A webcam not working on Zoom or Teams usually comes down to something simple. It’s often a blocked privacy setting, another app holding onto the camera, or the wrong device selected in the app itself. Work through the checks below in order. You’ll almost always find the cause before you need to touch a driver. This matters even more if you’re getting ready for a remote job interview and the camera decides to act up an hour beforehand.
Quick Answer: Webcam Not Working on Zoom or Teams
- Check for a physical privacy shutter or camera function key first.
- Check Windows camera privacy settings.
- Close other apps that might be using the camera.
- Confirm the correct camera is selected inside Zoom or Teams.
- Check Device Manager if the camera doesn’t show up at all.
- Check browser permissions if you’re joining through a web link.
1. Webcam Not Working on Zoom or Teams? Check for a Physical Block First
Before touching any settings, rule out the obvious.
Many laptops — especially recent Lenovo, HP, and Dell models — have a physical privacy shutter that slides over the lens. Check the top bezel of the screen. Some laptops also have a camera on/off key on the keyboard. It’s often paired with the Fn key and marked with a small camera icon. If someone (or you, absentmindedly) pressed it, the camera won’t turn on no matter what software settings say.
A simple restart also clears out background processes that can be quietly locking the camera.
2. Test the Camera Outside Zoom or Teams First
Before troubleshooting either app specifically, check whether Windows can see the camera at all.
Open the Start menu, search for Camera, and open the built-in Camera app. If your video shows up, the hardware and drivers are fine. The problem is specific to Zoom, Teams, or your browser. If you get a black screen or an error instead, the issue sits at the Windows or driver level — skip ahead to the Device Manager section below.
3. Check Windows Camera Privacy Settings
Windows can block camera access system-wide, which is one of the most common reasons behind a webcam not working on Zoom or Teams even though the hardware itself is fine.
Press Windows key + I to open Settings, then go to Privacy & security → Camera. Turn on Camera access, then Let apps access your camera. Scroll down and confirm Let desktop apps access your camera is also on — Zoom and Teams both rely on that last toggle specifically.
Fully close and reopen whichever app you’re using after changing these settings; they don’t always take effect on an app that’s still running.
4. Close Other Apps Using the Camera
Most webcams can only stream to one application at a time. Skype, Discord, another browser tab, or a program like OBS Studio can all hold onto it. If one of them already has it, Zoom or Teams won’t be able to get a picture.
Check your system tray for anything camera-related running in the background, and close it. Open Task Manager (Ctrl + Shift + Esc) if you’re not sure what’s running. If you use virtual camera software like Snap Camera or ManyCam, check that it isn’t the default selected device. Pick your physical camera explicitly instead.
5. Check Device Manager
If the Camera app itself shows a black screen, a driver issue is the likely cause of the webcam not working on Zoom or Teams.
Right-click the Start button, open Device Manager, and expand Cameras (some systems file it under Imaging devices instead). Right-click your webcam. If it says disabled, choose Enable device. If it’s already enabled but not working, right-click again and choose Update driver → Search automatically for drivers.
When that doesn’t fix it, choose Uninstall device, restart your PC, and Windows will typically reinstall it automatically. If it doesn’t, install the driver from your laptop manufacturer’s support site rather than a third-party download.
6. Select the Correct Camera in Zoom
If Windows sees the camera fine but Zoom doesn’t, Zoom may simply be pointed at the wrong device.
Open Zoom, click your profile icon, go to Settings → Video, and check the Camera dropdown. If more than one option is listed, select your actual webcam and confirm the preview shows your image. If the preview stays black, try switching to a different listed camera and back again — that alone sometimes resets the connection.
7. Select the Correct Camera in Teams
Teams has the same kind of setting, and it’s worth checking separately since Teams and Zoom don’t always agree on which camera is “default.”
Open Teams, click your profile picture, go to Settings → Devices, and check the camera section. Select your webcam from the dropdown and confirm the preview updates. On the meeting pre-join screen, double-check the camera toggle is on. Confirm the right device is chosen before you actually enter the call.
8. Check Browser Permissions (Chrome and Edge)
If you’re joining through a browser link instead of the desktop app, the browser has its own separate camera permissions. Windows allowing access doesn’t automatically mean the browser will too.
In Chrome: go to Settings → Privacy and security → Site settings → Camera. Make sure Sites can ask to use your camera is on. Check that zoom.us or teams.microsoft.com isn’t sitting in the blocked list.
In Edge: go to Settings → Cookies and site permissions → Camera. Confirm sites can ask for access, and remove Zoom or Teams from the blocked list if it’s there.
You can also click the padlock icon in the address bar on the meeting page itself to check and change the camera permission directly, then refresh.
9. Webcam Not Working on Zoom or Teams? Find Which App Is the Problem
If the camera works in one place but not another, use that as a shortcut instead of troubleshooting blind.
| Works in | Fails in | Focus on |
|---|---|---|
| Windows Camera app | Zoom | Zoom’s camera selection or permissions |
| Windows Camera app | Teams | Teams’ camera selection or permissions |
| Zoom | Teams | Teams’ device configuration |
| Teams | Browser | Browser site permissions |
| Nothing works anywhere | — | Windows settings, driver, or hardware |
This narrows things down fast rather than repeating every fix for every app.
10. External USB Webcam vs. Built-In Laptop Camera
The two have slightly different failure points.
External USB webcams should be plugged directly into a port on the laptop itself, not an unpowered USB hub. Hubs often can’t supply enough power for HD video, which causes freezing or crashes. If Windows doesn’t detect it, try a different port, then check Device Manager as in step 5.
Built-in cameras connect through the laptop’s hinge. A camera that cuts out specifically when you tilt the screen may point to a damaged internal cable rather than a software issue. Built-in cameras also sometimes route through manufacturer software, like Lenovo Vantage or similar utilities. That software often has its own privacy toggle, worth checking separately from Windows settings.
FAQ: Webcam Not Working on Zoom or Teams
Why is my webcam showing a black screen on Zoom or Teams? The most common causes are a physical privacy shutter, a camera function key toggled off, another app already using the camera, or the wrong camera selected in the app. Work through those first before assuming it’s a hardware fault.
How do I turn on camera permissions in Windows 11? Go to Settings → Privacy & security → Camera, turn on Camera access, and make sure Let desktop apps access your camera is also switched on. That second setting is the one people most often miss.
Why does my camera work in one app but not another? Each app has its own camera selection and its own permissions. Test the built-in Windows Camera app first to rule out hardware, then check the specific app’s video settings.
Can antivirus software block a webcam? Yes. Some security suites include webcam protection that blocks apps from accessing the camera unless you’ve allowed them. Check your antivirus settings and confirm Zoom, Teams, and your browser are allowed.
Why is my external USB webcam not detected? Try a different USB port directly on the laptop rather than a hub, then check Device Manager for the device and update its driver if needed.
More Webcam Not Working on Zoom or Teams Questions
Why does my webcam work in the browser but not the desktop app (or the reverse)? Desktop apps and browsers use separate permission systems. If one works and the other doesn’t, check the permissions for whichever one is failing rather than assuming a hardware problem.
How do I test my webcam before a job interview? Open the Windows Camera app first to confirm the hardware works. Then check the preview inside Zoom or Teams before the call starts — testing five or ten minutes early gives you time to fix anything that comes up.
Do I need to buy a new webcam if none of this works? Not usually. Most webcam problems are permissions, app settings, or driver issues rather than failed hardware. If an external webcam still doesn’t work after testing it on another computer, that’s a stronger sign the hardware itself has failed.
Webcam Not Working on Zoom or Teams: Before Your Next Call
Check the camera before the meeting, not during it. A minute spent testing the preview in Zoom or Teams beforehand saves the scramble of troubleshooting while someone’s waiting for you to join. If the laptop itself feels sluggish during calls even once the camera is working, that’s a separate issue — our complete guide to speeding up a slow laptop covers it, including a section on video call lag specifically.
