Answers.Text: Well, that sample video looks great on my 6ft OLED TV :) Trust me, the students mostly have very good Internet speed and the right viewing screens. My post is about Webcam features for video recording.
  
  What I am actually asking is with which cam can I shoot similar quality videos at 1080 60fps?
  
  Which of those allows locking the focus on the whiteboard so that the text does not become blurry when the teacher moves and the camera auto focuses?

Answers.Text: Now, you are asking another question about autofocus, or manual/fixed focus. Then simply look for that spec in the features of the cameras, or look for a small aperture like f/8.

  Having a 4k or 8k camera will not do anything with bad light, and if the students still are using the same screen.
  
  Besides taking a look at how your setup looks, there is something really simple you can and should do.
  
  **Do not shoot at 60FPS**.
  
  If your students have low bandwidth, don't send them unnecessary high framerate for a professor talking. If you use 30FPS you are sending half the information, so you can actually double the quality of the compression!
  
  If your camera shoots at 24FPS even better!
