Is your webcam not working properly or producing poor video quality? Built on the browser's MediaDevices API, this tool captures real-time video streams from your device's camera to test key parameters like resolution, frame rate, and color performance. It outputs real-time video and performance data to help you quickly evaluate your webcam's status.
Q: Why does the webcam test show a black screen?
A: First, check your browser permission settings to ensure camera access is allowed. Second, confirm that the webcam is not being used by another application.
Q: How can I test the frame rate stability of my webcam?
A: In a well-lit environment, observe the motion blur of moving objects in the video feed. The FPS value displayed by the tool should remain stable. Normal video calls require at least 30 FPS.
Please close other applications using the webcam before testing. Be mindful of covering your webcam in privacy-sensitive environments. Some browsers may restrict HTTP sites from accessing the camera. For external webcams, ensure the drivers are properly installed first.
We recommend testing 30 FPS frame rate stability at 1080p resolution, as this is the basic requirement for video conferencing. In a typical test scenario (a well-lit indoor environment where a face occupies 1/3 of the frame), facial details should be clearly visible with accurate color reproduction. If the frame rate fluctuates by more than ±5 FPS, it may indicate a device performance or driver issue.
