# Webcam not working in Zoom

_If your camera works in a browser but not in Zoom, the hardware is fine. The problem is Zoom's device selection or its operating system permission, and both are quick to fix._

## Start by proving the camera works

Run the [webcam test](https://www.test-webcamp.com/) before changing any Zoom settings. This takes ten seconds and splits the problem in half:

- **Camera works in the browser** — hardware, cable and driver are all fine. The fault is in Zoom. Continue below.
- **Camera fails in the browser too** — this is a system-level problem, not a Zoom one. See [camera not working on Windows 11](https://www.test-webcamp.com/fix/camera-not-working-windows-11.html).

## 1. Zoom has the wrong camera selected

Open Zoom, click the gear icon, and choose **Video**. The preview at the top shows what Zoom is currently capturing.

Use the camera dropdown to try each entry. Watch out for virtual cameras: entries named "OBS Virtual Camera", "Snap Camera", "NVIDIA Broadcast" or similar produce a black image when their parent application is not running. On a laptop with an external webcam plugged in, both appear, and Zoom does not always pick the one you expect.

## 2. Another application is holding the camera

Most webcams serve one application at a time. Microsoft Teams is the usual offender because it keeps running in the system tray after its window is closed.

Close Teams, Discord, Skype, OBS and any browser tab with a call open, then restart Zoom completely. On Windows, check the system tray and end the processes in Task Manager if necessary.

## 3. The operating system is blocking Zoom specifically

**Permissions are granted per application.** Allowing your browser to use the camera says nothing about Zoom. Each app is listed and toggled separately.

### macOS

Open **System Settings, Privacy & Security, Camera** and make sure **zoom.us** is ticked. macOS requires a full restart of the application afterwards, so quit Zoom with Command-Q rather than closing the window, then reopen it.

### Windows

Open **Settings, Privacy & security, Camera**. Enable **Camera access**, then **Let apps access your camera**, then scroll to the bottom and enable **Let desktop apps access your camera**. Zoom is a desktop app, so that final switch is the one that matters.

## 4. Video is switched off in the meeting

Obvious, but it catches everyone eventually. Check the camera icon in the meeting toolbar for a red line through it. Also check **Settings, Video** for the option that stops video automatically when joining a meeting, which is easy to enable by accident and then forget.

## 5. Reinstall, or use the web client

If everything above checks out, join a test meeting through Zoom's browser client instead. If the camera works there, the desktop installation is damaged and a clean reinstall is the fix. Uninstall Zoom, restart, then install the current version from Zoom's own site rather than an old downloaded installer.

## The same logic applies to other apps

Teams, Google Meet, Discord and Skype all fail in the same ways for the same reasons: wrong device selected, another app holding the camera, or a missing per-application permission. Testing in a browser first is always the fastest way to tell an app problem from a hardware one.
