If you encounter errors such as “camera already in use,” “camera unavailable,” or see a blank video feed during your assessment, it usually means another application is accessing your camera. Video conferencing tools and background software can lock the camera, preventing your browser from using it for the assessment. This article explains why these conflicts occur and how to resolve them effectively before or during your test.

Additional Tips

  • Close all camera-using applications before launching your assessment.
  • Check Task Manager (Windows) or Activity Monitor (Mac) to confirm no background processes are using the camera.
  • Restart your system 5–10 minutes before the test for a clean setup.
  • Keep system monitoring tools accessible during the test for quick troubleshooting.
  • If using a work-managed device, confirm with IT whether monitoring software may interfere.
  • Disconnect and reconnect external webcams if used.
  • Consider keeping a backup device available in case camera conflicts cannot be resolved quickly.
