The fastest way to test your webcam right now

Open your webcam app or video chat software and look for yourself on screen. On Windows, search for "Camera" in the Start menu and click the Camera app — it will show a live feed if the webcam works. On Mac, open Photo Booth (search for it in Spotlight) or FaceTime and allow camera access when prompted. If you see your face, your hardware is working.

If nothing appears, the camera may be disabled in your system settings, blocked by privacy controls, or not installed. The next steps depend on what you find.

Key Takeaways

  • The Camera app on Windows and Photo Booth on Mac are the quickest built-in tools to test whether your webcam is receiving power and connected to your system.
  • If your camera app shows a black screen or an error, check your privacy settings first — Windows and Mac both allow you to block camera access per app.
  • Device Manager on Windows and System Report on Mac will tell you whether your laptop recognizes the camera hardware at all.
  • A camera that worked before but stopped working is usually a driver issue on Windows or a privacy toggle on Mac, not a hardware failure.
  • If your system does not recognize the camera and you have tried restarting, the webcam may need replacement or professional repair.

Check privacy and permission settings on Windows

Windows 10 and 11 let you block camera access at the system level, even if the hardware works. Open Settings, go to Privacy & Security, then Camera. You will see a toggle for "Camera access" — make sure it is turned on. Below that, check the list of apps: if the app you want to use (Zoom, Teams, Chrome) has its toggle off, turn it on.

If the Camera app itself is blocked, you will see "We can't find a camera" even though the hardware exists. Turning on camera access in Settings will fix this. Restart the Camera app after you change the setting.

Check privacy and permission settings on Mac

Mac asks for permission the first time an app tries to use the camera. If you denied it by mistake, you can change it in System Settings. Go to Privacy & Security, then Camera. You will see a list of apps that have requested access. Find the app you want to use and make sure it is checked. If it is not listed, the app has never asked for permission — open the app and try to start a video call, and Mac will prompt you again.

If you see your camera listed but unchecked, click the checkbox to allow it. Close and reopen the app for the change to take effect.

Verify your camera is recognized in Device Manager (Windows)

If the Camera app shows an error or black screen even after checking privacy settings, your system may not recognize the hardware. Open Device Manager by right-clicking the Start button and selecting Device Manager. Look for "Cameras" in the list and click the arrow next to it to expand.

You should see your webcam listed by name — often something like "Integrated Camera" or the manufacturer name. If you see a yellow warning triangle or question mark next to it, the driver is not installed or is corrupted. If the Cameras section does not exist at all, Windows does not detect the hardware. Try restarting your laptop first — sometimes a restart fixes detection. If the problem persists after restart, the camera may need replacement.

Verify your camera is recognized on Mac

On Mac, open System Report to check whether the hardware is detected. Click the Apple menu, select About This Mac, then System Report. In the left sidebar, look for "Camera" under the Hardware section. If you see your camera listed with details like "Built-in Isight" or a model number, the hardware is recognized.

If the Camera section does not appear at all, Mac does not detect the webcam. Restart your Mac and check again. If it still does not appear, the camera may be disconnected internally or need repair. If the camera is listed but Photo Booth or FaceTime still shows a black screen, the issue is usually a driver or permission problem, not hardware failure.

Update or reinstall the camera driver on Windows

If Device Manager shows your camera with a warning icon, the driver needs updating. Right-click the camera name and select "Update driver." Windows will search for the latest version online. If an update is found, install it and restart your laptop.

If updating does not work, right-click the camera again and select "Uninstall device." Restart your laptop — Windows will automatically reinstall the driver. If the camera still shows an error after restart, visit the laptop manufacturer's support website (Dell, HP, Lenovo, etc.) and read the camera driver for your exact model. Install it manually and restart again.

Test your camera in a video call app

Sometimes the Camera app works but video call software does not recognize the camera. Open Zoom, Microsoft Teams, Google Meet, or Skype and look for a camera settings or preview option before you join a call. Most apps have a camera icon in the settings menu where you can select which camera to use and see a live preview.

If the preview is black or shows "No camera found," the app may not have permission. Go back to your system privacy settings and make sure that specific app is allowed to use the camera. If the app is already allowed and still shows no camera, try uninstalling and reinstalling the app — sometimes the permission cache gets stuck.

Frequently Asked Questions

Why does my camera work in one app but not another?

Each app needs separate permission to use the camera. Check your privacy settings and make sure the app you are trying to use is allowed. Also check that app's own settings — some apps like Zoom have an internal camera selector where you must choose which camera to use.

My camera worked yesterday but shows a black screen today. What changed?

A Windows update, privacy setting change, or app update often causes this. Restart your laptop first. Then check privacy settings to confirm the app still has camera permission. If permission is on but the screen is still black, try uninstalling and reinstalling the app.

Device Manager shows my camera but it still does not work. What do I do?

Update the driver through Device Manager or read the latest driver from your laptop manufacturer's website. If updating does not fix it, uninstall the device in Device Manager and restart — Windows will reinstall the driver automatically. If it still fails after restart, contact the manufacturer or a repair technician.

Can I tell if my camera is physically broken or just disabled in software?

If Device Manager recognizes the camera and privacy settings allow it, but you still see a black screen, the issue is usually software. If Device Manager does not show the camera at all even after restart, or if you see a yellow warning that persists after driver updates, the hardware may be damaged and need professional repair.

Do I need to unplug an external USB camera to use the built-in one?

No. If you have both, your system recognizes both. In your app settings, you can choose which camera to use. If an app defaults to the wrong one, open the app's camera settings and select the built-in camera from the dropdown menu.
