beginning but the latency in the Audio was so far off it was annoying to watch most programs. Every once in awhile the receiver would loose connection with the transmitter in the middle of a program. Very annoying! This unit is rated for 150ft but they were only separated by 30ft. I shortened the distance to 15ft but it didn’t make any difference. The loss of connection grew worse every week so we returned it before our 30 day deadline. Will research another product and hope it works better.
It works. Easy to install and operated out-of-the-box. I am using these to show the security cameras (1080p) in a different room. The distance Tx to Rx is probably 25 feet through 3 (interior) walls. The image quality is not as clear as I feel it should be. Compared to a monitor that I was using that was attached to a 30' physical HDMI cable, (in a different room) the image there was a 10, on the wireless it is a 7. It is acceptable in my application, but if this were a TV channel, I would not be happy with the image quality. Aside from video quality, the main issue is a reset function that does not work correctly. The security system does an automatic reboot once a week. Whenever it does, the signal is lost and can only be restored by physically unplugging the cable that runs from the back of the security DVR to the Tx device. That does restore the signal, but it is a pain to have to do this each time. I haven't tried, but I suspect the same issue would happen if power were to drop then restore. It should be able to handle these common issues.
I bought this along with an HDMI splitter to share a cable box for my living room TV and my bedroom TV. The splitter works great but the wireless has some issues. While watching sometimes the picture drops for a second (maybe once an hour) and sometimes the sound gets jittery (this doesn't happen very often) which is fixed by pushing the reset button on the sending unit. The IR remote control extender can be frustrating and works poorly and is the main reason I gave this a two star rating rather than a three star rating. It is very difficult to control the cable box with the remote control as there is frequently no reaction when pushing a button on the remote control or the button shows as pushed twice. When you are settled on a channel it works pretty well which is why I didn't send the unit back. The other reason I didn't send the unit back is because I don't use it nearly as often as the living room TV.
I intended to use it to connect cable box to 2 TVs in neighboring rooms. However on opening the box I found that it may connect to only one TV, because there is no pass through Output HDMI on the transmitter. There is no picture of the back of transmitter , otherwise I wouldn't take it. For those who use it simply for remote trasmission of HDMI to one TV it may be perfect, but not for my purpose. It requires purchusing a separate receiver for $119 to connect a second TV. It looks like intentional hiding of this important fact. I returned it the same day after receiving.
This unit works great when its working, the problem is it periodically loses it's signal. When that happens I have to disconnect the power to the transmitter and plug it back in to get it to work again. Sometimes it will work all day with no problem. Sometimes it disconnects 4 to 5 times a day and each time I would have to unplug and plug back in the transmitter to get it to work again. I thought that for the money I paid I would get something more dependable.
This is my second go-around with a digital HD transmitter. The first one I used, ActionTec, worked great for almost two years but lost its ability to receive the HD signal. So, I purchased the J-Tech Digital HDbitT Series 1X2 Wireless transmitter to replace the ActionTec. For the first couple months, no issues. About three months in the receiving unit kept cutting out and losing the reception from the transmitting unit. For some reason, the receiving unit had trouble getting the signal even though nothing changed. We kept trying new connections, restarting both units, different HDMI cords, etc. It wasn't until I moved the receiving unit away from a 2nd wall that is started working again. Apparently, two empty walls on the same floor, is too difficult to transmit through.
Overall, the unit works well when there are limited obstructions. Right now, I have the receiving unit located 10 feet from the TV so it is in a doorway while the TV is behind a wall. Have a handy extra long HDMI cable ready if you purchase.
The range is good, picture quality is good, but I could not use it to stream HD or 4K video, it's lagging and stop.
My main purpose of buying this is to stream video from my surveillance camera system DVR to my living room TV without having to run cat 6 wiring, but need to reset it once and awhile to get video image.
Unit has to be tuned off and back on EVERY time it is used. Ie. If the unit is on, and Direct TV is turned on, unit had to be turned off (unplugged) and turned back on. Otherwise tv will display a "no signal". I resolved this by installing a remote operated power out.
I have it going from the front bedroom to the rear. I had to leave the receiver towards the door in the back bedroom because my bathroom wall is real thick. its like 4 inches of concrete. but works great
Updated. They don’t last longer then the warranty period. It sux because they’re nice when they work.
