I remember the last time I tried to find a cheap webcam that works on linux, I gave up pretty quickly and just used my laptop for video calls. Saw this guide to build one with a zero 2, had a spare board in my parts drawer so thought why not. I’m surprised by the quality of it. I’ve been using it for work meetings.
What resolution and fps are you getting? I did a couple of tests some time ago and I found it to be quite laggy at 720.
Looking in terminal, it doesn’t look like it can put out more than 30fps. It defaults to 1080, I have the camera 3 module. That said, there is some lag at both 720 and 1080, although it doesn’t seem worse at 1080 than 720. Still, plenty good enough for it’s purpose, which is just to put my face in the teams call.
