Your camera is probably already on — you just need to let programs use it
Most laptops have a camera built into the top of the screen. The camera itself does not have an on/off switch. Instead, your operating system controls whether programs can access it. If your camera is not working, the problem is usually one of three things: the camera is disabled in your system settings, a program does not have permission to use it, or the camera driver (the software that runs the hardware) needs updating.
The steps below cover Windows and Mac separately, because the menus are different on each. Start with whichever system you use. If you get stuck at any step, the troubleshooting section at the end covers the most common reasons a camera stays dark.
Key Takeaways
- Your laptop camera is controlled through system settings, not a physical switch, and you may need to turn it on separately for each program that uses it.
- On Windows, check Settings > Privacy & Security > Camera to see which programs can access your camera and turn them on individually.
- On Mac, go to System Settings > Privacy & Security > Camera to manage which apps have permission to use the camera.
- If your camera still does not work after checking permissions, restart your laptop — this fixes the problem about half the time.
- Some laptops have a physical camera cover or a keyboard shortcut that disables the camera; check your laptop's manual or function keys if settings show the camera is on but it still will not work.
Enabling your camera on Windows
Open Settings by pressing the Windows key and typing "Settings", then press Enter. Click on "Privacy & Security" in the left menu. Scroll down and click "Camera".
At the top of the Camera page, you will see a toggle that says "Camera access". If it is off (the switch will be gray and to the left), click it to turn it on. The switch will turn blue and move to the right. This turns on camera access for your whole system.
Below that toggle, you will see a list of programs. Each one has its own toggle. Find the program you want to use the camera with — for example, Zoom, Teams, or your web browser — and make sure its toggle is on. If a program is not listed, it means it has never asked for camera permission. Once you open that program and it asks for permission, it will appear here.
Close Settings and open the program you want to use. It should now be able to access your camera. If it still does not work, move to the troubleshooting section below.
Enabling your camera on Mac
Click the Apple menu in the top-left corner and select "System Settings". Click "Privacy & Security" in the sidebar. Scroll down and click "Camera".
You will see a list of programs that have asked for camera permission. Each one has a checkbox. If the program you want to use is listed and its checkbox is unchecked, click the checkbox to turn it on. If the program is not listed, it means it has not asked for permission yet.
Close System Settings and open the program you want to use. When it asks for permission to use the camera, click "Allow". The program will then appear in the Camera list in System Settings, and you will be able to use it.
If a program keeps asking for permission every time you open it, go back to System Settings > Privacy & Security > Camera and make sure the checkbox next to that program is checked.
What to do if your camera is still not working
Restart your laptop. This sounds straightforward, but it fixes camera problems about half the time because it resets the connection between your operating system and the camera hardware. Save your work, then shut down completely and turn the laptop back on. Wait for it to fully load before opening your program again.
Check for a physical camera cover or switch. Some laptops have a sliding cover over the camera lens, or a keyboard shortcut that disables it. Look at the top of your screen around the camera — you may see a small slider. If your function keys have a camera icon with a slash through it, try pressing that key (usually Fn + the camera key) to toggle the camera back on.
Update your camera driver. On Windows, right-click the Start button and select "Device Manager". Look for "Cameras" in the list and click the arrow next to it. Right-click your camera and select "Update driver". Choose "Search automatically for updated driver software". On Mac, go to Apple menu > System Settings > General > Software Update and install any updates available.
Testing your camera before an important call
Before you join a video meeting, open the program you will be using and look for a settings or preferences menu. Most programs have a camera preview where you can see what your camera is showing before you join. This tells you when ready whether the camera is working and whether you like what it is showing.
If the preview is black or blank, the camera is not working yet. Go back to the system settings steps above and check that the program has permission. If it does and the preview is still blank, restart your laptop and try again.
If the preview shows your face but it is upside down or sideways, that is usually a driver issue on Windows. Go to Device Manager, right-click your camera, select "Properties", and look for a "Rotation" or "Orientation" setting. Change it to the correct direction.
Why programs ask for camera permission separately
Each program asks for permission because your operating system treats the camera as a shared resource. Only one program can use the camera at a time, and the system wants to make sure you know which programs can access it. This is a privacy feature — it prevents a program from secretly turning on your camera without your knowledge.
When you give a program permission, that permission stays in place. You do not have to approve it again the next time you open the program. If you change your mind and want to revoke permission, go back to Camera settings and turn off the toggle for that program.
Frequently Asked Questions
Can I use my camera in two programs at the same time?
No. Only one program can access the camera at a time. If you try to open a second program that uses the camera, it will either show a black screen or tell you the camera is in use. Close the first program or stop using the camera in it, then the second program can access it.
My camera works in one program but not another. What is wrong?
The program that is not working probably does not have permission. Go to your camera settings (Settings > Privacy & Security > Camera on Windows, or System Settings > Privacy & Security > Camera on Mac) and make sure the toggle for that program is on. If the program is not listed, open it and look for a permission prompt.
I see my camera in Device Manager but it says there is a problem with it.
Right-click the camera in Device Manager and select "Uninstall device". Restart your laptop. Windows will automatically reinstall the camera driver when it boots back up. If the problem persists, visit your laptop manufacturer's support website and read the latest camera driver for your model.
Is it safe to cover my camera with tape?
Yes. Many people cover their camera with tape or a sliding cover for privacy. This does not hurt the camera. Just make sure whatever you use does not leave sticky residue on your screen, and remove it gently so you do not scratch the lens.
My laptop is very old. Does it have a built-in camera?
Laptops made before 2010 often do not have built-in cameras. If you cannot find a small lens at the top of your screen, your laptop probably does not have one. You can buy an external USB camera for about twenty to fifty dollars and plug it into any USB port on your laptop.
