Fix webcam not working in Microsoft Teams

If your webcam does not work in Microsoft Teams, check that the camera is uncovered, select the intended camera in Teams and confirm that camera access is allowed. Then test the webcam in another camera app to narrow down the problem. For Teams in a browser, check both the browser’s camera permission and the computer’s permission for that browser.

No device details, error message or diagnostic results were supplied, so a specific cause cannot be confirmed. Setting names and locations can vary with your Teams version and operating system.

Check the camera controls and selected input

• 1. Open any physical privacy shutter and check for a camera-disable switch or keyboard control. A closed shutter can block the picture even when the camera is detected.
• 2. For a USB webcam, check the connection. If it is connected through a hub or dock, try connecting it directly to the computer to test that connection path.
• 3. Open Teams settings and find the camera selector, usually under Devices. You can also check camera selection on the screen before joining a meeting.
• 4. Select the physical webcam you intend to use. If several cameras or virtual cameras appear, check which one is active.
• 5. Turn video on and check the preview.

A camera appearing in the selector indicates that Teams can list it; it does not establish that access is permitted or that it can supply video. A working preview shows that Teams can receive video at that moment. Join the affected meeting and confirm that video still works there before considering the issue resolved.

Test whether the problem is limited to Teams

Close Teams and other apps or browser tabs that might be using the camera. Open a separate camera app, such as Camera on Windows or Photo Booth on macOS, and select the same webcam where possible. Close that app before reopening Teams.

• If the webcam works in the other app: the camera can capture video through that app at the time of the test. Focus next on Teams input selection and permissions. This result does not verify Teams access or meeting behavior.
• If the webcam also fails in the other app: investigate physical controls, the connection and permissions for that app. Failure in two apps does not by itself prove that the camera is faulty.
• If the webcam is missing from both apps: check whether the operating system detects it. For an external webcam, reconnect it and try another available USB port.

Check camera permissions for your setup

On Windows 11, open Settings, then Privacy & security, then Camera. On Windows 10, open Settings, then Privacy, then Camera. Check camera access and the applicable app-access controls. Desktop applications can use a separate desktop-app access setting rather than an individual Teams toggle. If you use Teams in a browser, check access for that browser as well.

On macOS, open System Settings, then Privacy & Security, then Camera. Allow access for Microsoft Teams if you use the desktop app, or for the browser if you use Teams on the web. Older macOS releases use System Preferences and different navigation. Quit and reopen the affected app after changing permission.

For Teams on the web, open the browser’s permissions for the current Teams page and check that camera access is allowed. Confirm the intended camera in any available browser and Teams camera selectors, then reload the page and test again. Browser permission and operating-system permission are separate checks; allowing one does not establish that the other is allowed.

If a permission control is locked or managed by your organization, ask your administrator to review it. Camera permission concerns video capture; microphone permission concerns audio capture. Changing microphone access will not resolve a blocked camera.

If the webcam keeps turning off in Teams

Identify what changes when the video stops: does Teams switch the camera off, does the picture freeze or turn black, or does the camera disappear from the device selector? These observations help distinguish a meeting or application issue from loss of the camera connection.

• If the camera disappears from the selector: check whether it also disappears from other camera apps. For a USB camera, test a direct connection and another port. A different result makes the connection path worth investigating, but does not identify a specific failed component.
• If the camera remains listed but video stops: close other camera-using applications, quit and reopen Teams, and retest. Competing camera use is a possible explanation; this check does not establish it as the cause.
• If the problem happens only in one meeting: compare with another meeting and note any message about video availability or meeting restrictions. Ask the organizer or administrator to check restrictions if indicated.
• If your local preview continues while others report frozen video: the preview supports continued local capture at that moment. It does not verify that video is reaching other participants.

Retest and know when to escalate

After each change, repeat the action that originally failed. For intermittent failures, test through the circumstances that usually trigger the interruption; a briefly working preview is not enough to confirm a lasting fix. If reopening Teams does not help, save your work, restart the computer and test again.

If the issue remains, record the camera model, operating system, Teams app or browser version, exact error message, whether the camera is listed, and whether it works in another app. Give those details to your IT administrator or support provider. Driver, firmware and reset procedures require guidance for the specific device and software version; no verified instructions for those actions were supplied here.
