How to test a camera before a remote proctored exam

Your webcam may look fine in a video call but behave differently in the browser your exam uses. A dark image, blocked permission, or the wrong camera can hold up check-in or make it hard for the proctor to see you.

Test the camera before exam day, then check it again in the exam provider's own system test if one is available. The Camera Test shows a live preview, resolution, and frame rate so you can catch basic camera problems in your browser.

Test your camera before the exam

Use the computer and browser you plan to use for the exam. Set up in the room where you expect to take it, and connect the webcam if it is external.
Open the Camera Test. When your browser asks to use the camera, allow access. If no prompt appears, check the camera permission for the site in your browser.
Look at the live preview. Check that your face is visible, the image is not black or frozen, and the camera is aimed at the position where you will sit.
Move your head and hands gently while watching the preview. Check whether the image updates smoothly, and note the resolution and frame rate shown by the test.
Make any changes to your setup, then use the exam provider's practice check or system test too. The browser test checks camera access, but it cannot confirm that the exam software accepts your device or setup.

Follow the exam provider's rules for camera placement, room view, and permitted devices. Some exams require a specific browser, a clear view of your face, or a room scan. Do not assume a phone or external camera is allowed unless the provider says so.

What the camera test results mean

The preview is clear and moves smoothly

Your browser can access the camera and display an image. This is a good basic result, but it does not prove that the proctoring platform will use the same camera, grant permission, or accept the image quality. Check the exam platform separately before the exam.

The image is dark, blurry, or grainy

The camera is working, but the picture may be difficult to review. Low room lighting, a dirty lens, a camera aimed at a bright window, or a low-quality webcam can cause this. Improve the light and position before deciding that the camera is faulty.

The preview is black or does not appear

The browser may not have camera permission, another app may be using the camera, or the operating system may be blocking access. Check the fixes below. If the camera is missing from the computer's camera settings too, check its connection or device status.

The preview freezes or updates unevenly

The camera may be busy, the browser may be struggling, or a connection or driver problem may be interrupting the preview. Close other apps that use video and repeat the test. A smooth browser preview still does not guarantee that a separate proctoring app will perform the same way.

How to fix camera problems

Open the lens cover and check the cable. Remove any webcam privacy cover, confirm that the camera is not physically switched off, and reconnect a USB camera. Try another USB port if the preview remains blank.
Allow camera access in the browser. Select the site controls icon beside the address bar and set camera access to allow, then reload the page. Browser labels vary, so look for the camera permission for the current site.
Allow camera access in the operating system. On Windows 11, open Settings › Privacy & security › Camera. Turn on Camera access and Let desktop apps access your camera. On a Mac, open System Settings › Privacy & Security › Camera and allow your browser. Reopen the browser if it was already running when you changed the permission.
Close other camera apps. Quit video meeting apps, camera utilities, and other browser tabs that might be using the webcam, then reload the test. If a camera works only after another app closes, leave that app closed during the exam.
Choose the camera the exam will use. If your computer has a built-in camera and an external one, disconnect the camera you do not plan to use, or choose the intended device in the exam platform's camera settings. Repeat its system test after changing the selection.
Improve the view. Wipe the lens with a soft cloth. Face a light source rather than placing a bright window behind you, and put the camera near eye level. Sit at the distance and angle required by the exam instructions.
Restart the computer and test again. This can release a camera held by a stuck app and reload a camera driver. If a work or school computer still blocks access, contact its administrator rather than changing managed settings.

If the exam provider allows a phone, check camera permission there as well. On iPhone, look under Settings › Privacy & Security › Camera. On Android, look under Settings › Security & privacy › Privacy › Permission manager › Camera, though menu names vary by device and Android version.

Check your framing and lighting

A camera can pass a technical test while still giving the proctor a poor view. Sit where you will take the exam and check that your face is in the frame, your eyes are not hidden in shadow, and the camera stays steady. If the instructions require a view of your desk or room, arrange the camera as directed instead of relying on a standard face-level position.

Keep the computer plugged in if practical, disable automatic sleep for the exam period if the provider permits it, and avoid changing camera or browser settings after the final check. A browser preview is a useful first check, not a guarantee that the remote exam will approve your setup.
