Marcello/Caprice, Love that you are adding 180VR. Since you asked for suggestions, currently the best kind of cameras are the ones used by CzechVR as well as other platforms like Amaze 3D (like Magga Braco). Suggest that you look at both of them for use, because they are really great at some things, though not others. For instance, most VR users love being able to get close to the model, so I am sure that the majority would love it if you were coming close to the camera and speak more.
Love the fact that we can talk to you both about it, and that you are asking for suggestions 🙂
