Hello fellow hacker that was the first thought we even thought to provide a camera source like snapcam and others do but we wanted to keep it simple and take a zero installation approach this is output we got.

An interesting tidbit, on javascript side even if we are paying a video, we expect phones to not turn off display but some phones still turn off the display. This was one scenerio when we thought app would be appropriate

Realistically do most people even have separate webcams at home?

I know I don't, but there's at least 5 smartphones somewhere in the house. Harnessing those cameras via wifi is pretty useful.

I don't have a separate webcam, but I use my Pixel 2 as an OBS webcam with DroidCamX with much better quality that a fancy $200 Logitech webcam. There is a similar app for iOS. Even better, you can use multiple phones for different angles or to point to a notepad.
