Summary: Camera works in the Windows Camera app but not in Teams or Zoom? Fix app permissions, the device already in use error, virtual camera conflicts, and driver problems.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
When the camera works in the Windows **Camera** app but fails in Teams or Zoom, the hardware and driver are fine. What is failing is one of three things: the app does not have **camera permission**, another program is **already holding the camera**, or the app is pointed at the wrong device — often a virtual camera left behind by OBS, Snap Camera, or NVIDIA Broadcast.

Windows only lets one application own a camera stream at a time on most webcams. That single fact explains the majority of "device is already in use" errors.

> **Camera not working anywhere, including the Camera app?** That is a driver or hardware problem — start with [fix a webcam not working](https://www.mytechnician.tech/tips/fix-webcam-not-working-windows-11/). **Microphone failing too?** See [fix a microphone not working](https://www.mytechnician.tech/tips/fix-microphone-not-working-windows-11/).

## Symptoms
* Black screen or **"We can't find your camera"** in Teams while the Camera app works.
* Zoom shows **"Camera is being used by another application"** or **error code 3113**.
* The camera light comes on but the preview stays blank.
* The camera works in the desktop app but not the web version, or the reverse.
* Video worked yesterday and stopped after a Windows or app update.

## Step 1: Confirm the Camera Works at All
Establish a baseline before changing anything.

1. Open the **Camera** app from the Start menu.
2. If you see yourself, the hardware and driver are fine — skip to Step 2.
3. If the Camera app also fails, stop here and work through [fix a webcam not working](https://www.mytechnician.tech/tips/fix-webcam-not-working-windows-11/) first.
4. **Close the Camera app completely** afterwards. Leaving it open is itself a cause of "camera in use" in Teams.

## Step 2: Grant Camera Permission at Both Levels
Windows 11 has two separate gates, and both must be open.

1. Open **Settings** → **Privacy & security** → **Camera**.
2. Turn on **Camera access** at the top — this is the system-wide switch.
3. Turn on **Let apps access your camera**.
4. Scroll down and turn on the specific app: **Microsoft Teams**, **Zoom**, or your browser.
5. Crucially, scroll to the bottom and turn on **Let desktop apps access your camera**. Zoom and the classic Teams desktop client sit under this heading, not in the list above — this is the single most common miss.
6. Restart the app afterwards; permission changes are not picked up while it is running.

## Step 3: Find What Is Already Using the Camera
1. Close **every** app that could claim it: Camera, Skype, Discord, OBS, Snap Camera, NVIDIA Broadcast, Windows Hello sign-in prompts, and other browser tabs on a video call.
2. Press **Ctrl + Shift + Esc** → **Details** tab, and end any leftover **Teams.exe**, **ms-teams.exe**, **Zoom.exe**, or **obs64.exe** processes.
3. Check **Settings** → **Privacy & security** → **Camera** → **Recent activity**, which shows which app last used it and when.
4. Reboot if in doubt — it releases every stream cleanly.

## Step 4: Select the Right Camera Inside the App
Virtual cameras insert themselves at the top of the device list and win by default.

1. **Teams:** click **⋯** → **Settings** → **Devices**, and set **Camera** to the physical device, not "OBS Virtual Camera" or "NVIDIA Broadcast".
2. **Zoom:** click the **^** next to **Stop Video** → **Video Settings**, and pick the correct camera from the dropdown.
3. Uninstall virtual camera software you no longer use: **Settings** → **Apps** → **Installed apps**.
4. In a browser, click the camera icon in the address bar and confirm both the permission and the selected device.

## Step 5: Check the Physical Privacy Shutter and Key
1. Many laptops have a **sliding shutter** over the lens — check it is open.
2. Others have a **function key** (often **F8** or **F10**, with a camera icon) that disables the camera in firmware. Press **Fn** + that key.
3. Some ThinkPads and Dell models also have a camera toggle inside the vendor utility (Lenovo Vantage, Dell Optimizer) — check there.
4. External webcams: try a different **USB port on the back of the PC**, not a hub or monitor.

## Step 6: Reset or Repair the App
1. **Settings** → **Apps** → **Installed apps** → find Teams or Zoom → **⋯** → **Advanced options** → **Repair**, then **Reset** if repair does not help.
2. For classic Teams, clearing the cache often fixes device selection: close Teams, then delete the contents of
   ```
   %appdata%\Microsoft\Teams
   ```
3. For Zoom, sign out, quit fully from the system tray, and sign back in.
4. Update the app itself — both clients ship device fixes regularly.
5. If the Store will not update apps: [fix the Microsoft Store not working](https://www.mytechnician.tech/tips/fix-microsoft-store-not-working-windows-11/).

## Step 7: Reinstall the Camera Driver
1. Right-click **Start** → **Device Manager**.
2. Expand **Cameras** — and also check **Imaging devices** and **Sound, video and game controllers**.
3. Right-click the camera → **Uninstall device**. Tick **Attempt to remove the driver for this device** only if you have the vendor driver ready.
4. Restart. Windows reinstalls the standard driver automatically.
5. If it does not appear, click **Action** → **Scan for hardware changes**.
6. On a laptop, install the camera driver from the manufacturer's support page for your exact model: [how to update outdated drivers](https://www.mytechnician.tech/tips/how-to-update-outdated-drivers/).

## Step 8: Check Antivirus Webcam Protection
Several security suites include camera blocking that reports itself as a Windows error.

1. Look for "webcam protection", "camera guard", or similar in Kaspersky, Bitdefender, ESET, or Norton.
2. Add Teams and Zoom to its allow list, or disable the feature briefly to confirm it is the cause.
3. Also check **Windows Security** → **Virus & threat protection** → **Protection history** for a block entry.
4. If the built-in protection is not running properly: [fix Windows Defender not working](https://www.mytechnician.tech/tips/fix-windows-defender-not-working/).

## Step 9: Repair Windows and Roll Back a Bad Update
1. In **Terminal (Admin)**:
   ```
   sfc /scannow
   ```
   ```
   DISM /Online /Cleanup-Image /RestoreHealth
   ```
2. Reboot and re-run `sfc /scannow`: [how to run SFC and DISM](https://www.mytechnician.tech/tips/how-to-run-sfc-dism-repair-windows-11/).
3. If video broke right after a Windows update, remove it: [fix Windows 11 after a bad update](https://www.mytechnician.tech/tips/fix-windows-11-after-bad-update-rollback/).
4. Check the Application log for the faulting module: [how to use Event Viewer to find why your PC crashed](https://www.mytechnician.tech/tips/how-to-read-event-viewer-find-crash-cause/).

## What Not to Do
* **Don't leave "Let desktop apps access your camera" off** and then hunt for driver problems. Check it first — it costs ten seconds.
* **Don't run two conferencing apps at once** and expect both to see the camera. Most webcams support one consumer at a time.
* **Don't install a "webcam fixer" utility.** Everything above uses built-in tools.
* **Don't disable Windows Hello** to free the camera. It releases the stream automatically once you are signed in — see [fix Windows Hello not working](https://www.mytechnician.tech/tips/fix-windows-hello-not-working/) if it does not.

## Still Not Working?
Test the same account in the **browser version** of Teams or Zoom. If the browser works and the desktop app does not, reinstall the desktop client. If neither works but the Camera app does, create a new Windows user account and test there — that separates a damaged profile from an app fault.

For an external webcam that fails on every PC, the device or its cable has failed.
