Fix Teams Camera Is Not Detected on Windows 11

When you start a Teams meeting and the video stays off, the camera icon may show a red slash or the message “Camera is not detected.” This happens even though the camera works in other apps. The cause is often a Windows privacy setting, a driver conflict, or Teams not having permission to access the camera. This article walks through the checks and fixes that restore camera detection in Teams on Windows 11.

You will learn how to enable camera access for Teams, update or reinstall the camera driver, and reset the Teams app if needed. Each step is ordered from the most common fix to the least common. After following these steps, you can join video meetings with confidence.

Why Teams Camera Detection Fails on Windows 11

Teams uses the Windows Media Foundation framework to access cameras. If Windows blocks the camera at the system level, Teams cannot see it. The most common blocker is the privacy setting that prevents desktop apps from using the camera. Windows 11 applies this setting per app, and Teams is treated as a desktop app.

Another frequent cause is a camera driver that is outdated or corrupted. After a Windows update, the driver may no longer match the hardware, so the camera appears in Device Manager with a yellow warning icon. Teams then reports “Camera is not detected” even though the camera is physically connected.

Finally, Teams has its own device settings that can point to the wrong camera or disable video. If you have multiple cameras, such as a built-in webcam and an external USB camera, Teams may select the wrong one. The steps below address each of these causes in order.

Steps to Enable Camera Access and Fix the Driver in Windows 11

Follow these steps in the order shown. Test Teams after each major step to see if the camera is detected.

1. Enable camera access for Teams in Windows Settings
   Press the Windows key and type “Camera privacy settings” then press Enter. In the Settings window, turn on “Camera access.” Then turn on “Let apps access your camera.” Scroll down and make sure “Let desktop apps access your camera” is also on. If any of these are off, Teams cannot detect the camera.
2. Check that Teams has permission in the same settings page
   In the Camera privacy settings, look for the list of apps under “Let apps access your camera.” Find “Microsoft Teams” and confirm its toggle is on. If it is off, turn it on. If you do not see Teams in the list, click the “Add a desktop app” button and select Teams from the file dialog.
3. Update the camera driver in Device Manager
   Right-click the Start button and select “Device Manager.” Expand the “Cameras” or “Imaging devices” section. Right-click your camera device and choose “Update driver.” Select “Search automatically for drivers.” If Windows finds no new driver, go to the next step.
4. Uninstall and reinstall the camera driver
   In Device Manager, right-click the camera device and select “Uninstall device.” Check the box “Delete the driver software for this device” if it appears, then click Uninstall. Restart your PC. Windows will install the default driver automatically. Then test Teams.
5. Select the correct camera in Teams settings
   Open Teams and click your profile picture at the top right. Select “Settings,” then “Devices.” Under “Camera,” click the dropdown and choose your camera. If you see a preview of yourself, the camera works. If not, try the other camera in the list.
6. Reset the Teams app cache
   Close Teams completely. Press Ctrl+Shift+Esc to open Task Manager and end any Teams processes. Press Windows key + R, type %appdata%\Microsoft\Teams and press Enter. Delete the “Cache,” “Code Cache,” and “GPUCache” folders. Restart Teams and test the camera.

If Teams Still Cannot Detect the Camera After These Steps

Teams Shows a Black Screen or “Camera Not Detected” After a Recent Windows Update

Windows updates can change camera drivers. Check for a newer driver from your PC manufacturer. Go to the manufacturer’s support website and search for the latest camera driver for your model. Download and install it. If no driver is available, roll back the driver in Device Manager. Right-click the camera, select “Properties,” then “Driver” and click “Roll Back Driver” if the option is active.

The Camera Works in Other Apps but Not in Teams

This points to a Teams-specific setting. In Teams, go to Settings > Devices and confirm the correct camera is selected. Also check if another app like Zoom or Skype is using the camera. Close those apps. If the issue persists, sign out of Teams and sign back in. This refreshes the device permissions.

Teams Does Not Show Any Camera in the Device Dropdown

The camera driver may not be loaded. Open Device Manager and look for the camera under “Cameras.” If you see a yellow triangle, the driver is not working. Right-click and select “Enable device.” If that does not help, uninstall the device and restart your PC as described in step 4.

Teams Camera Fixes on Windows 11: Desktop vs Web vs Mobile

Item	Teams Desktop App	Teams on the Web
Camera permission location	Windows Settings > Privacy & security > Camera	Browser settings (e.g., Edge or Chrome site permissions)
Driver update method	Device Manager or manufacturer website	Same as desktop, because the OS still controls the driver
Device selection	Teams > Settings > Devices	Teams web > Settings > Devices (same interface)
Common fix after update	Reset Teams cache or reinstall app	Clear browser cache or reset browser permissions
Camera preview test	Available in Settings > Devices	Available in the meeting pre-join screen

The desktop app and the web version share the same Teams interface for device selection. The key difference is where the operating system or browser grants camera permission. For the web version, check the lock icon in the address bar and confirm that camera access is allowed for the Teams site.

Conclusion

You now know how to fix a camera that Teams does not detect on Windows 11. Start with the Windows privacy settings, then update or reinstall the camera driver, and finally adjust the device selection inside Teams. These steps cover the most common causes and will resolve the issue in most cases.

After fixing the camera, test it by starting a test call in Teams. Go to Settings > Devices and click “Make a test call” to verify both video and audio. If you use a USB camera, try a different USB port to rule out a loose connection.

For advanced troubleshooting, use the Teams device diagnostics tool. Press Ctrl+Alt+Shift+1 in Teams to open the diagnostic panel and view camera status. This tool shows detailed error codes that can help you identify a hardware or driver conflict.
