Use this check to inspect a browser, device, network, permission, media, or input capability directly in the current runtime before relying on it in another workflow.

Webcam probe

Captured webcam probe supplied by the running surface.

Diagnose a webcam from a captured frame probe, reporting verdict, frame rate, and resolution. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Verdict

Overall webcam diagnosis.

Estimated FPS (fps)

Estimated frames per second from frame timestamps.

Frame count

Number of analyzed frames.

Width (px)

Width of the most common frame size.

Height (px)

Height of the most common frame size.

Resolution class

Classification of the most common frame size.

Issues

Stable machine-facing degradation codes.

• Results describe the current browser session and can change with permissions, privacy controls, hardware, drivers, network path, power state, or browser updates. Unsupported or withheld information is not proof that the underlying capability is absent.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Repeat the check in the browser and device that will actually be used, then confirm important behavior with the relevant operating-system or network diagnostics. Avoid granting permissions that are unnecessary for the test.

• Microphone Tester

  Diagnose a microphone from captured level windows, reporting verdict, loudness, and noise floor.

• Audio Output Tester

  Diagnose audio playback from an output probe covering rate, channels, latency, and underruns.

• Display Checker

  Analyze a display probe into refresh rate, resolution class, and pixel density estimates.
