The Raspberry Pi and its HQ camera make a surprisingly potent webcam, and if you want to cover the basics, and rival the image quality of all but the highest-end dedicated webcams, you can do it for under $100. - Jeff Geerling

• Show-me webcam - This firmware transforms your Raspberry Pi into a high quality webcam. It works reliably, boots quickly, and gets out of your way.

• a Remote Raspberry Pi Desktop/Camera/Server - I made this 3D Printed Camera, it’s not just a camera but a full Linux Desktop based on Raspberry Pi 4 and has 8GB RAM, 12MP camera with a 16mm Telephoto Lens. The images that came out of it are great.
