Wyjaśnienie techniczne
The test uses getUserMedia() to request a video track from the browser. The preview is drawn by a native HTML video element, so the image is shown locally. Browser-reported track settings expose width, height, and frame rate when the hardware and driver provide them.
A webcam can deliver a valid stream while still having a focus, colour, or low-light problem. This tool checks that the camera is detected and producing frames; it does not calibrate image quality or certify the sensor.
Rozwiązywanie problemów
No permission prompt
Check the site permissions in your browser address bar. Blocked camera access must be reset there before the page can ask again. On macOS or Windows, also check system privacy settings.
Black preview
Close other apps that may hold the camera (video calls, security software), reconnect external cameras, and reload the page. Some virtual cameras only start after their companion app is running.
Wrong camera
Use the camera selector. Device labels are only exposed after permission has been granted, which is a browser privacy rule.
Frozen or low frame rate
USB bandwidth, lighting, and driver settings can limit frame rate. Try a lower resolution in your camera app or a different USB port.
