These were one of the only options that made sense for 4k video that I needed for security cameras I can't notice any lag and the image quality matches the source as well enough that I can't tell a difference. took awhile to get it to connect but its been running for weeks 24/7 no issue and these dont get hotter than normal devices from my experience Like most transmitters do.

I tried twice. First delivery never could connect, reset and still no connection. 2nd unit received connected on first power up but receiving signal was green video. On third test no connection. The idea is cool but not reliable and from my limited test was low latency I had all of my audio synced.

Rock soild does its job. Using for baseball games and man Ole man couldn't be happier. No need for a wifi signal just any camera with a hdmi port than back to your video switcher than sit back and enjoy the game. Will say one thing if using multiple (which i do x4) better number the pairs keeps it easier for set up.

Excellent service. I had an issue with the transmitter and the company responded immediately, sending me a new unit to replace the defected one. I've used these on a number of film shoots with great results. The image is crystal clear without any interference. Very little lag either.

I wanted to test some HDMI transmitters because the idea is pretty cool.
This pack has a case and a transmitters / receiver pair. They are 1.2" x 2.6" x 4.5" without the antennas, adding the antennas adds another almost 2" making the unit 6.5". The have the option for a battery pack, but this set doesn't come with those. the body of the units has a 1/4" thread for a tripod/mount on two sides. The antennas must be removed to be put into the case.
These are pretty cool. My use case was that i wanted to watch a movie from my xbox but that is in another room on the other side of my house. I was able to plug this into my xbox and play a movie to my TV in another room without issue. There is definitely some lag in there, so gaming would be tough (maybe turn based). The audio and video were only the slightest bit off, which didn't bother me while watching a movie.
What i wanted to really test was the range, being able to use this on a projector outside could be cool. So got in my car with my laptop connected to the transmitter. I connect the other side to my tv and put a camera to watch my tv from my phone. The transmitter was able to send a signal from my car through the wall of my house to the tv from 140m or about 460ft, and that is impressive.
I like how the units feel (the top is metal (probably for cooling) and the sides are palstic. The 'industrial' look is cool and the case is a nice touch. I like that they use USC-C for power.

These wireless video transmitter receiver set is awesome! This set is quality and has great range. I love that it also comes with a fitted vase, but you have to take it apart to pack it away (such a bad design choice). I love that this will run off of my batteries and has a loop out function so I can use it on set. This is easy to connect and to mount, although I do wish it had more mounting points and connection types (like some cold shoe mounts). But this looks professional and works well. I love the status lights so I can see connectivity and battery life very easily.

This wireless HDMI transmitter and receiver can project the screen of a laptop, PC, PS4/5 , a camcorder, set top box, video player and others onto a big screen, monitor or other screened devices. Upon opening, I was slightly confused because the instructions tall about using the battery pack for it's main source of power. But this set doesn't include the battery packs. However you can plug this into an outlet. You also need to have HDMI cords going from both the receiver and transmitter to the device you are using. Funny that this is wireless but there are so many different wires required. It does project in real time with a high quality picture. They can be used for many different functions, it cannot go from TV to TV. Setting up isn't too bad either. They are small and have short antennas. They are in a high price range but do support 4K.

I intended to do a much more detailed review but these are so simple there is no need. They worked flawlessly right out of the box. I have an RGBLink Mini that allows for 4 inputs. I use it for live video switching during a video podcast I have. I also use them for Zoom business presentations when both my wife and I present topics together. This wireless HDMI transmitter allowed me to run a 4th camera from a different room without having a 30' HDMI cable. I tested it during an informal meeting and wanted to show the snowstorm in the greenbelt behind my house. It took me only moments to set everything up.
The receiver has an HDMI out which plugged right in. It immediately broadcast a "no signal" message which told me instantly that it was working as it was supposed to. I hadn't turned on the broadcast unit yet.
I plugged the broadcast unit into a Sony handycam and it broadcast at full resolution just about instantly. There are ports to allow it to transmit sound, too. Sound is a different input so you can use it with a different mic setup if your camera and mic are separate. Both units have 1/4" screw ports for mounting to your setups. There are also battery pack spots if you need to use this in a truly wireless configuration. I didn't. It does not come with batteries but they look pretty standard.
I couldn't be happier with these. It looks like it is an expandable set to allow for several sets of cameras to broadcast to the receiver unit though I'm not certain how it would select which images to receive. That's an issue for the expanded set that probably also works really well and easily.
Overall, I couldn't be happier.

The one expectation was important to me but probably not others, hence the 4-star rating. The User Manual clearly states: “TX Input: 4K@30Hz BACKWARD COMPATIBLE”. In HDMI terminology, “backward compatible” means it supports prior versions of HDMI signals. Reality: The TX (transmitter) ONLY accepts AND transmits 4K input – it will not transmit “backward compatible” lower HDMI video (sound only). The TX HDMI LOOP OUT will copy ANY HDMI input to the TX LOOP output port while NOT transmitting the video (only sound). Basically, it recognizes older HDMI input signals and passes it though the HDMI LOOP out but will not transmit them. The RX will connect but report “NO SIGNAL” while receiving and delivering sound to the monitor.
To be clear: It will transmit sound but no video signal when lower than 4K input. My satellite DVR and my VHS/DVD recorder/player output HDMI 1.4. The BovBox works perfectly with 4K HDMI input (see TESTING below) and this is regardless of using v1.4, 4K or 8K cables. Other than this discrepancy, the TX/RX system works as advertised on the product webpage so I will try not to be too redundant with the details.
DETAILS:
--- You get: Great storage case with handle, 1 TX, 1 RX, 2 USB A-C power cords, 2 USB 5V/2A power adapters and a comprehensive User Manual. HDMI cables not included.
--- The units can be powered using the USB cable + adapter, the USB cable into a PC or TV 5V powered port or with NP-F series chargeable battery packs (not included).
--- The TX can support 1 to 4 RX units. (see TESTING below) 1 RX 820 ft, 2 RX 328 Ft, 3 RX 164 ft, 4 RX 66 ft – all UNOBSTRUCTED.
--- Each RX unit has 2 HDMI output ports. Therefore, with the TX loop out and 4 RX with 2 outputs each = 9 HDMI output monitors maximum.
--- Both the TX and RX unit HDMI output is 4K@30Hz/1080P@60Hz. Many video and audio formats supported (see User Manual pic).
--- Both the TX and RX units have an audio jack for speakers, sound bars, headphones, etc. This is in addition to the HDMI output sound.
TESTING:
I have 4K splitters and 4K switches as well as v1.4, 4K and 8K cables and other HDMI 4K TX/RX sets which work with my old satellite DVR and old VHS/DVD player, and which are “backward compatible”. I do not own a cellphone or digital camcorder, so I was unable to test these sources.
The tests below were done with HDMI 1.4, 4K and 8K HDMI cables. The v1.4 cable ONLY worked on the old PC/Laptop test (both sound and video) and the modern 4K DVD player tests (same results), but on the old satellite DVR and old DVD player devices, I got only RX sound and “NO [video] SIGNAL” but the TX LOOP out worked on all 3 cables on all devices – I am not tech savvy enough to explain why it could transmit a 4K signal from a v1.4 cable but not a pre-4K video signal on any cable (sound only ???).
--- Old PC/Laptop: The BovBox system worked perfectly by transmitting to a remote LG flat screen from the living room to the kitchen, about 40 feet away through 3 walls. The picture and sound were perfect, no apparent lag or sound distortion. Almost instant plug-n-play connection. It did not matter which one was powered or plugged in first. The PC USB port provided sufficient power to run the TX unit. The included 5V/2A power adapter worked as well.
--- 4K Splitter and 4K Switch: The TX LOOP output sent a signal to the local LG flat screen but the RX reported “NO SIGNAL” but provided sound to the kitchen TV.
--- Direct connection to old satellite DVR: Good TX LOOP output signal but RX “NO SIGNAL” but sound.
--- Direct connection to old VHS/DVD player/recorder: Good TX LOOP output signal but RX “NO SIGNAL” but sound.
--- Direct connection to modern 4K DVD player: Good TX LOOP output signal and good RX reception video and sound. The same results when using the 4K Splitter and the 4K Switch connected in series.
PS: This test was done with 2 4K DVD players (one in each bedroom). I was hoping that I could use the BovBox system with 3 RX units (kitchen, master bedroom, daughter’s bedroom) by plugging in the TX to my 4K Splitter.
--- The TX and RX units worked with HDMI 1.4, 4K and 8K cables – input and output.
*** The only deficiency was that the TX would NOT transmit a 1.4 video signal. OK, it is a 4K transmitter/receiver but “backward compatible” meaning older signals should be handled for all functions. The TX does pass through the v1.4 signal to the TX loop out and the RX does receive the sound. 1-star rating drop
