The fastest way to turn your webcam on depends on what you're using it for

Most webcams built into laptops turn on automatically when you open an app that needs video—like Zoom, Google Meet, or Skype. If nothing happens, or if you're using an external webcam, you may need to flip a physical switch, plug it in, or enable it in your system settings. The steps differ between Windows and Mac, and between built-in and external cameras.

Before you start troubleshooting, check whether your camera has a physical on/off switch or a lens cover. Some external webcams have a small toggle on the back or bottom. If your laptop has a sliding cover over the camera lens, open it. If you see a light next to the camera lens, it's already powered on.

Key Takeaways

  • Most built-in laptop webcams turn on automatically when you open Zoom, Google Meet, Skype, or another video app.
  • External USB webcams need to be plugged into a USB port and may require driver software to work on Windows.
  • On Windows, you can check whether your camera is enabled in Settings under Privacy & Security, then Camera.
  • On Mac, check System Settings under Privacy & Security, then Camera to see which apps have permission to use it.
  • If your camera still won't turn on after checking these steps, restart your computer and try again.

Turning on a built-in laptop camera on Windows

Open the app you want to use video in—Zoom, Google Meet, Teams, or Skype. When the app asks for camera permission, click Allow or Yes. The camera should light up and show your face on screen.

If the app doesn't ask for permission, or if you see a message that says the camera is blocked, go to Settings (press the Windows key and type "Settings"). Click Privacy & Security on the left side. Scroll down and click Camera. Make sure the toggle at the top that says Camera access is turned on (it should be blue). Then scroll down to find the app you want to use and make sure its toggle is also on.

If you don't see your camera listed in Settings at all, your camera driver may not be installed. Restart your computer and try again. If it still doesn't appear, check your laptop manufacturer's support website for camera driver downloads.

Turning on a built-in camera on Mac

Open the app you want to use video in. When it asks for camera permission, click Allow. Your camera should turn on and show your face.

If the app doesn't ask, or if you see a permission error, open System Settings (click the Apple menu in the top left, then System Settings). Click Privacy & Security on the left. Scroll down and click Camera. You'll see a list of apps. Make sure the toggle next to the app you want to use is turned on (it should be green).

If you don't see your camera working even after allowing permission, restart your Mac and try again. Restarting fixes most camera problems on Mac.

Setting up an external USB webcam on Windows

Plug the webcam into any available USB port on your computer. Wait 10 to 15 seconds for Windows to recognize it. A notification may appear saying a new device was found.

Open the app you want to use video in and select your camera from the camera menu. On Zoom, for example, click the arrow next to the camera icon during a call and choose your external webcam from the list. On Google Meet, click the three dots, then Settings, then Camera, and select your webcam.

If your camera doesn't appear in the app's camera menu, Windows may not have recognized it. Unplug it, wait 10 seconds, and plug it back in. If it still doesn't work, check the webcam manufacturer's website to see whether you need to read and install driver software. Some older or specialized webcams require drivers before Windows will use them.

Setting up an external USB webcam on Mac

Plug the webcam into any available USB port. Mac usually recognizes external cameras right away without needing driver software.

Open the app you want to use video in. The camera should appear in the app's camera menu automatically. If you need to choose it, click the menu in the app's settings and select your external webcam by name.

If your camera doesn't show up, unplug it and plug it back in. Restart your Mac if it still doesn't work. Most external webcams work on Mac without any extra software, but check the manufacturer's website if the camera is older or specialized.

Checking for physical switches and covers

Before you change any settings, look at your camera itself. Many laptops have a sliding lens cover over the built-in camera—slide it to the side to open it. Some external webcams have a physical on/off switch on the back or bottom. Check your camera's manual or the manufacturer's website if you're not sure.

Look for a small light next to the camera lens. If the light is on, the camera is powered. If there's no light and the camera still won't work, the camera may be disabled in your system settings or the app may not have permission to use it.

What to do if your camera still won't turn on

Restart your computer. This fixes most camera problems and takes only a few minutes. After restarting, open your video app again and check whether the camera works.

If restarting doesn't help, unplug any external cameras and plug them back in. On Windows, go to Settings > Privacy & Security > Camera and make sure Camera access is turned on. On Mac, go to System Settings > Privacy & Security > Camera and check that your app has permission. If you still see no camera listed, your camera hardware may not be working and you may need to contact your computer manufacturer or replace the camera.

Frequently Asked Questions

Why does my camera show a black screen even though it's turned on?

A black screen usually means the app has permission to use the camera but something is blocking the lens. Check for a lens cover and slide it open. Make sure nothing is physically covering the camera. If the lens is clear, try closing the app completely and opening it again. Restarting your computer also often fixes black screen problems.

Can I turn my camera on and off without unplugging it?

Yes. On Windows, go to Settings > Privacy & Security > Camera and toggle Camera access off to disable all cameras, or toggle off individual apps. On Mac, go to System Settings > Privacy & Security > Camera and toggle off the apps you don't want to use the camera. You can also close the app that's using the camera, which stops the camera from running without disabling it system-wide.

Do I need to install software for an external webcam to work?

Most modern external webcams work without any software on both Windows and Mac. Plug them in and they're ready to use. Older webcams or specialized cameras may need driver software. Check the box your camera came in or the manufacturer's website to see if drivers are required.

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

The app that isn't working probably doesn't have permission to use your camera. On Windows, go to Settings > Privacy & Security > Camera and make sure the toggle next to that app is on. On Mac, go to System Settings > Privacy & Security > Camera and turn on the toggle for that app. You may need to restart the app after changing permissions.

Is it safe to leave my webcam on all the time?

It's safe, but many people cover their camera lens when they're not using it for privacy. You can also disable camera access in your system settings when you don't need it. Disabling it in settings stops any app from using the camera without your knowledge.
