Apple’s iPhones have some of the best cameras in the smartphone market, however, that hasn’t always been the case for MacBooks and iMacs.
If you are one of these unsatisfied customers, you have probably thought about or already bought an external webcam.
You should also check the resolution of your external webcam and compare it with your Mac’s webcam resolution.
We recommend a 1080p webcam (4K is excessive for most people), although resolution isn't everything. A 1080p external webcam with a larger sensor will beat
the MacBook Pro's webcam.
1. Before using an external webcam, make sure your macOS computer has the right port. USB-A, USB-C, Thunderbolt, or DisplayPort, depending on the webcam.
2. Plug in your webcam and open FaceTime. Allow your computer to load for a moment as it connects to your integrated webcam.
3. Next, click “Video” on the menu bar at the top of your screen.
4. Under “Cameras”, select the external webcam you plugged in. Wait for FaceTime to load again as it switches video sources. That’s it; you are now using an external webcam for FaceTime.
