Why is my laptop camera not detected?

It may be switched off with a keyboard key, disabled in Device Manager, or blocked by privacy settings. Check each one, then restart the computer.

Why is my webcam blurry or grainy?

Low light makes webcams lower their frame rate and add noise. Face a window or lamp, wipe the lens, and choose a higher resolution in the app if it offers one.

How do I check my webcam's resolution?

Run the webcam test — it shows the resolution and frame rate your camera is actually delivering, plus the maximum it reports supporting.

Webcam not working? How to test and fix it

A webcam that won't turn on is almost always blocked, busy or physically covered. Test it first, then work through the fixes in order — most take under a minute.

Open Webcam Test

1. Test the webcam

Open the webcam test and press Start. If you see yourself, the camera works and the issue is in the app you're using — jump to step 5. If it fails, the test shows the error your browser reports, which points straight to the cause.

2. Check for a shutter or camera key

Many laptops have a sliding privacy shutter above the screen — slide it open.
Some keyboards have a camera on/off key, often an F-key with a camera icon. Press it and try again.
A black picture while the camera light is on usually means a shutter or cover.

3. Allow camera access

Browser: click the icon to the left of the address bar → Camera → Allow, then reload.
Windows 11: Settings → Privacy & security → Camera. Turn on Camera access, Let apps access your camera, and Let desktop apps access your camera.
macOS: System Settings → Privacy & Security → Camera. Enable your browser or call app, then restart it.
iPhone and iPad: Settings → Privacy & Security → Camera.

4. Free the camera and reconnect it

Close other apps that may be holding the camera — Zoom, Teams, OBS, virtual camera apps and other browser tabs.
Plug USB webcams directly into the computer instead of a hub, or try another port.
Windows: in Device Manager, open Cameras (or Imaging devices), make sure the webcam isn't disabled, and update the driver if it shows a warning.
Restart the computer to release a camera stuck in use by a crashed app.

5. Select the camera in your call app

Zoom: Settings → Video → Camera.
Microsoft Teams: Settings → Devices → Camera.
Google Meet: More options (⋮) → Settings → Video → Camera.
With more than one camera (say, a laptop camera and a USB webcam), make sure the right one is selected.
