When it come to quality its better to use a decent camera and a capture card. Also you need to get the usb / webcam signal to your system.
For all on the search i would also talk about NDI... either NDI as capture device (birddog studio i.e.) or use a camera with NDI output.
There is a NDI App to turn every smartphone into an NDI source.... but only the compresed ndi/HX version.
it may worth a shot...
