Camera check before a telehealth call

A telehealth appointment is about to start, but you are not sure whether the camera is working, whether the picture is too dark, or whether the other person will see the right view. A quick check can catch these problems before you join.

Use the Camera Test to view your camera in a browser and check the available resolution and frame rate. Then adjust your setup and confirm that the browser and video-call app can access the camera.

Check your camera before the call

1. Open the Camera Test in the browser you plan to use. Allow camera access when the browser asks for permission.
2. Look at the live preview. Check that your face is visible, the camera points in the right direction, and the image is not blocked by a shutter, case, or object.
3. Sit in your usual position and move naturally. Check whether the image stays clear as you turn your head or reach for something nearby.
4. Review the reported resolution and frame rate. These show what the browser receives from the camera during this check.
5. Close the test before opening your telehealth app or meeting link. Then check the camera selection and preview inside the call app, if it offers one.

Set up the camera where you will take the call. A test from another room or with different lighting may not match what the person on the call sees.

What the camera check tells you

The preview is clear and shows the right view

The camera and browser can provide a live image. This does not guarantee that the telehealth app will use the same camera, so check the app's camera selection before the appointment starts.

The picture is too dark or your face is hard to see

The camera is working, but the lighting or angle needs attention. Move a light source in front of you, or face a window. A bright window behind you can make your face look dark because the camera adjusts to the brighter background.

The picture looks soft or choppy

Check that the lens is clean and that you have enough light. A camera may lower its frame rate in dim conditions. The call app may also reduce video quality when the connection is slow, so a good result in this test does not promise the same quality during a call.

The preview is blank or no camera is available

The browser may not have permission, another app may be using the camera, or the device may not recognize it. Work through the fixes below, then reload the test page.

How to fix camera problems

1. Open the shutter and clear the lens. Check for a physical privacy cover, a camera switch, or a lens blocked by a case. Wipe the lens gently with a clean, soft cloth.
2. Improve the lighting and camera position. Face a window or place a lamp in front of you, not behind you. Set the camera near eye level and frame your head and shoulders so you do not need to lean toward the screen.
3. Allow camera access in the browser. Use the camera or site-permission control beside the address bar to allow camera access for the page, then reload it. If you previously blocked access, change the saved permission before trying again.
4. Check system camera permissions. In Windows 11, open Settings › Privacy & security › Camera and turn on camera access, including access for desktop apps if your call app needs it. On macOS, open System Settings › Privacy & Security › Camera and allow access for your browser or call app.
5. Check camera permission on your phone or tablet. On Android, open Settings › Apps › your browser or call app › Permissions › Camera and allow access. On iPhone, open Settings › Privacy & Security › Camera and allow the app. Menu names can vary by device and software version.
6. Close other camera apps. Quit other meeting apps, camera previews, and recording apps, then try again. After the test, close its camera preview before opening the call app, especially if the app reports that the camera is already in use.

When the camera may be faulty

If the camera still has no image after you check permissions and close other apps, restart the device and test again. For an external webcam, reconnect its cable and try another USB port. If it fails on more than one computer or phone, the camera or cable may need repair or replacement. If a built-in camera is not detected after these checks, contact the device maker or a repair shop.

Why the call can look different from the test

The Camera Test checks the browser's live camera feed, not the full telehealth service. The call app may choose a different camera, crop the picture, apply its own image processing, or lower video quality to keep the call going. Check the preview in the actual call app when possible, and follow the clinic's instructions if it provides a connection or equipment check.

The Camera Test runs in your browser. It shows a live preview and does not create a recording.
