A black Google Meet camera preview can come from a covered lens, the wrong video source, denied access, or another application using the camera. Check these separately before treating the webcam as broken. A black picture and a permission error may require different next steps.
Inspect the lens and video source
Confirm that an external camera is connected and powered, and that it faces the intended subject. Open any physical camera cover or privacy switch when you are ready to transmit video. In Meet’s camera dropdown or Settings and Video, choose the actual webcam rather than an inactive virtual source or another device. Look for a live preview after changing the selection.
Compare the built-in camera application
Open Camera or Photo Booth to see whether the same device produces an image outside Meet. If it does, close that application and return to Meet. Inspect camera permission for the Meet site and the browser’s operating-system access. Google notes that a Camera failed error often means the browser cannot access the device. Reload Meet after closing other camera users.
Separate a local fault from call quality
If the camera application is also black, check device-specific privacy controls and the physical shutter before escalating a hardware problem. If the local preview works but remote participants see frozen or poor video, investigate the connection and call quality separately. Use a supported, updated browser through your normal update process. Do not reset the computer or remove browser data as an opening step. Record the selected camera, preview result, and any error message. Join with video off if necessary, then verify the repaired camera with a short live image check before relying on it for an important demonstration.
