Updated 8/3/2023: Was contacted by the vendor with updated pairing instructions. Finally uninstalled the unit to execute the task. Basically, the steps: 1) Everything is powered off - Power on Transmitter and Receiver. Wait 5-10 seconds. 2) Connect Transmitter and Receiver via HDMI cable for 5-10 seconds. You are now paired. You can now disconnect the device and put them in their homes. Note that I did this with the transmitter staying in the same location. Also, I happened to have a portable HDMI monitor so I plugged it into the HDMI Output port so I could see that it assigned an Infrastructure IP address.Once I did that, I plugged the transmitter back into the A/V receiver (the video source) and the portable monitor into the receivers output port. The image was syncing correctly. Once that was complete, I reinstalled the unit on an outdoor television.No idea why they became unpaired as they do not connect to my wi-fi network.Updated: Downgraded to 1 star. Initially worked out of the box - no longer connects at all. I have made attempts to contact support through their website and email, nothing but crickets. I will try for another day to get this to work - or it is going back. I love the functionality of what it is supposed to supply - so I will be looking for a similar item - and hopefully with better support.--- Original reviewI installed this to broadcast from my home theater setup to an outdoor TV. Our home theater has Zone 2 outputs so we have speakers installed outside which sound much better than the TV speakers. Watching the same sporting event inside and outside led to a delay of a few seconds (with the same streaming platforms)..This allows me to broadcast the main video signal from Zone 2 to the outside tv while pushing audio to the Zone 2 speakers.I can even drive my Amazon Fire TV cube from the patio with the remote now!Be careful, the antennas on the boxes are very fragile - the only reason this is not a 5 star review. Will eventually buy another receiver for and outdoor projection screen!Updated - After a month it just quit working. Will not pair up... have reset receiver and transmitter as well as power cycled them. Waiting on support to respond.

Product works as described. Once the TX and RX sync the picture and sound quality is very good. The only issue I have is that the signal periodically drops and has to re-sync during the first 5-10 minutes. I do not know why. However, after a few minutes of operation, everything seems to settle in and no dropouts are then noticed.

SEE UPDATE BELOW: I bought this receiver (RX) to pair with my TX/RX configuration that I already had and was working pretty well, and was supposed to support up to 4 RX. After several failed attempts to pair, I contacted the manufacturer directly through their website. After many email exchanges and trying different things and sending screenshots, they acknowledged the problem and said they had a RX that should pair and work and they would send it to me. After several days, I got a package from them, but it was a transmitter (TX) instead (which, by the way, also would not pair with the RX). I emailed them about the apparent mix-up, and they ghosted me. So I sent the RX back to Amazon, still deciding whether to keep the TX/RX since I cannot add another RX. If you want to be able to support more than one RX, don't waste your time. Read the reviews. I gave them one-star because at least for a while they acted like they wanted to help.UPDATE:I finally got another RX from the manufacturer and successfully paired it on the first try. They provided different pairing instructions from what is on their website and in the instructions that come with it.- power on both the TX and RX before connecting the HDMI cable. Wait 5-10 seconds.- plug the HDMI cable into the port on the RX and the IN port on the TX. Wait 10-20 seconds.- doneI now have 2 RX working with the same TX. Hoorah. I've updated the review rating. Couldn't give a 5 because of the hassle factor, but I am pleased that Jack got back to me and got things straightened out.

I purchased the Mirabox Wireless HDMI Transmitter and Receiver Extender 1x4-200m(656Ft) 5.8GHz 1080P@60Hz Wireless Audio Video Extender Kit with IR and HDMI Loop-Out for TV,DSLR Camera,Projector,DVR,Laptop,PS5,Switch, in January, last week it quit transmitting or receiving. I attempted to contact the company Mirabox, without success. All it is now is a paper weight, just want some technical support or assistance.DannyFinal was contacted by Jack, from Mirabox. They replaced the Tx box and the Rx box. I tested both and they work great. So far, no other issues. Thank you, Jack. The only suggestion I would make, is to make it easier to contact technical support. The product works great.Dan

Using this to share the cable box with both my living room tv and my bedroom TV. Only thing to note is there is about 1/2 a second delay.

防犯カメラの2台目の追加モニターにNVRからケーブルを延長して使うために購入しました。30mのLANケーブル(CAT6)でしっかり映り映像が乱れることもなく満足しました。モニターの間にVGA⇔HDMI変換アダプターをかませていますが問題なしです。あとは耐久性がどうか運用を続けてみます。

ok

Work as expected. I have a transmitter running to a switch and from there going out to two different receivers along cat6 cabling. The furthest cable run is about 80 ft. Video feed is great.

2回程ですが購入してます。動作に何ら問題ありません。cat5eケーブル1本で映像を延長できるので良い。

The product is expensive but excellent
