Permission is not a test result.
Confirm the actual image is clear and not frozen. The displayed FPS is the track setting reported by the browser, not a guaranteed measured frame rate. Video stops when this page is hidden.
How to use this test
- Allow camera access and select your device.
- Check clarity, movement, lighting, and framing.
- Stop the camera and save your observation.
Why does the camera not open?
Check permission, the lens cover, and whether another app is using the camera. HTTPS or localhost is needed. TestZio never uploads camera video.
Where is my test data stored?
The test runs on your device. Results are only saved to this browser when you choose Save. Clear them from the report page at any time. Audio and video are never uploaded.
