Issue: Microsoft Teams fails to activate camera during meetings. 

Solution: Microsoft Teams can recognize the camera without additional steps. However, if you cannot start a video conference, you may be experiencing settings problems related to the camera.

To configure the camera settings on Microsoft Teams, use these steps:

1. Open Microsoft Teams.

2. Click the main menu (three-dotted) button from the top-right corner.

3. Select the Settings option.

4. Click on Devices.

5. Under the "Camera" section, use the drop-down menu and select the correct camera.

6. Confirm with the preview to make sure the camera is working.

Once you complete the steps, make a test call or call someone to determine whether the camera is working.
