The fastest way to check your webcam

Open your operating system's built-in camera app. On Windows 10 or 11, search for "Camera" in the Start menu and click the app. On Mac, open Launchpad, search for "Photo Booth," and launch it. On Linux, open the Activities menu and search for "Cheese" or your distribution's camera utility. If the app opens and shows a live video feed of your face or surroundings, your webcam hardware is working and your operating system recognizes it.

If the app opens but shows a black screen, or if it says "no camera found," your webcam may not be properly connected, may lack the right drivers, or may be disabled in your system settings. Do not assume the hardware is broken yet—most webcam problems are software or connection issues, not physical failure.

Key Takeaways

  • Your operating system's built-in camera app is the fastest way to test whether your webcam works without installing anything.
  • A black screen or "no camera found" message usually means a driver is missing, the webcam is disabled in settings, or the USB cable is loose—not that the hardware is broken.
  • Check Device Manager on Windows or System Report on Mac to see whether your computer recognizes the webcam at all.
  • If your webcam works in the system app but not in a specific program like Zoom or Teams, the program may not have permission to use the camera.
  • Unplugging and replugging a USB webcam, or restarting your computer, solves most webcam problems that are not hardware failures.

Check if Windows recognizes your webcam in Device Manager

On Windows, open Device Manager by right-clicking the Start button and selecting "Device Manager," or by searching for it in the Start menu. Look for a category called "Cameras" or "Imaging devices." Click the arrow next to it to expand the list. If you see your webcam listed there with no warning icon (yellow triangle), Windows recognizes it and the drivers are installed.

If the category does not exist, or if your webcam appears with a yellow warning triangle or exclamation mark, the drivers are missing or corrupted. Right-click the device and select "Update driver," then choose "Search automatically for updated driver software." Windows will search online and install the correct driver if it finds one. After the driver installs, restart your computer and test the camera app again.

If Device Manager shows no camera at all, the webcam may not be plugged in properly. For USB webcams, unplug the cable from your computer, wait five seconds, and plug it back in. For built-in laptop webcams, the issue is usually a disabled setting or a missing driver, not a loose connection.

Check if Mac recognizes your webcam in System Report

On Mac, click the Apple menu, select "About This Mac," then click "System Report." In the left sidebar, click "Hardware" and look for "Camera" in the list. If your webcam appears there, macOS recognizes it. If it does not appear, the hardware may not be connected or recognized by the system.

If your Mac has a built-in camera and it does not appear in System Report, restart your computer. If it still does not appear after restart, the camera may be disabled in a firmware setting or may have a hardware problem. If you have a USB webcam that does not appear, unplug it, wait five seconds, and plug it back in to a different USB port. Then check System Report again.

Test your webcam in a video call app

Open Zoom, Microsoft Teams, Google Meet, or another video call app you use regularly. Look for a settings or preferences menu, usually represented by a gear icon. Find the "Camera" or "Video" section. The app should show a list of available cameras. Select your webcam from the list if it is not already selected. You should see a live preview of your camera feed in the settings window.

If your webcam does not appear in the list, the app does not have permission to use it. On Windows, go to Settings > Privacy & Security > Camera and make sure the toggle for the app is turned on. On Mac, go to System Preferences > Security & Privacy > Camera and check that the app is listed and permitted. After you grant permission, restart the app and check the camera settings again.

What to do if the camera app works but video calls do not

If your system camera app shows a live feed but Zoom, Teams, or another video app shows a black screen or says no camera is available, the problem is almost always a permission issue, not a hardware failure. The app does not have permission to access your webcam. Follow the permission steps in the section above for your operating system.

If you have already granted permission and the app still does not see the camera, try closing the app completely and opening it again. If that does not work, restart your computer. If the problem persists after restart, uninstall the app and read the latest version from the official website. Older versions sometimes have bugs that prevent them from seeing the camera even when permission is granted.

Troubleshoot a USB webcam that is not recognized

Unplug the webcam from your computer. Wait five seconds. Plug it into a different USB port on your computer—not a USB hub, but a port directly on your computer or laptop. Wait 10 seconds for the system to recognize it. Open your camera app and test it again.

If the webcam still does not work, the USB port itself may be faulty. Try plugging it into another port. If it works in one port but not another, that port is broken and you should avoid using it. If the webcam does not work in any port, check whether the cable is damaged—look for bent pins, fraying, or visible damage. If the cable looks intact, the webcam hardware may be faulty and may need to be replaced.

Restart your computer as a first step

Before you spend time troubleshooting, restart your computer. Many webcam problems—drivers not loading, permissions not explore, USB devices not being recognized—are solved by a straightforward restart. Close all your programs, shut down your computer completely, wait 10 seconds, and turn it back on. Then test your webcam again in the system camera app.

A restart is especially useful if your webcam worked before but suddenly stopped working, or if you just installed a new driver or updated your operating system. It gives the system time to fully load drivers and explore permission changes.

Frequently Asked Questions

Why does my webcam work in the camera app but not in Zoom?

Zoom does not have permission to use your camera. On Windows, go to Settings > Privacy & Security > Camera and turn on the toggle for Zoom. On Mac, go to System Preferences > Security & Privacy > Camera and add Zoom to the list. Close Zoom completely and open it again. The camera should now appear in Zoom's settings.

My webcam shows a black screen in the camera app. Is it broken?

Not necessarily. A black screen usually means the driver is missing, the camera is disabled in settings, or the USB cable is loose. Try unplugging and replugging the cable, restarting your computer, or updating the driver in Device Manager. If it still shows black after these steps, the hardware may be faulty.

How do I know if my webcam driver is installed?

On Windows, open Device Manager, find "Cameras" or "Imaging devices," and expand it. If your webcam is listed with no warning icon, the driver is installed. On Mac, open System Report, click Hardware, and look for Camera in the list. If it appears, the system recognizes it.

Can I test my webcam without opening an app?

Not directly, but the system camera app is the simplest test. It is built into your operating system and requires no installation. If you want a second opinion, you can test in a video call app like Google Meet, which also shows a live preview in settings before you join a call.

What should I do if my webcam is not listed in Device Manager?

For a USB webcam, unplug it, wait five seconds, and plug it back in. For a built-in laptop camera, restart your computer. If it still does not appear, the drivers may be missing. Visit the manufacturer's website, read the latest driver for your webcam model, and install it manually. Then restart and check Device Manager again.
