Microsoft Teams camera not detected?

Verify a real camera stream

Start the Webcam Test and select the intended camera. A device name alone is not enough: confirm that frames arrive, the preview moves, and resolution and frame rate appear.

• NotFoundError or no camera: inspect the physical connection and whether the operating system lists a camera.
• Permission blocked: correct browser and operating-system privacy settings.
• Camera busy or unreadable: close other apps and retry before reinstalling anything.
• Live preview: move on to Teams-specific selection.

Select the same device in Teams

1. Open Teams Settings, then Devices or Audio and video.
2. Choose the exact camera name shown by MeterSee.
3. Open the Teams preview and confirm framing before entering the meeting.
4. If the preview is black, close the settings panel, quit Teams completely, and reopen it once.

Release the camera from other software

1. Close Zoom, Meet tabs, OBS, Camera, streaming tools, virtual-camera utilities, and remote-desktop sessions.
2. Open Teams again and test before reconnecting optional virtual-camera software.
3. For a USB camera, connect directly rather than through an unpowered hub and compare another port.

Check privacy and physical controls

1. Open the physical shutter and use the laptop camera privacy key if present.
2. Allow camera access for desktop apps and Microsoft Teams in Windows or macOS privacy settings.
3. For Teams in a browser, allow camera access in the address-bar site controls, reload, and select the device again.

When to update or repair

Update Teams and the operating system after the lower-risk checks. Consider driver or hardware service only if the camera also fails in MeterSee and the built-in Camera/Photo Booth app. If only Teams fails, preserve the working browser evidence for your administrator.
