Why does the camera label appear after permission?

Browsers hide detailed device names until you grant access, which helps protect privacy before a site is approved.

Can this page judge camera quality perfectly?

It can show practical stats like resolution and frame rate, but it cannot produce a perfect quality score from the browser alone.
