Icam for Android Huawei Camera -> Macbook OSX -> OBS

[msg_boi]

Hi there, I want to use my Huawei mate 10 pro Android phone as a webcam and connect it to my macbook which is running OS Sierra then into OBS software to live stream on twitch. 

I got a few questions
1) Which Android app do I purchase? Icam Pro or Icam?
2) Does it support 4k resolution?
3) Can I use USB to reduce latency and will it show up on OBS?

thanks in advance for all the help.

Our iCam application is meant to allow users to view their computer webcam remotely from their mobile device, as a sort of low-cost alternative to a security system. It is not meant to turn a mobile device into the equivalent of a USB webcam to connect to a computer.
