How to use this test

What to do

Start the camera and allow browser access. Move in front of the preview to check that it updates.

What to look for

Check framing and motion visually. Saving a result keeps a summary of the stream settings.

Video track settings describe the negotiated stream. Reported frame rate is not a guarantee that every frame was delivered. Brightness and color readings summarize the preview rather than certify exposure or color accuracy.
