Private camera preview
Permission is requested only when you start.
Understanding your camera preview
A visible preview confirms that the browser received permission, obtained a video stream, and displayed frames locally. Reported resolution comes from the active browser track and may differ from the camera's maximum specification.
A black image may come from a privacy cover, another app using the camera, the wrong selected webcam, a loose external-camera connection, or an operating-system privacy restriction.
Troubleshooting
Black preview
Remove any physical privacy cover and make sure another application is not using the camera.
Permission blocked
Allow camera access from your browser's site controls and reload if needed.
Wrong camera
Choose another camera from the selector after permission is granted.
Webcam Test FAQ
Does this test upload video or captures?
No. The live preview and captured image remain in this browser tab and are not added to reports.
Why is the image mirrored?
A mirrored self-view feels natural for positioning and does not mean other apps will record mirrored video.
