What is a webcam test?
A webcam test shows you what your camera and microphone are actually delivering before a real call does: a live preview, the resolution and frame rate the browser managed to negotiate, and a level meter that moves when you speak. This page reads your devices through the browser's getUserMedia API — the same one Zoom, Teams, and Google Meet use — so if it works here, it will work there.
Can an online webcam test record you?
Any site you grant camera permission to can see the stream while its page is open, so the question is fair. On this page the stream goes from your camera to the preview and nowhere else: no frame or audio sample is part of any network request, and the optional recording lives in tab memory until you leave. You can verify that in your browser's DevTools Network tab while the test runs — the only request you'll see is the site's own tiny analytics ping, which carries a click event and never media. Two more habits worth keeping: your camera's indicator light tells you when any site is reading the stream, and you can revoke a site's permission afterwards via the icon in the address bar.
How do I test my mic and hear myself?
Use the Record button: record a few seconds, then play it back. That is deliberately not a live loopback: routing the mic straight to your speakers causes a feedback squeal, and echo cancellation would make what you hear a poor guide to how you sound to others. The recording is made with the browser's MediaRecorder API on your own machine. Check the processing flags under the meter too: echo cancellation and noise suppression are what call apps apply by default, so the recording is close to what the far end of a call hears.
How do I check my webcam's resolution and quality?
Start the test and read the stats under the preview. This page asks the camera for full HD (1920×1080), so the resolution shown is the best your camera and browser could agree on: a 720p webcam will report 1280×720. The frame rate line shows two numbers — what the camera promises and what it actually delivers, measured frame by frame. If the measured rate sags well below the promise, the usual culprit is dim lighting: the camera lengthens its exposure to compensate and gives up frames to do it.
Why is my webcam or microphone not working?
The three usual causes, in order: another app is holding the device (close Zoom, Teams, or OBS — a webcam can serve one app at a time), the browser was told no once and remembers it (click the camera icon in the address bar to re-allow), or the operating system is blocking browsers entirely. On Windows, check the camera privacy settings; on macOS, it is the Privacy & Security pane. The error messages above tell you which case you hit.
What does a site learn about your devices once you click Allow?
More than the video. After one permission grant, a site can enumerate every camera and microphone connected to your machine by exact model name — "Logitech HD Pro Webcam C920", "OBS Virtual Camera" — which is distinctive enough to help track you across sites, and is how exam proctoring software spots virtual cameras. This page shows device names only to you, in the pickers above. How that enumeration works and what it reveals is covered in our camera fingerprinting article, which includes a live test of what your browser exposes.
