How to run this check
Start the camera, select an exposed input or front/rear preference, and read negotiated dimensions.
Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
Negotiated stream dimensions are not the sensor maximum. Lighting and focus still need visual review.
If something seems wrong
Select another camera or compare camera-app settings, then restart capture.

Does a pass guarantee my hardware is healthy?
No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
