A camera that won’t turn on right before a meeting is one of the most stressful Teams problems, mostly because the cause could be anywhere between three different layers: your hardware, your operating system’s permissions, or Teams itself. We’ve broken the fix down by layer so you can find the right one fast instead of guessing.
Quick Answer
Most Teams camera failures come down to camera permissions being blocked at the operating system level, another app (Zoom, Skype, browser tabs) already holding the camera, or an outdated camera driver. Closing other camera apps, re-granting Teams camera permission in your OS privacy settings, and restarting Teams resolves this for the large majority of users.
Why Your Camera Isn’t Working in Teams
1. Operating System Privacy Permissions
Both Windows and macOS require explicit per-app permission to access the camera. If Teams was installed or updated after you last granted this permission, or if a system update reset privacy settings, Teams can silently lose camera access without any obvious error message.
2. Another Application Is Using the Camera
Most webcams can only be accessed by one application at a time. If you have Zoom, Skype, a browser tab with a video call open, or even a camera/streaming app running in the background, Teams won’t be able to grab the feed even though it looks like it “should” work.
3. Outdated or Corrupted Camera Drivers
Windows in particular relies on drivers to bridge the physical camera and any app trying to use it. A driver that’s out of date, or was corrupted by a recent Windows update, is one of the more common hidden causes of a “black screen” camera in Teams specifically (even while the same camera works fine in other apps).
4. Wrong Camera Selected in Teams Settings
If you have more than one camera connected (a built-in laptop camera plus an external USB webcam, for example), Teams may default to the wrong one, making it look like your camera “isn’t working” when it’s simply pointed at the wrong device.
Step-by-Step Fix
Step 1: Close Other Apps Using the Camera
Close Zoom, Skype, any open browser tabs with video calls, and any camera-related software running in the background. Then reopen Teams and try your camera again.
Step 2: Check Camera Permissions (Windows)
- Open Settings → Privacy & Security → Camera.
- Make sure “Camera access” is turned on.
- Scroll down and confirm Microsoft Teams is allowed under “Let apps access your camera.”
Step 3: Check Camera Permissions (macOS)
- Open System Settings → Privacy & Security → Camera.
- Confirm the toggle next to Microsoft Teams is switched on.
- If Teams isn’t listed at all, quit and reopen Teams once — macOS usually adds it to the list the next time it requests camera access.
Step 4: Select the Correct Camera in Teams
In a Teams meeting or call, click the three-dot menu → Settings → Devices, and confirm the correct camera is selected from the dropdown. If you have multiple cameras, try switching between them to identify which one is functional.
Step 5: Update Your Camera Driver
- Right-click the Start button and open Device Manager.
- Expand “Cameras” (or “Imaging devices”).
- Right-click your camera and select “Update driver,” then “Search automatically for drivers.”
Step 6: Restart Your Device
A full restart clears any background process that might still be holding onto the camera even after you’ve closed the app that opened it — this alone resolves a surprising number of “camera stuck” cases.
Step 7: Test the Camera Outside Teams
Open your operating system’s built-in Camera app (Camera on Windows, Photo Booth on Mac). If the camera doesn’t work there either, the issue is hardware or driver-related rather than specific to Teams.
Frequently Asked Questions
My camera works in Zoom but not Teams — why?
This usually points to an app-specific permission issue rather than a hardware problem. Recheck Step 2 or Step 3 specifically for Teams, since each app requests camera permission separately.
Why is my Teams camera showing a black screen instead of an error?
A black screen with no error message typically means Teams technically has access but the camera feed itself isn’t coming through — most often an outdated driver (Step 5) or another app quietly holding the camera (Step 1).
Does using Teams in a browser fix camera issues?
Sometimes — the browser version of Teams uses your browser’s camera permissions instead of the desktop app’s, so it’s a useful way to isolate whether the issue is with the Teams desktop app specifically.
