The Amimon Connex Wireless HD Video Transmitter was designed for Professional Drone use, but with a modified kit from Camera Motion Research you can use it to transmit the HD Video from your HDMI over 3,300 feet (or 1,000 meters). The video transmits in full Uncompressed 1080p up to 60fps with what they say is zero latency.
The Amimon Connex kit from CMR has been modified for ease of use with your video cameras by attaching a custom battery pack frame to both the transmitter and receiver, includes modified power cables, and also adding 1/4-20 threaded mounts for mounting to a hotshoe or rig (among other small accessories added to the kit).
Even though this particular Connex kit has been modified, you can always remove the battery mount if you want to use it for your Professional Drone. For those who aren't familiar, Amimon chipsets are licensed to other big brand wireless video transmitters (i.e.Teradek), so they are proven to be reliable and robust. The value in the Connex kit specifically is that it does lack SDI inputs and does not transmit Audio. This system is for HDMI use only (but you can always add an SDI to HDMI converter).
Amimon Connex Wireless 1080 HD Video Kit
So if your project relies heavily on transmitting video across long distances in full 1080hd up to 60fps, the modified Amimon Connex from Camera Motion Research is a great option for professionals. There are some additional accessories for this kit such as D-tap power cables and you can find more information at https://CaMotionLLC.com (here)

@andy -- Could you elaborate on what you mean by ‘broadcast environment, with bolts everywhere’. Do you mean other Teradek Bolts, or other wireless 5 Ghz devices being used in the same vicinity?
The Connex has a capability to operate with up to 6 other Connex’s, or presumably Bolts in the same area, but range could be affected. How close are other units? Are the other units performing better than the Connex?
The Connex does not do a progressive to interlaced conversion of the HDMI signal fed into the air unit. Are you sure the A7SII is putting out progressive?

@Emm - I also like to know the findings to @Dustin's questions. I did like to see if there's any frame drop for running it into a recorder. I am trying to put today a cheaper system where I can transmit video to a recorder. Question: If I wanna add sound to sync and transmitted with the video, can you advice me on that? Will that just be like for example having a wireless mic on my talent and sending it to the recorder with the video?
Also the Connex set for $1599 that I see on the web site you provided, is it the kit that you're talking about? I didn't see anything about the batteries and case that you talked about.

we've been using this recently on your drone in a broadcast environment, with bolts everywhere, only managing get 300m out of it, kinda bit disappointing in all honestly. also only could get output interlaced out of a7s ii shooting in 4k

Post author@carlos d - It may not be obvious but I guarantee there is latency on the Nyrius consumer version. Some have latency so bad it's unusable. The consumer versions are cheaper because they most likely don't carry the same frequency hopping tech that the high end stuff does to ensure it's always a clean signal. Especially if you are working indoors with obstacles that can obstruct line of sight. Also i've used some consumer versions that will work on 23.98 but not on 24p. Let alone higher framerates up to 60p. The consumer HDMI stuff is great when on a budget, but this Amimon is just another option when you need this type of range, little to no latency, and support for a variety of framerates. Stuff like this can be important when working with live switching stuff like broadcasting where you switch between multiple camera angles. I guess alot of this most people may not ever run into, but if you've worked with different tools, eventually you notice what features some of the lower end versions lack.

years ago i shot a shitty movie. I bought a consumer hdmi transmitter and it worked with no delay.
if i wanted wireless video today, id probably get a newer one, on amazon im seeing Nyrius ARIES.
I think the transmitter gets power via usb. Which is great because I have a dtap-usb on my shoulder rig. I don't understand these companies that charge an insane amount of money, when you can get something consumer and great. Unless if maybe you are shooting in crazy elements, but how many of us are shooting the revenant?

I'll definitely be looking out for you test. It definitely sounds like something that could work for me. I don't need audio, and HDMI is probably fine as well.

Post author@Dustin - I'll see what types of tests I can run, but this is the same guys who license their tech to other brands (as mentioned in article). From my experience so far, it's definitely a pro wireless video solution, but cheaper because the form factor was designed for Drone use and doesn't transmit audio. But now that CMR has added some needed parts, it can easily be used for camera work. I have a few shoots this week in which I plan to use this kit all day.

How does this handle dropped frames? I'm looking for a midrange wireless transmitter like this. Latency isn't a huge issue for what we're doing (running cameras in multiple locations into recorders at a central location), but we can't have a single dropped frame or our videos won't process properly. Could you possibly do a test to see if you're getting any dropped frames over a clip around 45 minutes?
