Where your webcam is located

Your laptop's webcam is almost always built into the top bezel of your screen — the narrow strip above the display. On most models, it sits dead center, though some laptops place it slightly off to one side. Look for a small circular or rectangular lens, usually black or dark gray, about the size of a pencil eraser.

If you cannot spot it by looking, your laptop may have a physical shutter that covers the lens when not in use. Slide or flip that shutter to the side and you will see the lens underneath. Some business laptops, particularly ThinkPads and Dell Latitudes, come with these shutters as a privacy feature.

A few older or budget laptops have external webcams that connect via USB, usually sitting on a stand in front of the screen. Check your laptop's original box or manual if you cannot find a built-in camera — it will tell you whether one came with your machine.

Key Takeaways

  • Your webcam is built into the top bezel of your screen, centered above the display on most laptops.
  • If you see a small shutter above the screen, slide it to reveal the lens underneath.
  • You can test whether your webcam works by opening the Camera app (Windows) or Photo Booth (Mac) without needing to install anything.
  • If your camera does not appear in video calls or apps, check Windows Settings or Mac System Preferences to see whether the app has permission to use it.
  • A small LED light next to the lens indicates the camera is actively recording.

How to test your webcam in Windows

Open the Start menu and type Camera. Click the Camera app to launch it. The app will ask permission to use your webcam the first time you open it — click Yes. You should see a live video feed of yourself within a few seconds.

If the Camera app shows a black screen or says "No camera found," your webcam may be disabled in your device settings. Go to Settings > Privacy & Security > Camera. Make sure the toggle at the top that says Camera is turned on. Then scroll down and check that the apps you want to use the camera with have their own toggles switched on.

If the toggle is already on but the camera still does not work, you may need to update or reinstall the camera driver. Go to Settings > System > Device Manager. Look for Cameras in the list, click the arrow to expand it, right-click your camera, and select Update driver. Windows will search for the latest version automatically.

How to test your webcam on Mac

Open Spotlight by pressing Command + Space, type Photo Booth, and press Enter. Photo Booth will launch and show a live preview of your camera feed. You should see yourself on screen within a few seconds.

If Photo Booth shows a black screen, go to System Preferences > Security & Privacy > Camera. You will see a list of apps that have requested camera access. Make sure Photo Booth (or the app you want to use) is checked. If it is not listed, the app has never asked for permission — open the app again and grant permission when prompted.

On newer Macs running Monterey or later, use System Settings instead of System Preferences. The path is System Settings > Privacy & Security > Camera. The process is the same.

Why your webcam might not show up in video calls

Even if your camera works in the Camera app, it may not appear in Zoom, Teams, Google Meet, or other video call software. This almost always means the app does not have permission to use your camera. Go back to your privacy settings and make sure the video call app is listed and toggled on.

Close the video call app completely, then reopen it. Many apps need to be restarted after you grant a new permission. If it still does not work, uninstall and reinstall the app — sometimes the permission system gets stuck.

If you are using a web browser for video calls instead of an app, the browser itself needs camera permission. In Chrome, go to Settings > Privacy and Security > Site Settings > Camera. In Safari on Mac, go to Safari > Settings > Websites > Camera. Add the video call website to the allowed list.

Physical signs your webcam is working

When your camera is in use, a small LED light (usually green or white) will illuminate next to the lens. This light is controlled by the hardware itself, not the software, so it is a reliable sign that the camera is actually recording. If you see the light on but no video appears in your app, the problem is with the app's settings or permissions, not the camera.

Some laptops have a keyboard shortcut to disable the camera entirely. Check your laptop's manual or function keys — you may see a camera icon with an X on one of the F keys. If you accidentally pressed this, press it again to re-enable the camera.

Troubleshooting a camera that worked before but stopped

If your webcam worked in the past but suddenly stopped, the most common cause is a Windows or Mac update that reset your privacy settings. Go back to your camera privacy settings and re-enable the camera and the apps that use it.

The second most common cause is a driver update that broke compatibility. In Windows, open Device Manager, find your camera under Cameras, right-click it, and select Roll back driver if that option appears. If it does not, try updating the driver instead — sometimes a newer version fixes the problem.

Restart your laptop after making any changes. Many camera issues resolve themselves after a reboot because the operating system needs to reinitialize the hardware connection.

Frequently Asked Questions

Can I cover my webcam for privacy?

Yes. You can use a small piece of tape, a sticky note, or buy a webcam cover slider online for a few dollars. Covering the lens completely blocks video but does not affect your ability to use other features. If your laptop has a physical shutter, use that instead — it is designed for this purpose.

What if I see a green dot in the corner of my screen?

On newer Macs, a green dot appears when any app is using your camera. On Windows 11, you may see a camera icon in the system tray. These are privacy indicators showing that something is actively recording. Check which app is using the camera by looking at your open windows or checking your privacy settings.

Does my laptop have to be plugged in to use the webcam?

No. Your webcam draws very little power and works on battery. It will function whether your laptop is plugged in or running on battery alone.

Can I use an external webcam instead of the built-in one?

Yes. Plug a USB webcam into any available USB port. Your operating system will recognize it automatically. In most video call apps, you can choose which camera to use in the settings — select the external camera from the dropdown menu.

Why is my webcam image upside down or mirrored?

Most video call apps mirror the image by default so it looks natural to you, like looking in a mirror. Some apps have a setting to turn off the mirror effect. Check the app's video settings or preferences. If the image is actually upside down (not mirrored), your camera may be mounted incorrectly — this is rare and usually only happens if someone physically rotated the camera inside the laptop.
