Frequently asked questions
Why doesn't my camera turn on?
Check that no other app (Zoom, Teams, OBS) is using the camera simultaneously. Verify browser camera permissions are enabled in your browser settings.
How do I switch between multiple cameras?
Use the camera selector dropdown to switch between built-in webcam, USB camera, and virtual cameras.
Why is my camera feed blurry?
Autofocus may need a moment to adjust. Ensure adequate lighting — cameras perform poorly in low light. Clean the lens if needed.
