There is nothing worse than joining an important call and discovering your camera or microphone is not working — especially when the other person can see you frantically unmuting yourself. Taking two minutes to test your audio and video before a call can save real embarrassment. Here is how to do it quickly in Windows 11.
Test Using the Windows Camera App
Windows 11 includes a built-in Camera app that gives you an instant preview of your webcam:
- Press Windows + S and type Camera
- Open the Camera app
- You should see a live feed from your webcam immediately
If the image appears, your webcam hardware is working correctly. If you see an error message, check out our guide on fixing a webcam not working in Windows 11.
Test Your Microphone in Windows Sound Settings
Windows 11 has a built-in microphone test tool:
- Right-click the speaker icon in the system tray and select Sound settings
- Scroll down to Input
- Click on your microphone
- Speak into the microphone — you should see the input level bar move
If the bar does not respond when you speak, your microphone is either muted, set to the wrong input device, or has a driver issue. See our microphone troubleshooting guide for fixes.
Test in Microsoft Teams Before a Meeting
Teams has a built-in device test that checks both camera and microphone before you join a call:
- Open Microsoft Teams
- Click your profile picture in the top right
- Go to Settings > Devices
- Click Make a test call
Teams will call an automated bot that plays back your voice so you can hear exactly how you sound to others. It also tests your speakers.
Alternatively, when joining a meeting, Teams shows a preview screen before you enter — use this to check your camera and confirm audio settings.
Test in Zoom Before a Meeting
Zoom offers a similar pre-call test:
- Open Zoom and go to Settings (gear icon)
- Click Video — you should see a live webcam preview
- Click Audio to test your microphone and speakers
- Click Test Mic — speak and watch the input level; Zoom will play back what it recorded
Zoom also offers a browser-based test call at zoom.us/test if you want to check everything before installing the app.
Use an Online Webcam Tester
If you want a quick browser-based check without opening any apps, several free websites can test your camera and microphone:
- webcamtests.com — instant webcam preview in your browser, no install required
- onlinemictest.com — tests your microphone input and displays the level in real time
- toolster.net/webcam — shows resolution, frame rate, and live video preview
Your browser will ask for camera and microphone permission — click Allow to proceed.
Check Your Lighting and Background Too
While you are testing, take a moment to check the less obvious things:
- Lighting: Ensure light comes from in front of you, not behind. A window behind you creates a silhouette effect.
- Background: Check for anything distracting or unprofessional in the frame
- Camera angle: Position the camera at eye level rather than looking up or down
- Headphone echo: If you are using speakers rather than headphones, the other person may hear an echo of their own voice
Quick Pre-Call Checklist
- Camera shows a clear picture in the Camera app
- Microphone input level moves when you speak
- Correct camera and mic selected in the app you are using
- Not muted at hardware, OS, or app level
- Lighting from the front, background is tidy
