And that without calling in twice. Laptop cameras as normally very crap. They say “1080p”, but most of the time they are 720p or less and have maybe 2 megapixels or less. Phones have way more and can be connected to the laptop via USB. There must be a way to use their camera over USB, right?

I know of USB over LAN, so surely this is possible.

Thanks to everybody. In the end I went with Scrcpy.
