Use an external camera with Mac
Many Mac computers have a built-in camera located near the top edge of the screen, but you can also use an external camera with your Mac.
Connect an external camera
Connect the camera’s cable to a port on your Mac. See About the video ports on Mac.
If the camera has a connector that doesn’t match the port you want to connect it to, you may be able to use it with an adapter. See the Apple Support article Adapters for the Thunderbolt 4, Thunderbolt 3, or USB-C port on your Mac.
Wait 10 to 15 seconds for your Mac to recognize the camera.
For more information about connecting your external camera, see the manufacturer’s instructions.
