The fastest way to test your laptop camera
Open your operating system's built-in camera app — it will show you a live feed from your webcam in seconds. On Windows 10 and 11, search for "Camera" in the Start menu and click the app. On Mac, open Photo Booth (in Applications > Utilities) or use FaceTime and select your camera from the Video menu. On Linux, open Cheese or Snapshot, both of which display your camera feed when ready. If you see yourself or your surroundings on screen, your camera works.
If the app opens but shows a black screen or "no camera found" message, your camera may be disabled, blocked by another program, or not recognized by your system. The sections below walk through each possibility and how to fix it.
Key Takeaways
- The Camera app (Windows), Photo Booth (Mac), or Cheese (Linux) will show whether your webcam is working in under 30 seconds.
- A black screen usually means your camera is disabled in settings, blocked by privacy controls, or in use by another program.
- Check Device Manager on Windows or System Report on Mac to confirm your camera hardware is recognized by your computer.
- Restarting your browser or video app often fixes temporary camera failures without requiring driver updates.
- If your camera works in one app but not another, the problem is software permissions, not the hardware itself.
Test your camera in Windows 10 and 11
Press the Windows key, type "Camera," and click the Camera app when it appears. The app will request permission to use your webcam — click "Yes" when prompted. Within a few seconds, you should see a live video feed of what your camera sees. If you see video, your camera is working. Take a screenshot or a test photo by clicking the camera icon in the app to confirm the image captures correctly.
If the app opens but shows a black screen, check whether another program is using your camera. Close your browser, video conferencing apps (Zoom, Teams, Discord), and any other software that might access the camera. Then reopen the Camera app. If video appears after closing other apps, one of them had exclusive access to your camera.
If you still see black, go to Settings > Privacy & Security > Camera. Make sure the toggle next to "Camera access" is turned on. Then scroll down and confirm that the Camera app itself has permission enabled. If the Camera app is not listed, toggle camera access off and back on to reset it.
Test your camera on Mac
Open Finder, go to Applications, then Utilities, and double-click Photo Booth. The app will display a live preview from your camera within seconds. You should see yourself or your surroundings in the center window. If you see video, your camera is working correctly.
If Photo Booth shows a black screen or says "No Camera Found," check System Preferences > Security & Privacy > Camera. Confirm that Photo Booth (or whichever app you want to use) is listed and has permission enabled. If the app is not listed, click the lock icon to unlock settings, then click the plus button to add the app manually.
Another quick test is to open FaceTime. Click Video in the menu bar, then look for your camera name in the dropdown. If your camera appears in the list and you see a preview, your hardware is working. The issue is then a permissions problem with the specific app you were testing.
Test your camera on Linux
Open your process menu and search for "Cheese" or "Snapshot" — both are standard camera testing tools on most Linux distributions. Click to open the app. You should see a live video feed from your webcam within a few seconds. If video appears, your camera is working.
If the app opens but shows no video, open a terminal and run the command ls /dev/video* to check whether your system recognizes a camera device. If you see output like /dev/video0, your camera hardware is detected. The problem is then a permissions or driver issue. Run groups to see your user groups, and confirm that your user is in the "video" group. If not, add yourself with sudo usermod -a -G video $USER, then log out and back in.
Check whether your camera is disabled in Device Manager (Windows)
Right-click the Start button and select Device Manager. Look for "Cameras" or "Imaging devices" in the list and click the arrow to expand it. Your camera should be listed by name — often something like "Integrated Camera" or your manufacturer's name. If you see a yellow exclamation mark or a down arrow next to it, your camera is disabled.
Right-click the camera name and select "Enable device." Windows will attempt to turn it back on. Wait 10 seconds, then try the Camera app again. If your camera still does not appear in Device Manager at all, your hardware may not be recognized. Restart your laptop and check again — sometimes a restart forces Windows to re-detect hardware.
If your camera appears in Device Manager but the Camera app still shows black, the hardware is recognized but software is blocking it. Go back to Settings > Privacy & Security > Camera and toggle camera access off and on again to reset permissions.
Check System Report on Mac
Click the Apple menu, select About This Mac, then click System Report. In the left sidebar, click USB (under Hardware) to see all connected USB devices. Look for your camera in the list — it may be labeled "Integrated Camera," "FaceTime Camera," or your manufacturer's name. If your camera appears here, your Mac recognizes the hardware.
If your camera does not appear in the USB list, restart your Mac and check again. If it still does not show up after a restart, your camera hardware may not be connected properly or may be faulty. If your camera does appear in System Report but Photo Booth or FaceTime shows no video, the problem is a permissions or software issue, not the hardware.
Test your camera in a web browser
Open any web browser and go to a camera testing site such as webcamtests.com or codebeautify.org/webcam-test. Click "Allow" when the browser asks for camera permission. The site will display a live feed from your webcam. If you see video, your camera and browser permissions are both working.
If the browser shows a black screen or says "camera not found," close all other apps that might be using your camera, then refresh the page. If video appears after closing other apps, another program had exclusive access. If the browser still shows black after closing everything else, go to your browser settings and check camera permissions. In Chrome, Firefox, and Edge, click the lock icon in the address bar, find Camera in the permissions list, and make sure it is set to "Allow."
If your camera works in a browser but not in a specific app like Zoom or Teams, the problem is that app's permissions, not your camera hardware. Check that app's settings to confirm camera access is turned on.
Restart your camera driver (Windows)
Right-click the Start button and open Device Manager. Find your camera under Cameras or Imaging devices, right-click it, and select "Uninstall device." A dialog will ask whether to delete the driver software — check the box and click Uninstall. Restart your laptop. Windows will automatically reinstall the camera driver when it boots back up.
After your laptop restarts, open the Camera app and test again. A fresh driver installation often fixes black-screen problems that persist after checking permissions and closing other apps. If your camera still does not work after a driver reinstall and restart, the hardware itself may be faulty.
Frequently Asked Questions
Why does my camera work in Zoom but not in Teams?
Each app manages camera permissions separately. Open Teams settings, go to Privacy, and confirm Camera is turned on. If it is already on, close Teams completely (including background processes), wait 10 seconds, and reopen it. If the camera still does not work in Teams but works in Zoom, Teams may need a permissions reset — uninstall and reinstall the app.
My camera shows video but the image is upside down or sideways. Is it broken?
No. Your camera hardware is working fine. The image orientation is a software setting in whichever app you are using. Check that app's video settings for a rotation or flip option. Most video conferencing apps have this under Settings > Video or Camera. You can also physically rotate your laptop or external camera if it is mounted incorrectly.
The Camera app says "We can't find your camera" but Device Manager shows it. What do I do?
Go to Settings > Privacy & Security > Camera and toggle camera access completely off. Wait 10 seconds, then toggle it back on. This resets Windows' camera permissions. Then open the Camera app again. If it still fails, restart your laptop — sometimes Windows needs a reboot to recognize a camera after a permissions reset.
Can I test my camera without opening an app?
Yes. Most operating systems show a camera indicator light when any app accesses your camera. If you open your browser to a camera test site and see the light turn on, your camera is working even if the page shows black. The black screen is then a browser permissions issue, not a camera hardware problem. Check your browser's camera permissions in settings.
My external USB camera is not showing up anywhere. How do I know if it is plugged in correctly?
Unplug the camera, wait 10 seconds, and plug it back in. Then check Device Manager (Windows) or System Report (Mac) again. If the camera still does not appear, try a different USB port — some ports may not provide enough power. If it appears in Device Manager or System Report but no app can access it, restart your computer. If it never appears after a restart, the camera may be faulty or incompatible with your system.
