Continuity camera won't connect wirelessly to iPhone, works fine when connected with cable

This starts to sound like some Third Party Application(s) installed on the computer is reaking havoc with the Normal Operations of the computer

Any of the below come to mind ?

Any Third Party Applications that will interfere with the normal operation of the OS,  is an invitation for disaster and comprising the Operating System

Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a portion on each sale. What the Application may do to the computer is up to the User to check this out before purchase

Hello discussed,

Thank you for posting in Apple Support Communities.

You will need to ensure you are using an iPhone compatible mount or stand. Also, you will want to ensure the phone is: 

·       Near your Mac

·       Locked

·       Stable

·       Positioned with its rear cameras facing you and unobstructed  

·       In landscape orientation to allow apps to choose your iPhone automatically, or in portrait orientation

If all of that is met, Open FaceTime or another app to use with your iPhone camera. If the app doesn't automatically begin using it, choose your iPhone from the app's video menu, camera menu, or other setting. For example, in FaceTime your iPhone camera is available from the Video menu.

Kindest regards. 

I've successfully setup the Continuity Camera feature on a Mac mini (2018) running Ventura 13.0.1 and an iPhone XS Max running iOS 16.1.1.

MacOS will notice the iPhone (if a number of requirements are met) and prompt the user to confirm that they want to setup the feature. In my experience, this takes a bit of time. Also, it helps if the iPhone is kept in landscape mode and is stable.

I've used the iPhone as a webcam (both video and audio) with QuickTime and with Zoom.

You should see the popup below in order to enable the feature.

One site suggests the following advice (from Apple's documentation).

... macOS Ventura apps are able to detect iPhone camera for the Continuity feature only when the following conditions are met:

• • iPhone is standing still in landscape mode.
  • Screen is turned off.
  • Device is locked.

Since you've already verified, I'm not sure why your experience is different from my own.
