How to run this check
Start capture and remain here for several seconds; improve lighting and compare the delivered FPS.
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
Delivered FPS differs from configured frame rate and does not establish the camera maximum. Some browsers lack frame callbacks.
If something seems wrong
Improve lighting, close other camera apps and try a different port before retesting.

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.
