Zoom Camera Not Working During Calls: 8 Fixes That Actually Work
Table of Contents
Your Zoom camera showing a black screen, freezing, or not turning on at all right before an important call is one of the most common — and most nerve-wracking — Zoom problems. It always seems to happen at the worst possible time: two minutes before a client call, or right as a job interview is starting. The good news is that it’s almost always fixable in under five minutes once you know where to look.
I’ve run into this exact problem more times than I’d like to admit — usually because I forgot to close another app that was already using the camera. Nine times out of ten, the fix is one of the first three on this list, so start from the top and work your way down.
Why This Happens
Zoom’s camera problems usually come down to one of a handful of causes: another app already has a lock on your camera, Zoom doesn’t have camera permission on your device, the wrong camera is selected in Zoom’s own settings, your camera drivers are out of date, or — less commonly — there’s a genuine hardware or connection issue with an external webcam.
What makes this frustrating is that the symptom looks the same regardless of the cause: a black rectangle where your video should be. So instead of guessing, it’s worth working through these fixes in order, since the first few take seconds and solve the problem most of the time.
Step-by-Step Fixes
1. Close other apps using your camera
Only one application can access your webcam at a time on most operating systems. If Microsoft Teams, Skype, FaceTime, or even a browser tab (like a Google Meet call you forgot to close) is running in the background, Zoom simply won’t be able to grab the camera. Close every other app that might be touching the camera, then restart Zoom completely — not just the window, the whole application.
2. Check Zoom’s camera permission
On Windows, open Settings → Privacy & Security → Camera, and make sure “Camera access” is turned on, then scroll down and confirm Zoom specifically is allowed in the app list. On Mac, open System Settings → Privacy & Security → Camera, and make sure the toggle next to Zoom is switched on. If you just enabled it, quit Zoom entirely and reopen it — permission changes don’t always apply to an app that’s already running.
3. Select the correct camera inside Zoom
If you own more than one camera — say, a laptop’s built-in camera plus an external webcam — Zoom might be pointed at the wrong one. Open Zoom, click your profile picture, go to Settings, then the Video tab. Use the Camera dropdown to pick the right device, and you should see a live preview appear immediately on the right side of the window.
4. Fully restart Zoom, not just the window
Closing the Zoom window doesn’t always fully quit the app in the background. Open Task Manager (Windows) or Activity Monitor (Mac), search for Zoom, and end the process manually if it’s still running, then reopen Zoom fresh.
5. Update your camera drivers
Outdated drivers are a surprisingly common cause of camera issues, especially right after a Windows update. Right-click the Start button, choose Device Manager, expand Cameras (or Imaging devices), right-click your camera, and select Update driver, then let Windows search automatically.
6. Update Zoom itself
Older Zoom versions sometimes carry unresolved camera bugs that get fixed in later releases. Click your profile picture in Zoom, select Check for Updates, and install anything available before rejoining your call.
7. Restart your computer
It’s the most basic advice on this list, but a full restart clears out any stuck background process that’s silently holding onto your camera. This alone resolves the issue for a surprisingly large number of people, especially after the laptop has been asleep or in low-power mode for a while.
8. Test your camera outside of Zoom first
Before joining your next call, it’s worth confirming your camera actually works independently of Zoom, so you’re not troubleshooting the wrong thing. Our free Camera Test tool runs right in your browser with no download needed — open it, click Start, and you’ll know within seconds whether the hardware itself is fine.
Final Thoughts
If you’ve worked through all eight fixes above and the camera still isn’t showing up, the problem is very likely hardware-related at that point — try the same webcam on a completely different device, or check the cable and USB port if it’s an external camera. In my experience, that’s rare; almost every case I’ve seen personally came down to either a permissions setting or another app quietly holding onto the camera in the background. Keep this page bookmarked — it’s exactly the kind of thing that happens again a few months later, usually right after a Windows or macOS update.
Frequently Asked Questions
Why does my camera light turn on but Zoom still shows a black screen?
This usually means the camera is technically active but is being accessed by two apps at once, or Zoom’s video rendering needs a reset — reopening the Video tab in Settings often fixes it instantly.
Does an external webcam need special drivers for Zoom specifically?
Most USB webcams work fine with the generic drivers your operating system already installs. If yours isn’t detected at all, it’s worth checking the manufacturer’s website for a dedicated driver.
Why does my camera work in every other app except Zoom?
That’s a strong sign it’s a Zoom-specific permission issue rather than a hardware problem — go back and double-check the OS-level camera permission specifically for Zoom, since some systems require you to grant access app by app.
