如何测试您的网络摄像头？

在在线会议或直播之前测试您的网络摄像头至关重要。单击“启动相机”按钮并授予浏览器权限。如果您在屏幕上看到自己，则表明您的相机工作正常。我们的工具还可以实时分析您相机的最大分辨率和帧速率 (FPS)。

为什么我的相机不工作？

如果屏幕仍然黑屏，请检查您的网络摄像头是否有关闭的物理隐私快门。另外，请确保当前没有其他应用程序（例如 Zoom 或 Skype）正在使用该摄像头，因为大多数网络摄像头一次只能由一个程序使用。

Before joining an important video conference, live stream, or online class, it is crucial to ensure your camera is working correctly. Our Free Online Webcam Test provides a fast, secure, and intuitive way to check your camera's functionality, resolution, and framerate without installing any heavy software.

How to use the Camera Tester

  1. Click the "Test Camera" button on the interactive panel above.
  2. When prompted by your browser, select "Allow" to grant camera access. (We respect your privacy; your video feed never leaves your device).
  3. Look at the video preview on your screen. If you can see yourself clearly, your camera is fully operational.

Common Webcam Problems & Solutions

If the video feed is black or you receive an error, try these troubleshooting steps:

  • Another app is using the camera: Webcams can only be used by one application at a time. Close Zoom, Skype, OBS, or any other program that might be holding the camera hostage.
  • Physical Privacy Shutter: Many modern laptops (like Lenovo or HP) have a physical sliding shutter over the lens. Ensure it is open!
  • Browser Permissions: Ensure you haven't blocked camera access in your browser settings. Click the lock icon next to the URL to verify.
  • Outdated Drivers: If you are using an external USB webcam (like Logitech), ensure you have downloaded the latest drivers from the manufacturer's website.

Your privacy is our top priority. This webcam test is built using the standard WebRTC API. The video stream is processed entirely within your browser on your local machine. No video data is ever recorded, streamed, or uploaded to our servers.
