Why Does My Webcam Not Work on Zoom Calls?
Joining a Zoom call only to see a black screen instead of your video, or finding Zoom can't detect your camera at all, is a common and frustrating issue, especially right before a meeting. Fortunately, this problem is usually traceable to permissions or settings rather than actual hardware failure.
Camera privacy permissions are one of the most common causes, since Windows and Mac both require explicit permission for apps like Zoom

Another app already using your camera in the background, such as another video call app left open, can block Zoom since most webcams only support one active connection at a time. Outdated webcam drivers or outdated Zoom software can also cause detection issues. Lastly, selecting the wrong camera source within Zoom's settings is surprisingly common on laptops with both a built-in and external webcam.
Start by checking if any other app is currently using your camera, such as Skype, Teams, FaceTime, or even a browser tab with an open video chat. Close these completely, not just minimize them, since background access to your camera prevents Zoom from using it simultaneously.
Check your camera privacy settings next. On Windows, go to Settings > Privacy > Camera, ensure "Allow apps to access your camera" is turned on, and scroll down to confirm Zoom specifically has permission enabled. On Mac, go to System Settings > Privacy & Security > Camera, and ensure Zoom is checked in the list of allowed apps.
Within Zoom itself, click the small arrow next to the camera icon in the meeting controls (or go to Settings > Video) and confirm the correct camera is selected, especially if you have multiple camera options like a built-in laptop camera and an external USB webcam.
Restart Zoom completely, and if that doesn't help, restart your laptop entirely, since this clears temporary conflicts between apps competing for camera access that an app restart alone sometimes won't fully resolve.
Check for pending Zoom updates by opening the Zoom app, clicking your profile picture, and selecting "Check for updates," since outdated versions occasionally have compatibility issues with camera drivers following operating system updates.
Update your webcam drivers through Device Manager (Windows) by expanding "Cameras" or "Imaging devices," right-clicking your camera, and selecting "Update driver." For built-in cameras, drivers from your laptop manufacturer's website are typically more reliable than generic Windows drivers.
Avoid testing your camera in too many different apps simultaneously while troubleshooting, as this can create confusing conflicts that make it harder to pinpoint the actual cause. Close everything except Zoom while testing.
If your camera still isn't detected after closing other apps, checking permissions, and updating drivers, test it within Windows' built-in Camera app to see whether the issue is specific to Zoom or system-wide. If it fails everywhere, the webcam hardware may need professional inspection or replacement.
Most Zoom camera issues come down to privacy permissions or another app silently using the camera, both quick to identify and fix once you know where to check.
