You can connect the iPhone with a wired ethernet connection.

That will most likely help a lot.

There are hits on google to tell you how to do that with USB kit and adaptor, or you can just get a Rebotnix adaptor

The next thing to look at is how much other WiFi noise/traffic is in your area. Perhaps use tool like InSSIDer to see what else is active your area.

Beyond that, I'm not sure what bad the signal is that you are seeing, but NDI® pushes WiFi to it's limits.

As for NDI|HX, it is mainly designed for hardware solutions, while the standard NDI is more for software solutions (but can be implemented in hardware like BirdDog has done). I'm not sure if you will see NDI|HX support on iOS or Android.

I don't have any recommendations on specific models.

I just tried NewTek NDI Camera on my home network. I'm using my AT&T WiFi access point, which is upstairs while I was doing the test from downstairs. In the standard quality mode, I'm getting very smooth video, maybe a small blip once in a while, but more than useable. In high quality mode, I'm getting poor frame rate, it wouldn't be usable.

I've done a bit of tweaking with my access point. I do have it set to 40Mhz bandwidth and WPA2/AES. But that is about it. Something else that might help is forcing the access point to only allow the highest speed connections (N or AC only).

Lastly, you don't have the receiving device also on WiFi do you? In my test, the only WiFi part of the connection was from the phone to the router, it was then PowerLine to Ethernet to my laptop after that. If I had both my laptop and phone trying to both send and receive the NDI signal via WiFi, I doubt it would work well.

Hi Kane and Livepad .
Thanks for the tips.
I have my vmix computer hardwired to the router and have given the phone high priority.
I have tried the phone in low quality mode and vmix in low bandwidth mode.
THe low bandwidth mode on the ndicam on the phone is not worth using .
Keeping the phone on highbandwidth mode and then the putting vmix mdi into low bandwidth mode has given me my best results.
Don't know wether it will be good enough to use though in any professional way probably too different from the rest of the cameras.
Is there any roadmap for updating the ndicam app to improve efficiency?

That's a bit disappointing. It seems like mobile devices on wifi are just the right use case for NDI|HX. Maybe I don't quite understand its intent or limitations.

Interestingly enough, there's an NDI video app on iOS called JustWifiCam that purports to have just added NDI 3.0 compatibility in its latest update. I've tested the app with vMix, but it's also supposed to work with other video systems that support NDI video (JustBroadcaster, Tricaster, OBS, etc.).

So, am I missing something about NDI|HX, or is somebody else? Maybe I'm assuming that NDI 3.0 automatically makes NDI|HX available for that device, so long as your control system supports it, too. I do hope that's right.
