1. Fix camera permissions
In your browser
Click the site-information icon at the left of the address bar (a lock, a sliders icon or a camera icon, depending on your browser), set Camera to Allow and reload the page. In Chrome you can also open Settings → Privacy and security → Site settings → Camera and remove the site from the blocked list.
On Windows 11 and 10
- Windows 11: open Settings → Privacy & security → Camera and turn on Camera access, Let apps access your camera and Let desktop apps access your camera.
- Windows 10: open Settings → Privacy → Camera and turn on Allow apps to access your camera and Allow desktop apps to access your camera.
- Browsers count as desktop apps. Restart the browser afterwards.
On a Mac
Open System Settings → Privacy & Security → Camera, switch on your browser, then quit it completely (Cmd+Q) and reopen it. Safari: macOS doesn't list Safari here — open Safari → Settings → Websites → Camera (and Microphone) and set this site to Allow.
2. Free a camera that is "in use"
Many apps and drivers lock the camera so only one app can use it at a time. Close Zoom, Teams, Discord, OBS, FaceTime and any other browser tab that uses the camera — check the system tray (Windows) or menu bar (Mac) too. On Windows you can open Settings → Privacy & security → Camera to see which apps used it recently.
Still busy? Restart the computer. A crashed camera driver often only recovers after a restart.
3. Make the camera show up
- Laptop: look for a physical privacy shutter above the screen, or a key with a camera (or crossed-out camera) icon on the keyboard — which key varies by brand, often used with Fn. Lenovo, HP and Dell laptops often have one of these.
- External webcam: plug it straight into the computer instead of a hub, try another USB port, and try another cable if it has one.
- Windows: open Device Manager → Cameras (or Imaging devices). If the camera has a warning icon, right-click → Update driver, or Uninstall device and restart to reinstall it. On Windows 11 (22H2 or later), also make sure it isn't disabled under Settings → Bluetooth & devices → Cameras.
- Mac: the built-in FaceTime camera has no driver to install. If it is missing, restart the Mac; on Intel Macs, resetting the SMC can help.
4. Camera on but the screen is black
If the test opens the camera but the picture quality check says Almost blank, something is covering the lens — a shutter, sticker or tape. If the picture is just very dark, see why your webcam is dark or grainy.
Works here but not in your meeting app?
If the test above shows your picture, the camera itself is fine. The problem is the settings in the app: pick the same camera in its video settings and make sure nothing else is using the camera. See our guides for Zoom, Microsoft Teams and Google Meet.
