Camera Test

This free online Camera Test helps you quickly check if your webcam or other cameras are working correctly. It finds every camera your browser can see and shows all of their live feeds at once, so you can verify each one before an important video call, online meeting, or streaming session.

Camera Test

How to use the camera test

  • Allow access: Click 'Allow' when your browser asks for camera permission. If you accidentally denied it, click the camera icon in your browser's address bar to change the setting, then click 'Allow camera access' in the test.
  • Check every feed: Each camera gets its own tile, labelled with the camera's name and the resolution it is currently sending.
  • Enable all: With 'Enable all' switched on, every camera runs at once. Switch it off to list your cameras without starting them, then click a camera to start just that one. Click its label again to stop it. This is handy when you have several cameras or a slow USB hub.
  • Fullscreen: Use the button in the corner of any feed to view it fullscreen and inspect the picture closely.
  • Plug and play: Cameras you connect or disconnect while the page is open are picked up automatically within a few seconds, so you usually don't need to refresh.

What the resolution label means

The size shown on each feed (for example 1920x1080) is the resolution the camera is sending to your browser right now. The test asks every camera for Full HD, but the camera and your system can settle on a lower mode, so this isn't always the highest resolution your camera supports.

If a camera reports less than you expected, check the troubleshooting tips below. A busy USB hub, an older USB port, or another app using the camera are the usual reasons.

Diagnosing camera problems

If you're troubleshooting a device for someone else, these are the patterns to look for:

  • No camera detected: The browser can't see any camera. This can be a driver issue, a hardware fault, or the camera being disabled in the operating system's privacy settings or in the BIOS/UEFI.
  • Black or frozen image: The camera is detected but not delivering video. Look for a driver conflict, a closed privacy shutter, a faulty camera module, or a loose connection to the motherboard.
  • Poor image quality: Distorted colors, flickering, or heavy noise on a feed can point to a failing sensor, a loose connection, or driver incompatibility. Compare against what that camera model should look like.
  • One camera missing: If you expect several cameras and one doesn't appear, that specific camera or its connection is the likely problem. On phones and tablets, browsers often only offer the front and rear camera, even when the device has more.
  • Working device: Clear, stable video appears promptly from every connected camera.
  • Malfunctioning device: No video, error messages such as 'Camera permission denied', black feeds, distorted or flickering video, or expected cameras not appearing.

Common Camera Issues & How to Fix Them

No camera detected or black screen

  • Permissions: Make sure you've allowed camera access for this site. If you don't see a prompt, check the camera icon in the address bar or your browser's site settings.
  • Operating system privacy: Your OS can block the camera before the browser sees it. On Windows, go to Settings → Privacy & security → Camera. On macOS, go to System Settings → Privacy & Security → Camera, and make sure your browser is allowed.
  • Other apps: Make sure no other application (Zoom, Teams, Skype, Discord, OBS) is using the camera. Close them and try again. A camera that's busy shows 'stream unavailable' in its label.
  • Connections (external cameras): Check the USB cable and try a different USB port, ideally one directly on the computer rather than a hub.
  • Drivers: Your camera drivers might be outdated or corrupted. Download the latest drivers from your computer or camera manufacturer's website.
  • Hardware switch or cover: Many laptops have a physical shutter, switch, or function key that disables the webcam. Make sure it's open or enabled.
  • Refresh or restart: Try refreshing the page. If the issue persists, restart your browser or computer.

Frozen or lagging video

  • Resources: Close other applications that are using a lot of CPU or memory.
  • USB bandwidth: Several cameras on one hub or USB 2.0 port can run out of bandwidth. Switch off 'Enable all' and start the cameras one at a time, or move a camera to another port.
  • Drivers: Outdated drivers can also cause stuttering and freezes.

Poor image quality (blurry, grainy, or wrong colors)

  • Lens: Clean the camera lens gently with a soft, dry cloth.
  • Lighting: Make sure the room is well lit. Most webcams get grainy in dim light.
  • Software settings: Some camera software lets you adjust focus, brightness, contrast, and white balance. Check those settings.
  • Camera age and quality: Older or lower-quality cameras may simply have these limitations.

Resolution is lower than expected

  • Active mode: The label shows what the camera is sending right now, not its maximum. The test requests Full HD; the camera can choose a lower mode.
  • Other apps: Close other apps using the camera, then reload the page.
  • Port and cable: Connect the camera directly to a USB 3 port. Hubs, adapters, and long cables can force a lower mode.

Use this test to identify if the issue is with the camera hardware, drivers, or software settings, helping you get back to clear video quickly.

Frequently asked questions

Why is the camera test not showing a picture?

Check that you allowed camera permission, that the camera is connected and not covered, and that no other app is using it. Then reload the page. Camera access also needs a secure (HTTPS) connection.

Does the camera test upload or save my video?

No, not at all. The feed is only displayed in your browser and is never uploaded or recorded. Feel free to inspect the network traffic with your browser's developer tools.

Can I test more than one camera at the same time?

Yes. Every camera your browser can see is shown side by side. Switch off 'Enable all' if you'd rather start them one at a time.

Why does my phone only show two cameras?

Most mobile browsers only expose the front and rear camera to websites, even if the phone has extra lenses.
