FAQ

Can I test my mic and camera together?

Yes. Use quick check here or open the dedicated pages.

Do I need to install anything?

No. Press Start only for the device you want to test, then allow that one browser prompt.

Why does the browser ask for permission?

Browsers require permission before any page can use your mic or camera. MicAndCam asks only after your click and stops tracks when you leave.

Is my audio or video uploaded?

No. The meter, preview, snapshots, and recordings are created locally and are not uploaded.
