Does anyone know if this works? I have install an app called iVCam on my phone and PC and they seem to be working. I can see the video output from the phone on my PC just fine. However when I I go to the test webcam link I do not see anything in the Video or Audio drop-downs. Any assistance would be great. Thanks

I'm having the same issue. Did you ever work out the solution?

I'm using old iPhone as webcam with Kinoni Epoccam app (free version so far). https://www.kinoni.com/support-and-instructions/

 iPhone and laptop need to be in same WiFi network. Otherwise easy to install, easy to use.
