Use your phone camera as a webcam
The first is the NDI HX Camera app from NewTek
NDI Virtual Input utility that tricks your video software into accepting the NDI input as a webcam is only available in NDI Tools for Windows
If you’re wanting to use an Android phone as a webcam, one of the most polished options we’ve found is DroidCam. Again, this only works with Windows, via the desktop client, but setup is simple—launch the Android app and it gives you an IP number that you can type into the Windows client, and you’re up and running.
