They are all screens. Rarely I record a design on the whiteboard and I end up in the frame, but I'm fine with it. BTW this also works much better than any spec.

Self consciousness is an interesting problem. I prefer seeing faces on the screen during the stand-up (such as it is in the days of COVID), but I was told many hesitate to be on camera.

Did you ever find a way out of this? Join.me has very small video size, I imagine this is one way to lessen the stress. Alas it doesn't work for me - I need to see the facial expressions because I need to know when I lost the audience, and because I find it hard to pay attention to a disembodied (and heavily compressed) voice.
