Just wanted to share we recently bought an amimon connex wireless video device. It's used to send HD video from drones up to 1 km (line of sight) away. the video is uncompressed, it adds no visible delay (1ms). The device works on 5.8 ghz, and can be boosted with better antennas or range boosters.

We tested it twice last weekend with stock hardware:

- The first test was in a venue where video had to be sent to a different room on another floor. There were 3 concrete floors and 5 meters between transmitter and reciever. We used the connex via the external output of vmix over an intensity pro card. We had no problems at all :)

- The second test was on a boat, where we left more then 100 meter between the transmitter and the reciever. We had people walking in between the transmitter and the reciever and perfect quality all the time. Here we used an XHA1 with a component to hdmi converter. We tried to use a decklink mini monitor to input the hdmi into vmix, but it didn't recognise the hdmi signal. We then used an intensity pro card and had no more issues.

Next week we will test it on a range of up to 300 meter, I expect no trouble at all, since we will have line of sight all the time.

For other gigs we will pimp the device with new antenna's and 5.8 ghz range boosters, in order to pass LED walls and bigger crowds.

The device costs 1800 euro, this is a steal compared to Terradek or Paralinx products, who are also powered by amimon WHDI hardware, but cost up to 4-5 times more for a decent range. I think the price difference is due to the market for this device: drone and RC enthousiasts. This is a huge market compared to broadcast.

Compared to putting long cables, this is a huge time saver. It also allows to move the camera easily, without rewiring. It can even be used with battery packs on top of a shoulder cam to be used in crowds I think. We will test this for sure :)

It may be illegal in some countries to use this device, especially with range boosters, so check this before buying :)

There are some SDI options, but not for the same price. Take a look at the paralinx and the terradek website to find those options. I wonder why you would need SDI anyway, if the distance between camera and transmitter are only maximum a meter or 2?

For us this is no problem, since we record audio from the PA system, or a mixer, or microphones and never use internal sound. If you want audio it might not be the best device indeed. There are wireless audio systems, but i doubt any of them will go this far :)

Initial tests indoors were positive except for the heat generated by the transmitter. It seems the fan on the transmitter is not working. I will be returning the unit for a replacement shortly.

We did a long range test today, using a connex, connected to an xha1 with a component to hdmi converter. It was used to send various shots from different parts of a festival to a LED screen on a stage.

We wanted to be completely mobile, so we built a little backpack that included everything to do run and gun shots completely wireless.

We powered the connex from a lipo battery and the converter from an anker battery. All went well :) The connex transmitter can run easily up to 8 hours from a single 5 amps 11.1v lipo battery. The converter didn't even use a fifth of a 26 amp anker battery.

We went up to 400 meters away with line of sight, 100 meters with some tent blocking the LOS. No problems at all, except on long distance if the antenna's were not properly aimed at the reciever. We started to see some strange blocking then. We also had to move the antenna a little higher and away from a LED screen to get the best performance. But overall it was functioning very well.

We will now make a more 'pro' looking backpack, and add some higher gain antenna's. Once we have added some antenna's, we will test longer ranges. To be continued...

Cool, nice weather!
Thanks for sharing :)

I assume it is possible to disable the info row in the video.

There is coming DJI Lightbridge 2 at $1,399. But it's more for drones. HDMI, 1.2 Mile Range, SDI output on receiver, latency 50 milliseconds.

have you ever tried that?
cause i don't think that'll ever work

bandwidth too small, wifi unriable by nature and high latency.
