Test your camera in Teams settings before you join a call
Open Microsoft Teams and select your profile picture in the top right corner. Click Settings, then choose Devices from the left menu. Under Camera, you will see a preview window showing what your camera sees in real time. If you see your face or the room behind you, your camera is working. If the preview is black or blank, your camera is either disconnected, blocked by another process, or not recognized by your computer.
This is the fastest way to check before joining a meeting. You do not need to start a call or involve other people. The preview updates as you move, so you can adjust your position, lighting, or camera angle right there in settings and see the result when ready.
Key Takeaways
- Go to Settings > Devices > Camera in Teams to see a live preview of what your camera is sending without joining a call.
- A black or blank preview means your camera is disconnected, in use by another app, or not installed on your computer.
- You can test camera focus, lighting, and framing in the preview before you join a meeting with other people.
- If your camera works in the preview but not during a call, restart Teams or check whether another process has locked the camera.
What to do if the preview shows nothing
First, check that you selected the correct camera. If your computer has more than one camera (built-in and external, for example), Teams defaults to one of them. In the Camera section of Devices settings, click the dropdown menu next to your camera name. You will see a list of all cameras your computer recognizes. Select each one and watch the preview to find which one is working.
If switching cameras does not help, or if you only have one camera and it shows nothing, the camera may be in use by another process. Close video conferencing apps, streaming software, or any other program that might be using the camera. Then return to Teams settings and check the preview again. If it still does not work, restart your computer and try once more.
Check camera permissions on Windows or Mac
Your operating system controls which applications can use the camera. On Windows 10 or 11, go to Settings > Privacy & Security > Camera. Make sure the toggle for "Camera access" is turned on. Then scroll down to "Allow apps to access your camera" and confirm that Microsoft Teams is listed and switched on.
On Mac, go to System Preferences > Security & Privacy > Camera. You will see a list of applications that have requested camera access. Find Microsoft Teams in the list. If it is not there, Teams has never been granted permission. If it is there but unchecked, click the checkbox to allow it. Close System Preferences and return to Teams.
Test your camera during a practice call
Teams includes an Echo Bot that lets you make a test call without involving another person. In Teams, go to Settings > Devices and scroll down to the bottom of the page. You will see a section called Make a test call. Click the button to start a call with the Echo Bot. The bot will ask you to record a short message and play it back to you. During this call, you can see yourself on screen and hear your own audio, which confirms both are working.
This test is more realistic than the preview because it shows how you will appear to others during an actual meeting. You can check your framing, whether your face is well-lit, and whether the camera focuses properly on you rather than the background. After the test call ends, Teams will show you a summary of what worked and what did not.
Adjust camera settings for better video quality
In the Camera section of Devices settings, you may see additional options depending on your camera model. Some cameras let you adjust brightness, contrast, or focus. If these controls are available, experiment with them while watching the preview. Increase brightness if the preview looks dark. Adjust focus if your face appears blurry while the background is sharp, or vice versa.
Keep in mind that camera quality also depends on lighting in your room. Natural light from a window in front of you produces better results than overhead lights or backlighting. If your preview looks grainy or dark even after adjusting camera settings, try moving to a brighter location or adding a desk lamp in front of you.
Restart Teams if your camera worked before but stopped working
Sometimes Teams loses connection to your camera during use. Close Teams completely — not just minimize it, but fully quit the process. On Windows, right-click the Teams icon in the taskbar and select Quit. On Mac, click Teams in the menu bar and select Quit Microsoft Teams. Wait a few seconds, then reopen Teams and return to Settings > Devices > Camera to check the preview again.
If restarting Teams does not restore the camera, restart your computer. This clears any locks on the camera that may have been left by another process or a previous Teams session. After your computer restarts, open Teams and test the camera preview once more.
Frequently Asked Questions
Why is my camera preview black even though the camera works in other apps?
Teams may not have permission to use your camera, or it may be using the wrong camera if you have more than one. Check your operating system camera permissions (Windows: Settings > Privacy & Security > Camera; Mac: System Preferences > Security & Privacy > Camera) and make sure Teams is allowed. Also check the Camera dropdown in Teams settings to confirm you selected the right camera.
Can I test my camera without starting a call?
Yes. Go to Settings > Devices > Camera in Teams and watch the live preview. You can adjust your position, lighting, and camera angle and see the changes when ready. You do not need to join a meeting or use the Echo Bot test call unless you want to see how you appear to others during an actual call.
What if my camera works in the preview but goes black when I join a meeting?
Another process may have taken control of your camera after you opened Teams. Close any other apps that use video, then rejoin the meeting. If the problem continues, restart Teams completely and try again. If it still does not work, restart your computer.
How do I know if my camera is focused correctly?
Look at the preview in Teams settings. Your face should be clear and sharp. If your face is blurry but the background is sharp, or vice versa, your camera focus is set wrong. Some cameras let you adjust focus in the Camera settings. If your camera does not have focus controls, try moving closer to or farther from the camera until your face appears sharp.
Does the Echo Bot test call show me exactly how I look to others?
Yes, the Echo Bot call shows you the same video that other people see during a real meeting. You can check your framing, lighting, and whether your camera is focused on your face. This is more realistic than the preview alone because it shows how Teams processes and sends your video.
