DEVICE TESTS
Webcam test
Check your camera picture, resolution and frame rate. Take a local snapshot or record a short camera-only clip.
Start to allow camera access. Video stays in this tab; no microphone is requested. Snapshots and recordings happen only when you choose.
Resolution is a preference, not a guarantee. Read the actual applied settings below. Changing resolution restarts the test and deletes temporary captures.
Start once to reveal available inputs. No device is accessed until you start.
Ready when you are.
Wrong camera or no picture?
- Check the camera shutter or cover. After starting, compare the picture and the Testing label with the camera you intended to use.
- Choose another input above, or reconnect it and use Refresh devices. Changing inputs deletes temporary captures and restarts the test.
- If the input is still missing, stop this test and check the input in your system settings. If it works here but not in a call, choose the same input and check permissions in the call app separately.
A signal or picture only shows what this browser receives now. It does not prove that every hardware feature or calling app works.

Browser-reported settings are not an independent hardware quality score. The microphone meter is relative signal strength, not calibrated loudness.
