How can I check my camera and microphone before a video call?

Quick answer

Run the combined pre-call test and allow access to your camera and microphone. Look for a live video preview and speak to trigger the input meter. Then separately confirm your speakers using the speaker test or guided Quick Device Check.

How to run this test

  1. Close competing video apps if they are using the same camera.
  2. Start the pre-call check and approve camera and microphone access.
  3. Confirm that your face or subject appears in the video preview.
  4. Speak and check that the microphone activity meter responds.
  5. Use Quick Device Check to confirm speaker playback before joining a call.

Understanding your result

✓ What a good result looks like

You can view a live video stream and the microphone input meter registers your speech.

! If something does not work

Working browser streams do not guarantee the meeting app uses the same selected devices or that your network connection is stable.

Troubleshooting common problems

Camera works, microphone does not

Check OS and browser microphone permissions, input selection and mute switches.

Microphone works, camera does not

Check the privacy shutter, browser site permissions and whether another application uses the camera.

Everything works here but not in a meeting

Select the correct camera, microphone and speaker inside the meeting app, then run its own test call.

What this browser test cannot prove: This checks local browser media access, not internet speed, network stability, meeting-room permissions or end-to-end call performance.

Frequently asked questions

Can this test guarantee Zoom or Teams will work?

No. Each meeting app has its own permissions, device selection and network requirements.

Does this test my internet connection?

No. This check verifies local video and audio input; it does not measure your connection speed or packet loss.

Can I test speakers too?

Use the guided Quick Device Check or the standalone speaker test to play a tone and confirm what you hear.

Is my video call recorded?

No. This page previews camera and microphone input locally and does not make or store a meeting recording.
