Webcam test for Microsoft Teams

Teams is the most common place to meet a camera that works everywhere else and not there — usually because another app is holding it, or because Windows camera permissions are off. Test below, then use the fixes.

Best webcam under ₹3,000

Under ₹3,000, the Lenovo 300 FHD is the best all-round 1080p webcam for calls, with a wide 95° lens and two mics. The eMeet C950 costs less and keeps the frame tight on you, and the Razer Kiyo is the one to buy for a dark room because it has its own ring light.

The short answer

Microsoft Teams needs 640×360 at 30fps and caps most meetings at 1280×720. If the test below shows 720p at 30fps, your camera is ready for Teams; a black preview in Teams alone is a permission or conflict problem, not a camera fault.

How to use it

Three steps, about three seconds

  1. Step 1: Open the test

    Open the Spolvero webcam test in the browser you use for calls.

  2. Step 2: Allow the camera

    Select Test my camera and choose Allow when the browser asks for camera access.

  3. Step 3: Read the result

    Your live preview appears with a readiness score, plus resolution, frame rate and lighting checks and a fix for anything marked amber or red.

Four things worth doing before you join

  • The desktop app and the browser hold the camera separately

    If the Teams desktop app is open in the background, it can keep the camera and leave this test — or a Teams web meeting — with nothing. Quit Teams fully from the system tray before testing.

  • Check Windows camera permissions

    Settings → Privacy & security → Camera. Both 'Let apps access your camera' and 'Let desktop apps access your camera' need to be on for the Teams desktop app to see anything.

  • Teams caps at 720p

    There is no HD toggle to find. Teams limits most meetings to 720p and lowers it further on a weak connection, so a 1080p camera and a 720p camera look the same in a call.

  • Use the Teams device test too

    Teams has its own check under Settings → Devices → Make a test call. Use it to confirm Teams itself is wired up once this page has confirmed the camera works.

Troubleshooting

If the camera didn't start

Open the one that matches what the test told you — these are the steps for Teams. If the test detected the problem, that section is already open.

Teams and this page hold their own camera permissions separately, and on Windows there is a third layer sitting above both of them.

  1. 1Select the camera icon at the left of the address bar, set Camera to Allow, then reload.
  2. 2On Windows, open Settings → Privacy & security → Camera and confirm your browser is listed and switched on.
  3. 3Test in the browser you will actually join Teams from. A permission granted in Edge means nothing in Chrome, and Firefox has historically not supported Teams calling at all.
Every browser and operating system

"We can't find your camera" in Teams and "no camera found" here have the same three causes, in this order of likelihood.

  1. 1Check the lens cover and the camera kill switch first. No setting gets past hardware that has cut the camera off.
  2. 2Turn on 'Let desktop apps access your camera' in Settings → Privacy & security → Camera. This is the one the Teams desktop app needs and the browser does not, which is why a camera can work in Teams web and not the Teams app.
  3. 3Open Device Manager → Cameras. A yellow warning triangle means a driver problem — if it broke after a Windows update, right-click → Properties → Driver → Roll Back Driver.
Every browser and operating system

The Teams desktop app holds devices even when minimised, and it will happily block a Teams meeting running in the browser on the same machine.

  1. 1Quit Teams fully from the Windows system tray or the Mac menu bar, rather than closing the window.
  2. 2Open Task Manager and end any Teams processes still listed.
  3. 3Reload this page. Once it shows a picture, restart Teams — an app that was refused the camera does not retry on its own.
Every browser and operating system

Teams caps most meetings at 720p and lowers it further on a weak connection, so a dark or soft picture here is light rather than hardware.

  1. 1Put a light in front of you. Teams reduces quality further with many people on screen, so a dim starting picture gets worse in the call, not better.
  2. 2Turn off background blur and background images, which cost CPU and make the video stutter.
  3. 3Clean the lens, then use Teams' own Settings → Devices → Make a test call once the picture here looks right.

Above 1080p at 30fps there is nothing more to gain for a meeting: mainstream call apps will not send it.

Before the call

Two minutes now beats an apology later

Most people discover a camera problem in the first thirty seconds of a meeting, in front of everyone. Checking beforehand costs nothing and takes about as long as opening the meeting link.

Privacy

How this tool handles your camera

A camera test that uploads your face would defeat the point. This one cannot.

Read the site privacy policy
  • Your browser opens the camera and hands the stream to this page. The page shows it in a video element and samples it on a canvas — both are in your own tab.
  • There is no upload code, no recording and no server that could receive video. Nothing is stored in your browser either.
  • Permission is per-site and per-browser, and you can withdraw it any time from the address bar.
  • Close the tab and the camera stops. The indicator light goes out because the stream really has ended.
FAQ

Questions people ask

Anything we've missed?

Tell us

Teams says 'We can't find your camera'. What now?

Work through it in this order: run the test on this page. If the camera works here, the hardware is fine — quit Teams from the system tray, check Windows camera permissions for desktop apps, then restart Teams. If it fails here too, follow the 'No camera was found' steps below.

Why is my Teams video blurry when this test shows 1080p?

Teams caps meeting video at 720p and drops it further when bandwidth is tight. It also compresses more heavily with many people on screen.

Can I use Teams video in a browser?

Yes, in Chrome and Edge. Safari support is limited, and Firefox has historically not supported Teams calling — use the desktop app there.

My camera works in Teams web but not the Teams app.

That points straight at the 'Let desktop apps access your camera' setting in Windows privacy settings, which browsers do not need but the desktop app does.
