What does a webcam test check?
It asks for camera permission and displays a live, muted preview so you can confirm that a camera stream reaches the browser.
The preview stays in the page; stop the test when finished to turn off the camera tracks.

Browser Camera Access and Privacy
A webcam test checks whether the browser can request access to a camera and render its live stream in a page. Browsers require explicit permission, and camera access generally needs HTTPS or localhost. The browser's site permission, operating-system privacy controls, another app using the camera, or a disconnected device can affect whether a preview appears. A local preview is useful before a video call or online class, but it does not guarantee that another meeting app selected the same camera or that the image quality is suitable. This page displays a muted preview without taking a still photo or uploading video. Stop the test when you finish to release the camera, and review the browser's camera indicator if you are unsure whether access is still active.

Common Mistakes
Denying permission and expecting the preview to appear
The page cannot receive a camera stream until access is allowed in both the browser and, where applicable, system privacy settings.
Assuming a successful preview means every video app is configured
Each app can use a different camera selection, permission state, framing, or network setup.

Frequently Asked Questions
Does this tool capture a picture?
No. It shows a live muted preview only and does not create an image or upload video.
Why is camera access unavailable?
Camera access requires browser permission, a supported device, and usually HTTPS or localhost. System privacy settings can also block it.
Can another app use the camera at the same time?
Some devices or operating systems limit simultaneous camera access. Close other video apps and try starting the preview again.
Does the preview guarantee my meeting app is ready?
No. It confirms this page can display a camera stream; choose and test the camera separately in the meeting app you plan to use.
