Where to find your camera and turn it on

Your computer camera is almost always already on at the hardware level — the switch you need to flip is in your operating system or in the app you want to use it with. On Windows, go to Settings > Privacy & Security > Camera and make sure the toggle next to "Camera access" is turned on (it should be blue). On Mac, open System Settings > Privacy & Security > Camera and check that the apps you want to use have a checkmark next to their names.

If you see a physical slider or cover over your camera lens, slide it to uncover the lens. Some laptops and external cameras have a small physical switch; check the sides or back of your device. Once the system setting is on, your camera is ready to use in any app that requests it.

The first time an app tries to use your camera, your operating system will ask for permission. Click Allow or Yes to grant access. You can change these permissions later by going back to the same Privacy & Security menu.

Key Takeaways

  • On Windows, enable camera access in Settings > Privacy & Security > Camera by turning on the toggle switch.
  • On Mac, go to System Settings > Privacy & Security > Camera and check the box next to each app that needs camera permission.
  • If your camera has a physical cover or slider, move it to uncover the lens before using the camera.
  • When an app first asks to use your camera, click Allow to grant permission; you can revoke it anytime in the same settings menu.

Checking if your camera is actually connected

If you turned on the system setting but your camera still does not work, the camera may not be recognized by your computer. On Windows, right-click the Start button, select Device Manager, and look for Cameras in the list. Click the arrow next to it to expand. If you see your camera listed with no warning symbol, it is connected. If you see a yellow triangle or exclamation mark, the driver may need updating.

On Mac, open System Information (click the Apple menu, then About This Mac, then System Report). Click USB in the left sidebar and look for your camera in the list. If it appears, your camera is connected to the computer.

If your camera does not appear in Device Manager or System Information, the cable may be loose, the USB port may be damaged, or the camera itself may not be working. Try unplugging and replugging the camera into a different USB port. If it still does not show up, the camera may need repair or replacement.

Updating camera drivers on Windows

A camera driver is the software that lets Windows talk to your camera. If your camera appears in Device Manager with a warning symbol, the driver may be outdated or missing. Right-click on your camera in Device Manager and select Update driver. Choose Search automatically for updated driver software and let Windows search online for the latest version.

If Windows cannot find an updated driver, visit the camera manufacturer's website (look for the brand name on your camera or in Device Manager). Search their support page for your camera model and read the driver file for Windows. Run the installer and follow the on-screen steps. Restart your computer when prompted.

After updating the driver, go back to Settings > Privacy & Security > Camera and make sure the toggle is still on. Your camera should now work in any app that requests it.

Using your camera in common apps

Once your camera is turned on in system settings, you can use it in video call apps like Zoom, Google Meet, Microsoft Teams, or Skype. Open the app, start a call or meeting, and look for a camera icon (usually near the microphone icon). Click it to turn on your camera. The first time you use the app, it will ask for permission — click Allow.

In photo or video apps like the built-in Camera app on Windows or Photo Booth on Mac, straightforward open the app and your camera will set up automatically. You may see a preview of what the camera sees on your screen. On Windows, the Camera app is in the Start menu. On Mac, open Spotlight (press Command + Space), type "Photo Booth," and press Enter.

If an app says your camera is not available even though you turned it on in settings, close the app completely and reopen it. If the problem persists, restart your computer. Sometimes a camera permission gets stuck and a restart clears it.

Troubleshooting a camera that turns off by itself

If your camera turns on but then stops working after a few minutes, a power-saving setting may be turning it off. On Windows, go to Settings > System > Power & battery and check your power plan. If you are on battery power, your computer may be cutting power to USB devices to save energy. Plug in your laptop or change the power plan to High Performance to keep the camera running.

Another common cause is an app conflict. If two apps try to use the camera at the same time, one may shut down. Close all other apps that might use the camera (like Zoom, Skype, or your browser if you were in a video call) and try again with just one app open.

If the camera still cuts out, the cable connecting it to your computer may be loose or damaged. Unplug it, wait 10 seconds, and plug it back in firmly. If you are using an external camera, try a different USB port. If the problem continues, the camera hardware itself may be failing and may need professional repair.

When to call a professional

If you have turned on the camera in system settings, checked Device Manager or System Information and the camera appears, updated drivers, and the camera still does not work, the hardware may be faulty. Contact the camera manufacturer's support line or take your computer to a repair shop. If it is a built-in laptop camera, the manufacturer (Dell, HP, Lenovo, Apple, etc.) can advise whether repair is worth the cost.

If you are not comfortable opening Device Manager or updating drivers, a local computer repair shop can do this for you in 30 minutes to an hour. The cost is usually between $50 and $150 depending on your location and the shop.

Frequently Asked Questions

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

A black screen usually means the lens is covered (check for a physical slider or cap), the camera driver is outdated, or another app is already using the camera. Try uncovering the lens, closing other apps, and restarting your computer. If it still shows black, update the camera driver through Device Manager (Windows) or the manufacturer's website.

Can I turn off my camera completely so no app can use it?

Yes. On Windows, go to Settings > Privacy & Security > Camera and turn off the toggle next to "Camera access." On Mac, go to System Settings > Privacy & Security > Camera and uncheck all apps. You can also cover the lens with a physical slider or sticker for extra security.

My camera works in one app but not another. What should I do?

The app that is not working may not have permission to use the camera. On Windows, go to Settings > Privacy & Security > Camera and scroll down to see which apps have permission. Turn on the toggle for the app you want to use. On Mac, check System Settings > Privacy & Security > Camera and add the app to the list if it is missing.

Is my camera always recording even when I am not using it?

No. Your camera only turns on when an app requests it. You can see which apps have permission in your Privacy & Security settings. If you want to be extra cautious, cover the lens with a physical slider or sticker, or disable camera access entirely in system settings.

What if I do not know the brand or model of my camera?

On Windows, open Device Manager, expand Cameras, and the name of your camera will be listed. On Mac, open System Information, click USB, and look for your camera. If it just says "USB Camera" or "Integrated Camera," it is likely a generic model built into your laptop. Search your laptop brand (Dell, HP, Lenovo, Apple) plus "camera driver" on their support website.
