Camera In Use - How to Fix
Updated: April 2026
Understanding the Problem
Seeing "Camera is being used by another application" means a different program has already claimed exclusive control over your webcam. Unlike microphones, most cameras can only stream to a single app at any given moment.
Typical offenders include:
- Video conferencing apps - Zoom, Microsoft Teams, Skype, Google Meet
- Streaming software - OBS Studio, Streamlabs
- Camera apps - Windows Camera, Photo Booth (Mac)
- Background apps - Some apps run in system tray
Quick Fix
- Close all video apps - Zoom, Teams, Skype, Discord, OBS
- Check the system tray - Right-click and quit any camera-related apps
- Restart your browser
- If nothing works, restart your computer
Find Which App is Using the Camera
Windows 10/11
- Look at the taskbar - when the camera is in use, you'll see a camera icon
- Go to Settings → Privacy & Security → Camera
- Scroll down to see "Recent activity" showing which apps accessed the camera
Windows Task Manager Method
- Press Ctrl + Shift + Esc to open Task Manager
- Look for these apps and end them:
- Zoom Meetings
- Microsoft Teams
- Skype
- Discord
- OBS Studio
- Webex
- Right-click → End Task
Mac
- Look at the menu bar - a green dot appears when camera is in use (macOS Monterey+)
- Open Activity Monitor (search in Spotlight)
- Search for video apps and click X to quit them
- Or use Terminal:
lsof | grep "Camera"
Common Apps to Check
| App | How to Close |
|---|---|
| Zoom | Click profile icon → Sign Out, or quit from system tray |
| Microsoft Teams | Right-click system tray icon → Quit |
| Skype | File → Sign Out, or quit from system tray |
| Discord | Quit from system tray (it runs in background) |
| OBS Studio | Close the application completely |
| Slack | End any active huddle, then quit |
Browser Tab Issues
Sometimes another browser tab is using the camera:
- Close other tabs that might have camera access (other video call sites)
- Check other browser windows
- Close all browser windows and reopen
Prevent Future Issues
- Disable "Start on login" for video apps you don't always need
- Close video apps completely after meetings (they often stay in background)
- Use one video app at a time
Test Your Camera
After closing other apps, test your camera on DoCam.io Webcam Test to verify it's now available.
