How this Webcam Test works
This tool accesses your camera through the browser's MediaDevices API, which is a standard web interface that does not require any third-party software or browser extensions. When you click Start Camera, the tool calls getUserMedia with an ideal resolution of 1280×720 and your chosen device ID. The browser then asks for camera permission and, once granted, passes a MediaStream object directly to a video element on the page. The video plays in real time entirely in your browser tab. After the stream starts, the tool reads the active video track's settings — width, height, and frame rate — using the getSettings method, and displays them in the info grid below the preview. If more than one camera is available, the tool calls enumerateDevices to list all videoinput sources and populates the device selector. Choosing a different device restarts the stream with the new device ID. Mirror mode applies a CSS scaleX(−1) transform to the video element, matching the natural front-camera view most users expect. The snapshot feature draws the current video frame to an off-screen canvas element and exports it as a PNG data URL, which you can then download. No video data is sent to any server at any point; everything runs locally inside your browser.
