Start by checking if your webcam is plugged in and recognized
Most laptops have a built-in webcam above the screen. If you have an external webcam, plug it into a USB port on your computer. Wait a few seconds for your operating system to recognize it — you should not need to install anything for modern webcams.
On Windows, open Settings, go to Privacy & Security, then Camera. You will see a list of apps allowed to use the camera. Make sure Camera access is turned on at the top. On Mac, open System Settings, click Privacy & Security, then Camera. On Chromebook, the camera is usually ready to use once you log in.
If your webcam does not appear in these settings, restart your computer. If it still does not show up, the USB port may be faulty — try a different port, or test the webcam on another computer to confirm it works.
Key Takeaways
- Built-in webcams are already in your laptop; external ones plug into USB and are recognized automatically on modern systems.
- Windows and Mac require you to turn on camera access in Privacy settings before any app can use it.
- Video calling apps like Zoom, Google Meet, and Skype ask for camera permission the first time you use them — click Allow.
- If your webcam is not working, restart your computer first, then check that the app has permission and the camera is not in use by another program.
- Most webcam problems are solved by restarting or checking privacy settings; hardware failure is rare.
Allow apps to use your camera through privacy settings
When you open a video calling app like Zoom, Google Meet, Skype, or Microsoft Teams for the first time, it will ask for permission to use your camera. Click Allow or Yes. If you accidentally clicked Deny, you need to give permission again through your system settings.
On Windows, go to Settings > Privacy & Security > Camera. Scroll down to App permissions and turn on the toggle for the specific app you want to use. On Mac, go to System Settings > Privacy & Security > Camera and check the box next to the app name. On Chromebook, the app will ask again the next time you open it.
Some apps also have their own camera settings inside the program. Open the app, look for Settings or Preferences (often a gear icon), and find the Camera or Video section. You can usually choose which camera to use if you have more than one plugged in.
Test your camera before a video call
Most video calling apps have a settings or preview screen where you can see yourself before you join a call. In Zoom, open the app and look for Settings or Preferences. Under Video, you will see a preview of what your camera sees. In Google Meet, start a new meeting and you will see a preview before you click Join now. In Skype, go to Settings > Audio devices and you will see a camera preview.
Check that you can see yourself clearly, that the lighting is good, and that the camera is pointing at your face. If the image is upside down or sideways, your app may have a rotate option in the video settings. If the image is very dark, move closer to a window or turn on a light in front of you — avoid sitting with a bright window behind you, as that will make your face too dark.
If you see a black screen or no image at all, the camera may be in use by another app. Close other video apps, web browsers with camera access, or screen recording software. Then restart the app you want to use and try again.
Adjust camera position and lighting for video calls
Position your camera at eye level or slightly above. If your laptop is on a desk, prop it up with a book or stand so the camera points at your face, not up your nose or down at the top of your head. External webcams can be mounted on top of your monitor or on a tripod.
Lighting matters more than camera quality. Sit facing a window or lamp so light falls on your face, not behind you. If you are backlit (light behind you), your face will appear as a dark silhouette. Avoid harsh shadows by using soft, diffused light — a desk lamp with a white shade works well. If you are on a video call and your image looks too dark, move closer to the light source or ask the other person if they can see you clearly.
Keep your background straightforward and uncluttered for professional calls. If you want to hide your background, many apps offer a blur or virtual background feature. In Zoom, click the up arrow next to Stop Video during a call and select Choose a virtual background. In Google Meet, click Effects (the smiley face icon) and select a background blur or image.
Troubleshoot a webcam that is not working
If your camera works in one app but not another, the problem is usually permissions. Check that the app has camera access in your system privacy settings (see the section above). If the app is new, restart it — sometimes it needs to ask for permission again.
If your camera does not work in any app, restart your computer first. This solves most webcam problems. After restart, open your privacy settings and confirm camera access is turned on. Then try the app again.
If restart does not help, check whether another app is using the camera. On Windows, open Task Manager (press Ctrl + Shift + Esc), look at the list of running apps, and close any that might use the camera — screen recording software, other video apps, or web browsers with camera tabs open. On Mac, open Activity Monitor (search for it in Spotlight), look for camera-related processes, and click the X to close them. Then try your video app again.
If the camera still does not work, unplug an external webcam and plug it back in, or restart your computer again. If you have tried all of these steps and the camera still does not work, the hardware may be faulty — test it on another computer if you can, or contact the manufacturer.
Use your webcam for screen recording and photos
You can record video of yourself or your screen using built-in tools. On Windows 10 and 11, open the app you want to record, press Windows key + G to open Game Bar, and click the record button (or press Windows key + Alt + R). This records your screen and microphone audio. On Mac, press Shift + Command + 5 to open the screenshot and recording tool. You can record your entire screen or just a portion of it.
To take a photo with your webcam on Windows, search for Camera in the Start menu and open the Camera app. Click the camera icon to take a photo. On Mac, open Photo Booth (search for it in Spotlight) and click the camera icon. On Chromebook, open the Camera app from your app drawer.
If you want to record a video message to send to someone, use your video calling app. In Zoom, you can record a message without joining a call by opening the app, clicking New Meeting, and then clicking Record. In Google Meet, start a new meeting, click More options (three dots), and select Record this meeting. The video saves to your computer or cloud storage.
Disable your webcam when you are not using it
For privacy, you can cover your webcam with a small piece of tape or a webcam cover (sold cheaply online). This is a straightforward way to prevent accidental access. You can also disable camera access for specific apps in your privacy settings — go to Settings > Privacy & Security > Camera on Windows or System Settings > Privacy & Security > Camera on Mac, and turn off the toggle for apps you do not use.
If you want to disable the camera entirely, you can do so in Device Manager on Windows. Press Windows key + X, click Device Manager, find Imaging devices, right-click your camera, and select Disable device. To turn it back on, right-click it again and select Enable device. On Mac, there is no built-in way to disable the camera in settings, but you can use the physical cover or manage app permissions individually.
Frequently Asked Questions
Why does my webcam show a black screen?
A black screen usually means another app is using the camera, the camera does not have permission, or the camera is physically blocked. Close other apps that might use the camera, check privacy settings to confirm the app has permission, and make sure nothing is covering the camera lens. If the problem persists, restart your computer.
Can I use an external webcam instead of the built-in one?
Yes. Plug the external webcam into a USB port and wait a few seconds for it to be recognized. In your video app settings, you should see a dropdown menu to choose which camera to use. Select the external camera. You can also disable the built-in camera in Device Manager (Windows) if you prefer.
Why is my video upside down or sideways?
Some cameras have a rotation setting in the app. Open your video app settings, look for a Camera or Video section, and check for a rotate or flip option. If your app does not have this, you can rotate the video in your operating system settings or use a third-party tool.
Do I need to install drivers for my webcam?
Modern webcams work without drivers on Windows, Mac, and Chromebook. If you have an older external webcam, the manufacturer may provide drivers on their website. Check the box or manual that came with the camera, or search the manufacturer's name plus "drivers" online.
Can someone access my webcam without my permission?
On modern systems, apps must ask for permission before using your camera, and you can see which apps have access in your privacy settings. Malware could theoretically access your camera, so keep your operating system and apps updated, do not read files from untrusted sources, and use antivirus software. A physical cover over your camera is an extra layer of privacy.
