Use the browser test to separate camera hardware/access from Zoom-specific selection and permission problems.
If the live test passes, the investigation can usually move away from total hardware failure and toward the affected app, permissions, routing or configuration.
Try the simple causes first
- 1
Run DeviceOK webcam test.
- 2
In Zoom, select a different camera and then the intended camera.
- 3
Verify Zoom can access the camera in OS privacy settings.
Work through the problem in order
- 1
Run DeviceOK webcam test.
- 2
In Zoom, select a different camera and then the intended camera.
- 3
Verify Zoom can access the camera in OS privacy settings.
- 4
Close other apps using the camera.
- 5
Follow Zoom's official camera troubleshooting if it still fails.
Use the passing DeviceOK test to narrow the problem to the specific app or settings layer.
If DeviceOK also fails, step back to permissions, connection, OS configuration, and device-level troubleshooting.
