What Is a Webcam Tester?
Before a video call goes wrong is the time to find out the camera works. This tester asks for camera permission, streams the feed into a local <video> element and reads the resolution and frame rate from the track's settings via MediaStreamTrack.getSettings(). No frames are uploaded, copied or analysed — when you click Stop or close the tab, the stream ends.
Remote workers verify a new laptop's camera before joining a customer call. Streamers check that the right capture device is selected after a USB-hub change. IT teams use it as a quick diagnostic before raising hardware tickets. If the preview is black, the browser usually shows the reason in the permission prompt: another app holds the camera, OS-level permission is denied, or a privacy setting is blocking the device label.
You'll need to grant the camera permission your browser prompts for. Switching browsers (or quitting Zoom, Slack or Teams) resolves the vast majority of cases.
