Teams Camera Not Working? One Toggle Says Allow

You can see everybody else and they are looking at a black rectangle where you should be. Your camera is almost certainly fine.

Windows keeps a permission for cameras twice over, once for everything and once for each application, and the two do not have to agree. That is where this usually sits.

I counted what this machine had set first, and found the master switch saying allow while two applications sat denied.

Ours: allowed at the top, denied underneath

The measurement, and it is the whole mechanism.

Ours, and read on the PC used to write this. The global camera permission read Allow. Underneath it were 7 application entries, of which 4 were allowed and 2 were denied.

⛔ A denied application sees no camera at all. The main switch being on changes nothing. Not for that app.

⚡ Look at yours the same way. It only reads:

Get-ItemProperty "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\CapabilityAccessManager\ConsentStore\webcam"

⭐ This machine has exactly one camera and I found it reporting healthy. Hardware is rarely the problem when other applications work.

Microsoft's route to the per-app switch

The documented fix, quoted.

Documented by Microsoft on its Teams camera page: "Open the Settings app on your device. Select Privacy & security > Camera."

Then the switch that matters: "Under Let apps access your camera, turn the Microsoft Teams (work or school) toggle on".

⭐ And the part people skip: "If the toggle is already turned on, turn it off and back on again."

⚡ That is not superstition. Toggling rewrites the permission. It clears a stale state that reads as on and behaves as off.

Test it inside Teams first

Thirty seconds, and it saves a lot of guessing.

Microsoft's own route: "At the top-right of Teams, select Settings > Devices. Under Audio settings, select Make a test call."

⭐ The test call shows your camera as well as your microphone. If you see yourself there, Teams and Windows are both fine and the meeting itself is the problem.

⚠️ Teams keeps its own device choice, exactly as it does for sound. The microphone version of this is the same trap.

Virtual cameras, which nobody remembers installing

The cause that produces the strangest symptoms.

⛔ A virtual camera can sit in the list looking real. Streaming software, filters and phone-as-webcam apps all install them.

⚡ They stay in the list after the app is closed, and Teams may still be pointed at one.

⭐ Pick your physical camera by name in the device list, not whatever is selected.

⚠️ A frozen image or somebody else's background rather than a black square is nearly always a virtual camera still running.

In a browser it is a third layer

Because Teams on the web asks separately.

⭐ The site itself needs camera permission, on top of Windows and on top of the per-app setting.

⚡ Microsoft lists the supported browsers: "Chrome, Safari, Edge, Firefox, and Internet Explorer 11."

⚠️ A padlock or camera icon in the address bar shows what the site is allowed. Fastest place to check.

When it is Windows rather than Teams

How to tell in one step.

⭐ Open the Camera app that comes with Windows. If you see yourself there, Windows and the hardware are fine.

⛔ A black picture in the Camera app too moves this off Teams entirely. The full list for a camera that will not work anywhere is longer.

⚠️ And a laptop with a physical shutter catches people out weekly. Check the slider above your screen. Before anything else.

⚡ Ours, and marked as ours: I would test in the Camera app first. Ten seconds, and it decides which of two investigations you are in.

The order worth working through

Five checks, quickest first.

⭐ Physical shutter, then the Camera app. Both free.

⭐ Then the per-app permission, toggled off and on.

⚡ Then pick the camera by name in Teams, avoiding anything virtual.

⚠️ Then close every other app that could hold the camera. Only one application gets it at a time on many machines.

⛔ Then restart Teams properly, from the taskbar tray rather than the window, because closing the window leaves it running.

Status: read against Microsoft's Teams camera documentation, 25 August 2026, on Windows 11. Microsoft supplies the Settings, Privacy and security, Camera route, the per-app toggle, the instruction to turn it off and back on, the test call route and the list of supported browsers. The camera count and the permission entries were read on this PC.

Why does Teams show a black screen instead of my camera?

Most often the per-app camera permission is off for Teams even though the main camera switch is on. Windows keeps both, and they do not have to agree. On the PC here the global setting said allow while two applications were denied.

Where is the camera permission for Teams in Windows?

Settings, then Privacy and security, then Camera. Under Let apps access your camera, find Microsoft Teams. Microsoft also says that if the toggle is already on, turn it off and back on again.

My camera works in the Camera app but not in Teams. Why?

Because the per-app permission or the device choice inside Teams is wrong, not the hardware. That split is the useful test: working in the Camera app rules out the camera and the driver in one step.

What is a virtual camera and why is it selected?

It is a software camera installed by streaming, filter or phone-as-webcam apps. It stays in the device list after the app closes, and Teams may still be pointed at it. Pick your physical camera by name instead.

The Short Version

• Windows keeps a global camera permission and a separate one per application.
• On this PC the global switch said allow while two applications were denied.
• Settings, Privacy and security, Camera holds both.
• Microsoft says to turn the app toggle off and back on even if it looks on.
• Make a test call in Teams shows your camera as well as your microphone.
• A virtual camera left behind by another app explains the strangest symptoms.
• Test in the Windows Camera app to rule the hardware in or out in ten seconds.
• Check for a physical shutter above the screen before any of this.

Where to Next

Open the Windows Camera app first. Seeing yourself there rules out the camera, the cable and the driver in one go.

Then open Settings, Privacy and security, Camera and toggle the Teams permission off and back on.

Then pick your camera by name in Teams settings, avoiding anything that is not the physical one.

Anyone who found a virtual camera selected that they had forgotten installing, name the app in the comments. Those cause a lot of these.
