Find and open your camera app
Your PC camera is almost certainly already on at the hardware level — the switch is in software. On Windows, search for "Camera" in the taskbar search box and click the Camera app when it appears. On a Mac, open Finder, go to Applications, then Utilities, and double-click Facetime or Photo Booth (both use your built-in camera).
If you don't see a Camera app on Windows, your PC may not have one pre-installed. In that case, you can read the Camera app free from the Microsoft Store. Open the Microsoft Store, search "Camera", and click Install on the official Microsoft Camera app.
Once the app opens, you should see a live feed from your camera. If you see a black screen or a message saying the camera is not found, move to the troubleshooting section below.
Key Takeaways
- Windows PCs use the Camera app (search for it in the taskbar), and Macs use Facetime or Photo Booth, both in Applications > Utilities.
- If your camera shows a black screen, check that no other app is using it and that your camera is not disabled in Device Manager (Windows) or System Settings (Mac).
- Built-in laptop cameras are usually located above the screen; external USB cameras plug into any USB port and may need a driver installed.
- If Device Manager shows a yellow warning triangle next to your camera, right-click it and select Update Driver to fix the problem.
- Some PCs have a physical camera privacy switch or a keyboard shortcut (often Fn + a key with a camera icon) that disables the camera entirely.
Check if another app is already using the camera
If the Camera app opens but shows a black screen, another program may have locked the camera. Close any video conferencing apps (Zoom, Teams, Google Meet, Skype) that might be running in the background. Check your taskbar for any app icons you recognize as video or communication tools, right-click them, and close them.
On Windows, you can also open Task Manager (press Ctrl + Shift + Esc), look for any apps with names like Zoom, Teams, or Skype, click them, and click End Task. Then try opening the Camera app again.
Verify the camera is not disabled in settings
On Windows: Open Device Manager by right-clicking the Start button and selecting Device Manager. Look for "Cameras" in the list and click the arrow next to it to expand. If you see your camera listed with a yellow warning triangle or a down arrow, the camera is disabled. Right-click it and select Enable Device. If there is no yellow triangle, your camera is already enabled.
You should also check privacy settings. Open Settings (press Windows key + I), go to Privacy & Security, then Camera. Make sure the toggle next to "Camera access" is turned on. Below that, check that the Camera app itself has permission — it should show a toggle next to "Camera" in the list of apps.
On Mac: Open System Settings, click Privacy & Security, then Camera. You will see a list of apps that have requested camera permission. Make sure Facetime or Photo Booth (whichever you want to use) is checked. If it is not listed, the app has never requested permission — open the app again and it should prompt you to allow access.
Look for a physical camera switch or keyboard shortcut
Some laptops have a physical privacy switch or shutter that covers the camera. Check above your screen for a small slider or lever. If you find one, make sure it is in the open position.
Many PCs also have a keyboard shortcut to disable the camera. Look at your keyboard for a key with a camera icon, often near the function keys (F1 through F12). It may say Fn + that key. Press the combination once to toggle the camera on. The shortcut varies by manufacturer — common ones are Fn + V (Lenovo), Fn + F10 (HP), or Fn + Camera icon (Dell).
Update or reinstall the camera driver
If Device Manager shows your camera with a yellow warning triangle, the driver (the software that lets Windows talk to the camera) needs updating. Right-click the camera in Device Manager and select Update Driver. Choose "Search automatically for updated driver software" and let Windows search and install any available update.
If that does not work, right-click the camera again and select Uninstall Device. Then restart your PC. Windows will automatically reinstall the driver when it boots back up. Once it finishes, open the Camera app again.
On a Mac, drivers are built into the operating system and update automatically, so you do not need to do this step. If your Mac camera is not working, restart your Mac first — that solves most camera problems on macOS.
Check if you are using an external USB camera
If your PC is a desktop or if you are using an external camera plugged into a USB port, make sure the cable is fully inserted and the port is working. Try plugging the camera into a different USB port on your PC.
Some external cameras come with a driver disc or require you to install software before they work. Check the box or the manufacturer's website for any setup instructions. Plug the camera in, then install the software if needed, then open the Camera app.
If the camera still does not appear in Device Manager, the USB port itself may be broken. Try the camera on another PC to confirm it works, or try a different USB device (like a flash drive) in the same port to see if the port is the problem.
Restart your PC as a final step
If you have tried the steps above and the camera still will not turn on, restart your PC. Many camera problems are temporary and clear themselves after a reboot. Save any open work, then restart.
After the restart, open the Camera app again. If it still does not work, the camera hardware itself may be faulty. Contact your PC manufacturer's support line — they can walk you through more advanced troubleshooting or arrange a repair if the camera is defective.
Frequently Asked Questions
Why is my camera showing a black screen even though it is enabled?
Another app is likely using the camera. Close Zoom, Teams, Skype, or any video conferencing software running in the background. If that does not work, restart your PC — sometimes a camera gets stuck and a reboot frees it up.
How do I know if my PC has a built-in camera?
On a laptop, look above the screen for a small lens. On a desktop, you will not have a built-in camera — you will need to plug in an external USB camera. You can also check Device Manager (Windows) or System Settings (Mac) to see if a camera is listed.
Can I use my phone as a PC camera?
Yes, but you need third-party software. Apps like Iriun Webcam or DroidCam let you connect your phone to your PC via USB or Wi-Fi and use it as a webcam. read the app on both your phone and PC, then follow the app's instructions to connect them.
What if the Camera app is not installed on my Windows PC?
Open the Microsoft Store, search for "Camera", and click Install on the official Microsoft Camera app. It is free and takes a few minutes to read. Once installed, search for Camera in your taskbar and open it.
Is my camera always recording, even when I am not using it?
No. Your camera only records when an app is actively using it. You can see which apps have camera permission in Settings > Privacy & Security > Camera (Windows) or System Settings > Privacy & Security > Camera (Mac). You can turn off permission for any app you do not trust.
