Where to find your camera and turn it on

Your computer camera is built into your device — usually at the top of your screen if you have a laptop, or attached to an external monitor if you use a desktop. To turn it on, you do not flip a physical switch. Instead, you open an process that uses the camera, and the camera activates automatically when that app launches.

The fastest way is to open your camera app. On Windows, search for "Camera" in the taskbar search box and click the Camera app. On Mac, open Spotlight (press Command + Space), type "Photo Booth" or "FaceTime", and press Enter. Either app will set up your camera when ready, and you will see a live preview of what the camera sees.

If your camera does not appear when you open an app, or if you see a black screen, the camera may be disabled in your system settings or blocked by privacy controls. The next sections walk through how to check and fix that.

Key Takeaways

  • Your computer camera turns on automatically when you open an app that uses it, such as the Camera app, Zoom, or FaceTime.
  • On Windows, search for "Camera" in the taskbar; on Mac, use Spotlight to find Photo Booth or FaceTime.
  • If the camera shows a black screen or does not work, check your privacy settings to make sure camera access is not blocked.
  • Some laptops have a physical camera shutter or a keyboard shortcut to disable the camera for privacy.

Check if your camera is disabled in Windows settings

Windows lets you turn camera access on or off for individual apps, and it also lets you disable the camera entirely from the system level. If your camera app opens but shows a black screen, start by checking the Device Manager.

Open the Start menu, type "Device Manager", and press Enter. Look for "Cameras" in the list. Click the arrow next to it to expand the category. If your camera is listed there and has a green checkmark, the hardware is working. If it has a red X or a yellow warning triangle, right-click it and select "Enable device".

If the camera is enabled in Device Manager but still does not work in your app, check your privacy settings. Open Settings, go to Privacy & Security, and select Camera. Make sure the toggle at the top that says "Camera access" is turned on. Then scroll down and check that the specific app you want to use (Zoom, Teams, or whatever you are trying) has the toggle switched on next to its name.

Check if your camera is disabled on Mac

Mac controls camera access through System Settings. Open System Settings, click Privacy & Security in the sidebar, then select Camera. You will see a list of apps that have asked for camera permission. Make sure the app you want to use has a checkmark next to it.

If the app is not listed, it has never asked for permission yet. Open the app and try to use the camera feature — it will prompt you to allow access. Click Allow, and the camera should work.

If your camera still does not work after checking these settings, restart your computer. Many camera issues resolve after a restart because the operating system resets its connection to the hardware.

Physical camera shutters and keyboard shortcuts

Some laptops have a physical shutter or cover over the camera that you can slide open and closed. Check the top bezel of your screen — if you see a small slider or button, that may be controlling whether light can reach the camera sensor. Slide it to the open position.

A few laptop models also have a keyboard shortcut to disable the camera. Check your laptop's manual or search online for your model number plus "disable camera" to see if yours has one. The shortcut is usually a function key (F1 through F12) combined with another key.

Test your camera in a video call app

Once your camera is on and working in the Camera app, test it in the app you actually plan to use — Zoom, Microsoft Teams, Google Meet, or FaceTime. Open the app, go to settings or preferences, and look for a Camera or Video section. You should see a preview of what your camera sees. If you see your face or the room behind you, the camera is working correctly.

If the preview is still black or blank, go back to your privacy settings and make sure that specific app has permission. Some apps require you to restart them after you grant permission before they can use the camera.

What to do if your camera is not listed in Device Manager or System Settings

If your camera does not appear anywhere in your system settings, the hardware may not be recognized by your operating system. This usually means a driver is missing or outdated.

On Windows, open Device Manager again and look for any item with a yellow warning triangle. Right-click it and select "Update driver". Choose "Search automatically for updated driver software" and let Windows search for and install the correct driver. After the driver installs, restart your computer.

On Mac, camera drivers are built into the operating system and cannot be updated separately. If your camera does not appear in System Settings, restart your computer. If it still does not appear after a restart, the camera hardware may be faulty and you may need to contact your computer manufacturer or a repair technician.

External cameras and USB connections

If you are using an external USB camera instead of a built-in one, plug it into an available USB port on your computer. Windows and Mac will recognize most USB cameras automatically and install drivers without asking you to do anything. Open your Camera app or video call app, and the external camera should appear in the list of available cameras.

If the external camera does not appear, try a different USB port. Some ports on older computers do not provide enough power for certain cameras. If you still have trouble, check the camera manufacturer's website for driver software specific to your model.

Frequently Asked Questions

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

A black screen usually means the app has permission to use the camera but the camera hardware is not responding. Restart your computer first. If that does not work, check Device Manager (Windows) or System Settings (Mac) to confirm the camera is enabled. You may also need to unplug and replug an external camera, or check that a physical camera shutter is not closed.

Can I turn off my camera without unplugging it?

Yes. On Windows, open Device Manager, find your camera, right-click it, and select "Disable device". On Mac, you cannot disable the hardware itself, but you can revoke camera permission from all apps in Privacy & Security. You can also use a physical camera shutter if your laptop has one.

Do I need to restart my computer every time I use the camera?

No. Once your camera is set up and working, it will turn on automatically whenever you open an app that uses it. You only need to restart if the camera stops working or if you have just installed a new driver.

What if my computer does not have a built-in camera?

You can buy an external USB camera and plug it into your computer. Most USB cameras work when ready without needing to install software. If your model requires a driver, the manufacturer will provide a read link on their website.

Is it safe to cover my camera with tape?

Yes. Many people cover their camera with tape or a sliding shutter for privacy. This does not harm your computer. Just make sure the tape or cover does not block any vents on your laptop, as that could cause overheating.
