![Webcam Not Working? 12 Ways to Fix It on Windows and Mac [2026]](/images/blog/webcam-not-working-fix-hero.webp)
You join a Zoom call, a Teams meeting, or open FaceTime, and instead of your face there's a black rectangle, a spinning loader, or an error saying the camera "could not be started." Webcam failures are one of the most common tech complaints we field at IT Cares, and they almost always strike at the worst possible moment — five minutes before a client call, a job interview, or a family video chat. The good news: the overwhelming majority of webcam problems are caused by software settings, not broken hardware, and most are fixable in under two minutes.
This guide covers all 12 fixes, ordered from the fastest and most common (privacy permissions, app conflicts) to the more involved (driver reinstalls, Mac-specific Terminal fixes, and how to tell if the camera itself is dead). It applies to built-in laptop webcams and external USB webcams (Logitech, Razer, generic UVC cameras) on both Windows and Mac.
Webcam problems tend to cluster around a handful of moments: right after a Windows or macOS update, right after installing a new meeting app or a competing one (Slack, Discord, OBS) that also wants camera access, or the first time you plug in a new external camera. Knowing which of these applies to your situation is often the fastest way to jump straight to the right fix rather than working through all twelve in order. If your camera stopped working immediately after a system update, start with Fix 1 and Fix 5. If it's a brand-new external webcam that has never worked at all, start with Fix 4 and Fix 11. If it worked five minutes ago and now shows an "in use" error, start with Fix 3.
The #1 rule of webcam troubleshooting
A webcam can only be used by one application at a time. If Zoom is still running in your system tray, or a browser tab from an earlier video call is still open, no other app will be able to access the camera — even if it looks closed. Always check for hidden background processes before assuming the hardware is broken.
Common Webcam Error Messages and What They Mean
| Error / Symptom | Most Likely Cause | Fix to Try First |
|---|---|---|
| "Camera is in use by another application" | Another app (or hidden background process) has an exclusive lock on the camera | Fix 3 — close conflicting apps |
| "We can't find your camera" / "No camera found" | Driver missing, disabled in Device Manager, or privacy setting off | Fix 1 or Fix 5 |
| Black screen but no error message | App-specific camera selection pointing to the wrong device | Fix 4 |
| Camera works in one app, not another | Per-app privacy permission is disabled for that specific app | Fix 1 |
| Camera worked yesterday, dead today | Recent Windows/macOS update reset driver or permission state | Fix 5, Fix 7 |

12 Fixes for a Webcam That Isn't Working
Check Camera Privacy Permissions in Windows
This is the single most common cause of webcam failures on Windows 10 and 11. Go to Settings > Privacy & Security > Camera. Make sure Camera access is turned on at the top. Scroll down to Let apps access your camera and confirm it's enabled, then check the individual app list below — Zoom, Teams, Chrome, and any other app you use for calls must each be individually toggled on. A single Windows feature update can silently reset these toggles to off, which is why a webcam that worked fine last week can suddenly stop working with zero hardware changes.
Check Camera Privacy Permissions on Mac
Go to Apple menu > System Settings > Privacy & Security > Camera. You'll see a list of every app that has ever requested camera access. Toggle on the apps you use (Zoom, Teams, FaceTime, your browser). If an app isn't in the list at all, it has never asked for permission — quit and reopen that app so it triggers the permission prompt again, then click Allow when it appears. macOS updates occasionally reset these permissions, especially after a major version upgrade (e.g. moving from Sonoma to Sequoia).
Close Every App That Might Be Using the Camera
Webcams support only one active connection at a time. Open Task Manager (Ctrl+Shift+Esc on Windows) or Activity Monitor (Mac) and look for Zoom.exe, Teams.exe, Skype.exe, Discord.exe, or any browser process — even if you don't see their windows open, they may be running in the background or system tray. End each of these tasks, wait 10 seconds for the camera driver to fully release, then reopen only the one app you actually need. This single step resolves the "camera is in use by another application" error in the majority of cases we see.
Check the App's Own Camera Source Setting
If you have more than one camera connected (a laptop's built-in webcam plus an external USB webcam, or a virtual camera from streaming software like OBS), the meeting app might be pointed at the wrong one. In Zoom: Settings > Video > Camera dropdown. In Teams: Settings > Devices > Camera dropdown. Select the correct physical camera from the list. Also check for a physical privacy shutter or lens cap on external webcams — several popular models (Logitech Brio, Razer Kiyo) include a sliding cover that's easy to forget about.
Update the Webcam Driver via Device Manager
Right-click the Start button > Device Manager > expand Cameras (or Imaging devices on older Windows 10 builds). Right-click your webcam > Update driver > Search automatically for drivers. If Windows says the best driver is already installed but the camera still doesn't work, that's your cue to move to Fix 6 (full driver reinstall) instead, since a corrupted driver can report as "up to date" while still being broken. Also check whether a yellow warning triangle or a down-arrow icon appears next to the camera entry in Device Manager — a yellow triangle indicates a driver conflict or error code that Windows can usually describe if you double-click the device and check the Device Status box, while a down-arrow means the device is disabled and simply needs to be re-enabled via right-click.
Uninstall and Reinstall the Camera Driver
In Device Manager, right-click the camera under Cameras and select Uninstall device. Check the box for Delete the driver software for this device if offered, then click Uninstall. Restart your computer — Windows will automatically detect the camera and reinstall a fresh driver on boot. This clears out corrupted driver state that a simple "Update driver" click can't fix, and it's the single most effective fix for a built-in laptop camera that Device Manager shows with a yellow warning triangle.
Run the Windows Camera Troubleshooter
Go to Settings > System > Troubleshoot > Other troubleshooters, find Camera, and click Run. This built-in tool automatically checks for disabled devices, missing drivers, and conflicting privacy settings, and can fix several of these issues without you having to dig through menus manually. It won't catch everything in this guide, but it's a fast first pass that resolves the issue outright for a meaningful share of users.
Check Antivirus and Firewall Webcam Protection
Security suites with a webcam-protection feature (Norton, Bitdefender, Kaspersky, McAfee, and some corporate endpoint protection tools) can silently block camera access from apps they don't recognize or haven't explicitly whitelisted. Open your antivirus dashboard, look for a section called Webcam Protection, Privacy Shield, or similar, and add your meeting app to the allowed list. If you're on a work laptop, this is frequently managed centrally by IT policy — contact your admin if you can't find or change the setting yourself.
Test in the Built-In Camera App First
Before troubleshooting a specific app like Zoom, open the Camera app that ships with Windows, or Photo Booth/FaceTime on Mac. If the image appears there, the hardware and driver are fine, and the problem is isolated to the specific app's settings or permissions — go back to Fix 1 and Fix 4. If the built-in app also fails, the issue is at the system level, and Fixes 5–8 are the right next steps. This single diagnostic step saves significant time because it immediately splits every possible cause into two clean categories — "it's the meeting app" versus "it's the system" — instead of guessing at driver issues when the real problem is a single disabled permission toggle inside Zoom itself, or vice versa.
Check for a Physical Privacy Shutter or Blocked Lens
It sounds obvious, but it's one of the most common support calls we get: many laptops (ThinkPad, some Dell and HP models) and most premium external webcams include a physical sliding shutter over the lens for privacy. If this is closed, the camera will either show black or fail to initialize entirely — and no software fix will resolve it. Also check for a plastic film sticker still covering a brand-new webcam, or a paper privacy sticker applied over an older laptop's camera.
For External USB Webcams: Try a Different Port and Cable
Some USB 3.0 ports don't provide reliable power delivery for older UVC (USB Video Class) webcams, causing intermittent disconnects. Try a different USB port — ideally a USB 2.0 port if your laptop has one — and a different cable if the webcam uses a detachable USB-C or micro-USB cable. In Device Manager, go to Universal Serial Bus controllers, right-click each USB Root Hub > Properties > Power Management, and uncheck Allow the computer to turn off this device to save power. If the webcam works on a different computer entirely, the fault is confirmed to be driver or port-related, not the camera itself.
Mac-Specific: Reset the Camera Process via Terminal
On Mac, camera lockups are often caused by a stuck system process. Open Terminal and run sudo killall VDCAssistant (Intel Macs) or sudo killall AppleCameraAssistant (Apple Silicon), then reopen your meeting app — this forces macOS to reinitialize the camera hardware layer. If that doesn't help, check Apple menu > About This Mac > check for macOS updates, since Apple has shipped several camera-related bug fixes in past point releases. As a last resort, a full restart (not sleep — a genuine shutdown and cold boot) resolves camera issues that persist after every other fix on this list.
Built-in laptop camera vs. external USB webcam: different failure points
A built-in laptop webcam is soldered to the motherboard and almost never fails physically before the rest of the laptop does — when it stops working, it's a driver or permission issue about 95% of the time. External USB webcams have more failure points: the USB cable, the port, the driver, and the camera's own internal electronics. If an external webcam fails after working fine for months, test it on a second computer before assuming it's dead — a bad cable or a power-saving USB port is far more common than a genuinely broken camera.
Webcam Issues in Zoom, Microsoft Teams, and Google Meet: App-Specific Quirks
While the fixes above solve the vast majority of webcam problems at the operating-system level, each meeting platform has its own quirks worth knowing about, especially if the camera works fine in one app but fails in another.
Zoom caches video device settings aggressively, which means a webcam swap (unplugging one USB camera and plugging in another) sometimes isn't picked up until you fully quit and relaunch Zoom — simply leaving and rejoining a meeting is not enough. Zoom also has a setting under Settings > Video > "HD" that can cause a black screen or freeze on older or lower-power webcams that can't sustain HD frame rates; unchecking it often resolves choppy or frozen video that looks like a camera failure but is actually a bandwidth/processing issue. If Zoom shows a black preview specifically during screen sharing while the camera works normally otherwise, this is typically a hardware-acceleration conflict — Settings > Video > uncheck "Enable hardware acceleration for video processing".
Microsoft Teams ties camera permission to your Microsoft 365 or work/school account profile in addition to the OS-level permission, which means a camera that works in your personal Teams app might still fail in a work-managed Teams install because a Conditional Access or Intune device policy is blocking it. If you're on a company laptop and none of the fixes above work, this is worth raising with your IT department directly rather than continuing to troubleshoot locally. Teams also occasionally gets stuck with a corrupted local cache — closing Teams completely (including the background process, since it minimizes to tray by default) and clearing the cache folder at %appdata%\Microsoft\Teams forces a clean reload of camera device detection.
Google Meet and other browser-based video tools rely entirely on the browser's own camera permission, which is separate from both the Windows/Mac system permission and the meeting app's internal setting — three layers deep. In Chrome, check Settings > Privacy and security > Site settings > Camera and make sure meet.google.com isn't in the "Not allowed" list. A padlock or camera icon in the address bar during a call also lets you grant or fix permissions on the spot without digging through settings menus.
How to Prevent Webcam Problems Before Your Next Important Call
Most webcam failures happen at the worst possible time because they're never tested until the moment they're needed. A two-minute pre-call check eliminates the vast majority of last-minute scrambles:
- Test 10 minutes before, not 10 seconds before. Open the built-in Camera app (or your meeting app's test-call feature — Zoom and Teams both offer one) with enough buffer time to actually troubleshoot if something's wrong.
- Fully quit apps after every call, don't just close the window. Zoom, Teams, and Skype all default to minimizing to the system tray, which is the single biggest cause of "camera in use" errors on the next call.
- Keep one app as your default for camera-based calls where possible, rather than switching between Zoom, Teams, and browser-based tools throughout the day — each switch is an opportunity for a stuck permission or lock.
- Restart your computer at least once a week. This clears stuck background services (like the Windows Camera Frame Server) before they cause a problem, rather than after.
- For external webcams, leave them plugged into the same USB port every time. Windows treats a webcam plugged into a different port as a "new" device in some cases, which can silently reset driver settings and privacy permissions for that specific connection.
When to Replace a Webcam Instead of Continuing to Troubleshoot
If you've worked through every fix above and the camera still fails — particularly if it also fails in the built-in Camera/Photo Booth app, on a different USB port, and on a second computer — the hardware itself is likely the point of failure. Built-in laptop webcams that are physically dead usually require a technician to open the laptop and replace the camera module or the ribbon cable connecting it to the motherboard, since the part itself is inexpensive but not accessible without disassembly. External USB webcams are far cheaper to simply replace outright: a reliable 1080p external webcam costs $30–$80, which is almost always less than the labor cost of diagnosing and repairing an aging unit. As a rule of thumb, if an external webcam is more than 4–5 years old and failing intermittently even after a driver reinstall, replacement is usually the more cost-effective path forward.
Why "Camera Is in Use by Another Application" Keeps Coming Back
This is the single most frustrating webcam error because it implies the fix is obvious — close the other app — when the real culprit is often invisible. Windows runs a background service called the Windows Camera Frame Server, which manages camera access between multiple apps. When this service gets stuck (which can happen after a crashed app, an interrupted video call, or a Windows update mid-restart), it continues reporting the camera as "in use" even though nothing visible is actually using it.
To fix a stuck Frame Server: press Win + R, type services.msc, press Enter. Find Windows Camera Frame Server in the list, right-click it, and select Restart. If the service isn't running at all, right-click and select Start. This resolves the lock without requiring a full system restart, and it's worth trying before you reinstall any drivers. If the service is set to Manual startup type and keeps stopping on its own, changing it to Automatic (right-click > Properties > Startup type) prevents the issue from recurring after every reboot.
macOS has an equivalent, less visible mechanism: a system process called VDCAssistant that mediates camera access between apps, referenced earlier in Fix 12. Unlike Windows, macOS doesn't expose a friendly services panel for it, which is exactly why the Terminal command is the standard fix rather than a GUI toggle. Both operating systems ultimately solve the same underlying problem — a background broker process losing track of which app currently "owns" the camera — they just require different tools to reset.

Webcam Quirks by Laptop Brand
Beyond the universal Windows and Mac fixes, several laptop manufacturers add their own camera management layers that can interfere with standard troubleshooting:
Dell laptops with the Dell Optimizer or Dell Peripheral Manager software installed sometimes apply their own camera framing and auto-exposure settings on top of the Windows driver. If the camera image looks washed out, overly dark, or has a visible digital zoom applied that you didn't set, open Dell Peripheral Manager and check the camera tab for an "auto framing" or "background blur" toggle that may need to be disabled for compatibility with certain meeting apps.
HP laptops with the HP Client Security or HP Wolf Security suite include a camera privacy toggle called HP Privacy Camera that is separate from both the physical shutter and the Windows privacy setting — a third layer that's easy to overlook. Check the HP Support Assistant or the function-key camera indicator (usually F9 or a dedicated camera key) to confirm it isn't disabled at this level.
Lenovo ThinkPad models are well known for their physical ThinkShutter camera cover, which is the single most common cause of "camera not detected" tickets we receive for this brand — always check it first before any software troubleshooting. Lenovo Vantage software also includes its own camera settings panel that can override Windows-level driver updates, so if a driver update through Device Manager doesn't stick, check Lenovo Vantage's device settings for a conflicting override.
MacBook models rarely have camera hardware failures given the sealed, non-removable design, but the FaceTime HD camera can be affected by a stuck Continuity Camera feature on newer macOS versions, where the Mac tries to automatically use a nearby iPhone as a webcam instead of its own built-in camera. If your MacBook's camera seems to disappear entirely from an app's device list, check whether an iPhone is nearby and signed into the same Apple ID with Wi-Fi and Bluetooth on — disconnect or move the iPhone out of range to force the Mac back onto its own built-in camera.

Frequently Asked Questions
Why does my webcam say "camera is in use by another application" when nothing is open?
A background process usually still has a lock on the camera even though nothing is visibly open. The most common hidden culprits are Zoom or Teams minimized to the system tray after you clicked the X instead of fully quitting, an old browser tab with a previous video call still active, the Windows Camera Frame Server background service getting stuck, or antivirus software with webcam protection actively scanning the feed. Open Task Manager, end any Zoom.exe, Teams.exe, or relevant browser processes, then restart the Windows Camera Frame Server service through services.msc and try again.
How do I know if my webcam is disabled by my antivirus?
Most security suites with a webcam protection or privacy shield feature — Norton, Bitdefender, Kaspersky, and McAfee all include one — display a pop-up or a blocked-icon notification the moment an app tries to access the camera without prior approval. Open your antivirus dashboard and look for a Webcam Protection or Privacy section, where you'll typically find a list of allowed and blocked applications that you can edit directly. If no notification appeared but the camera still fails to start, disable webcam protection for two minutes as a diagnostic test; if the camera works during that window, you've confirmed the cause and can safely add the specific app to your permanent exception list.
Why does my external USB webcam work on one laptop but not another?
This points to a driver or USB power configuration issue rather than a physically broken camera. Windows installs a generic USB Video Class driver automatically for most webcams, but this generic driver occasionally conflicts with a specific laptop's power-saving settings. Open Device Manager, expand Universal Serial Bus controllers, right-click each USB Root Hub, choose Properties, then the Power Management tab, and uncheck "Allow the computer to turn off this device to save power." It's also worth trying a different USB port on the same machine — USB 3.0 ports occasionally have compatibility quirks with older USB Video Class webcams that a USB 2.0 port handles without issue.
Do I need to update webcam drivers regularly?
Not on a fixed schedule, but there are specific moments when you should check. Update immediately after installing a Windows feature update, since these sometimes silently reset driver versions or privacy toggles, and after any macOS or Windows version released within the last 30 days, since early builds occasionally ship with known camera regressions that get patched quickly. Built-in laptop webcams generally update automatically through Windows Update without any action needed on your part. External webcams from brands like Logitech or Razer benefit noticeably from installing the manufacturer's companion software — Logitech G HUB or Logi Options+, for example — which keeps drivers current in the background and also unlocks manual exposure and framing controls the generic Windows driver doesn't expose.
How can I test if my webcam is physically broken vs a software issue?
Open the built-in camera application — the Windows Camera app on Windows, or Photo Booth and FaceTime on Mac — without opening Zoom, Teams, or any third-party software first. If a clear image appears in the built-in app, the hardware, driver, and connection are all functioning correctly, and the problem is isolated to permissions or settings specific to your meeting app; go back to Fix 1 (privacy permissions) and Fix 4 (app camera source selection). If the built-in app also fails to show any image or throws its own error, the fault sits at the driver or hardware level rather than being app-specific, and Fixes 5 through 8 in this guide (driver update, reinstall, troubleshooter, and antivirus check) are the correct next steps to work through in order.

Fix 3 saved my job interview. Teams kept saying camera was in use and I couldn't figure out why since I only had one window open. Turned out Slack had grabbed the camera from a huddle I'd closed two days earlier. Killed the process in Task Manager and it worked instantly.
The Windows Camera Frame Server tip is gold. I've had this "in use by another application" error on and off for months and always just restarted the whole laptop. Restarting that one service through services.msc takes 10 seconds and works every time now.
Felt silly after reading Fix 10 — my ThinkPad has a physical shutter over the camera and I'd bumped it closed without noticing. Fifteen minutes of troubleshooting for a two-second fix. Still, glad this guide mentioned it because I would never have thought to check.
