The UVC - USB Video Class device specification is firmly entrenched in the low-level software code of all major operating systems: Not just OSX, but Windows, Linix and Android OS as well. As such we expect that vast majority of more recent UVC compatible web cameras to work on the 10.15 version of Catalina MacOS without a hitch.
If there's any quirks about MacOS Catalina webcam compatibility, we'll note it on this website. As more app developers and end users deploy their webcams under the Beta and full release of Catalina we'll be sure to hear of particular cameras that exhibit any problems or issues.
There may be much older web cameras with outdated UVC device implementations that aren't up to snuff and may be problematic for use on MacOS Catalina, However most modern webcams should work on a Macs running Catalina just fine.
I have an external webcam that I would like to use instead of the webcam built in to the iMac. For audio, I can go to System Preferences -> Sound -> Input and select a device for sound input. With video though, there is no such option I can find. I can manually select the webcam when I use FaceTime or Skype, but I have to manually go into the preferences for each application every single time I open it. Neither application nor the operating system has a way of setting a default webcam that I can find. Any help would be greatly appreciated, thank you!
