Does anyone know the specs on the passthough camera system? FOV, etc...

I'm working on an AR app, and I'm currently prototyping on an Oculus Quest.  

Since we don't have access to the passhrough camera system, I was thinking that I can find a small camera with the same specifications to mount on the front of the unit and video edit the video captured between the new camera and in-game play footage, in order to get a feel for some AR mechanics I'd like to visualize.

Does anyone know any information on the passthough camera that would help me pick out the proper camera to use?

Thank you in advance for any help.
cheers)
