I don’t have a camera for the Mac Mini, Will I be able to use my iPhone as my Mac’s camera?

Maybe but it would probably be a better idea to buy a cheap webcam like the Logitech C270 for under £20.

It's very basic and only records 720p but it's better than many expensive 1080p ones with more bells and whistles.

I was so impressed that I bought 2.

Logitech Webcam

This is the kind of quality you will get from the video.

Thanks for asking the question as I have done a bit of research and discovered a FREE app called Iriun which you download on your Mac or PC together with one for your Android or iPhone.

Within 2 minutes I had downloaded them and had my Android phone connecting with my mini. It took less time than watching the video!

USE ANY PHONE WITH ANY COMPUTER

I concur to the idea of a webcam - also much easier to fix and position.

Also, unless you only use Apple ecosystem (re: Facetime), it may not be that easy or friendly to use the iPhone with non-Apple apps (skype, ms-teams, google meet, zoom…). For those (probably more chance to be used for work, school, more) it will be much easier with a logi webcam.

This depends on your model of Mac mini that you have, as well as what version of iOS and iPhone you have and version of MacOS that you have. There are versions of these that allow you to use your phone as your camera just by having them on the same AppleID. I have a Mac mini m2 and an iPhone 15 Pro Max and all versions are up to date with the most current and when I go into an app that uses a camera on my Mac mini I can select my iPhone 15 to be the camera for my Mac. I don't have to connect any wires or anything. As long as you have the hardware and the software to support it, you can do what your looking to do.

Is there anyway I can connect it to the Mac?

Just plug the webcam into one of the Mac Mini's USB ports. Works exactly the same way as on Windows.

That is how people lose fingers on their right hand… 😉

This article describes how to use your iPhone as a webcam.

That depends on your model of Mac Mini, macOS version it is running, your iPhone's model and iOS version.

Not me . . . it's perfectly safe and legal in England as you can see from this video shot in my crypt.
