Control access to your camera on Mac
Some apps and websites can use your camera to take photos or video. You can decide which apps are allowed to use the camera on your Mac.
On your Mac, choose Apple menu > System Preferences, click Security & Privacy, then click Privacy.
Select the tickbox next to an app to allow it to access your camera.
Deselect the tickbox to turn off access for that app.
If you turn off access for an app, you’re asked to turn it on again the next time that app tries to use your camera.
If you allow third-party apps or websites to use your camera, any information they collect is governed by their terms and privacy policies. It’s recommended that you learn about the privacy practices of those parties.
For systems administrators who want information about deploying security settings, see the macOS Deployment Reference.
