Webcam Test
Check that your webcam works before a video call or online exam. Start the camera to see a live preview, then read the resolution and frame rate it is actually delivering, the camera’s name, and a list of every camera and microphone your browser can see. Try different resolutions to find out what the camera supports.

Frequently Asked Questions
Why is my webcam not detected?
Check the camera is connected and not used by another app (Zoom, Teams, the Camera app). On Windows and macOS also check the privacy settings that allow browsers to use the camera.
Why is the frame rate low?
Many webcams drop to 15 fps or less in low light. Add light, or close other apps using the camera, and test again.
Is the video recorded?
No. The preview is displayed locally and nothing is stored or sent.
Why does my image look mirrored?
The preview is mirrored by default because that feels natural. Untick “Mirror the preview” to see what other people see.
