Ricoh theta Z1 placement

Hi, I have two Ricoh Theta Z1 cameras that I want to use for educational purposes. First of all, I want to check which settings are best for recording and adding interactivity to the video. For example, where should I place the camera, what should the resolution be, and what should the lighting conditions be (should I turn the lights in my room on or off)?

The dimensions of my room are not equal, so I cannot place the camera in the center. There are also other objects in the room, like 3 to 4 tables of different sizes. Can anyone recommend what I should do and where I should start? Apart from Unity, what other tools can I use to add hotspots in the video and incorporate some game mechanics?
