Cameras? I suppose the world still has some weird cameras that need proprietary/weird drivers, but for all intents and purposes: USB cameras are UVC and work with a generic driver, and IP cameras are OnVIF and work with ffmpeg. I can't imagine the latter having any OS dependencies as far as Linux/BSD/Mac/Windows is concerned. Quality is fine - I have a bunch recording 24/7 with high quality audio and video.
