Hi Guys,
I have 4 of the Nyrius prime/pro/home devices. I am using them with the ATEM TVS. They work impressively well. I have never used the Arrow so I can not comment on it.
Not joining the argument. Just putting in my two cents on what I have learned and done.
I can say however that the Nyrius devices DO use the AMIMON chipsets. I have disassembled my devices and changed the receivers antenna configuration, in the process of doing so, looked up the components.
There is another unit, which is the same exact unit as the NYRIUS Prime made by Optoma (WHD100) which can be found around the same price or a little cheaper. I have tested them and they work together. The blinking lights tend to be rather bright and distracting to camera people and audience or talent so I covered them with electrical tape. I also zip-tied down the mini USB lead on the transmitter units so that they can not come off while on a shoot. The transmitters get rather hot, I do not know how they will faire on a hot day.
I have tested them at all the resolutions available on the TVS and they work great at 720/1080. I have also found that I can run a mix/match 60i consumer and 30p as long as they are at the same resolution. These units seem to do best line of sight, once walls get in the way the range drops extremely fast. There is a delay of about 2 frames, once coupled with the delay in the TVS this adds up to 3-4 frames if you are pumping in audio to the AES3i bnc. I can deal with this lag, it is acceptable and unnoticeable unless you are nitpicking, since I am just streaming to the web over Livestream and ustream.
The Pro device is the same as the Prime, the only difference seems to be the IR unit which is conveniently missing it's transmitter bulb but present on the circuit board. I haven't found any difference in range between the two. The one that is different is the "Home". I have gotten much better range with that unit, the actual output milliwatts seem to be higher.
I purchased some of these little battery units to power the transmitters for a fully wireless solution:

They actually last longer than my Anton Bauer batteries (around 6hrs). I tried the lower voltage 5v USB port but noticed that it had trouble syncing up, so I run it from the higher output port and it works perfectly fine. For a portable solution, it is fantastic. All my cameras run SDI into hyperdeck shuttles and the shuttles have the Nyrius transmitter sticking out, then they transmit back to the base station. My cameras are never farther than 100 ft away line of sight.
That's my two cents,
Cheers
