I can't see a USB webcam under camera options in Zoom Meeting.
Note: If you are on Mac OS 10.14 Mojave and are still having difficulty accessing your webcam, check your operating system permissions to confirm that Zoom has access to the camera.
If you are using Windows and are still having difficulty accessing your webcam, Windows 10 has a privacy feature that may block Zoom from using the camera. Learn more about this feature and how to allow Zoom access to your webcam here.
