About Webcam Test
A webcam test confirms that a camera is connected, allowed, and producing a picture. After you grant camera permission, the page shows a live preview and reports the device name, the resolution in pixels, and the frame rate when the browser provides it. The video stays inside this page: it is not recorded, stored, or sent to a server. The test uses the default camera and needs a secure (HTTPS) connection.
Questions about Webcam Test
Why does the test say permission denied?
The browser or the operating system blocked camera access. Click the padlock or camera icon in the address bar and allow the camera for this site, then check the privacy settings of your system, which can block cameras for all browsers.
Why is the preview black even though the camera is on?
Common causes are a closed privacy shutter, a lens cover, or another program such as a video call app already using the camera. Close other apps that might hold the camera, then turn the test off and on again.
