Created a Game for an Experiment. Is it possible to have an off screen camera recording the game?

I created a game, where you have a first person point of view and you need to walk around a small space and find a hidden box. I am using software to record the person’s play time, but through the first person perspective make coding and recording data very hard. So is there someway to get an overview of the whole arena(pretty small) and record it without letting the other person know?

You can have another camera positioned anywhere and rendering to a render texture. You should be able to do a search to find ways of saving the frames to a movie file.

Alternatively, make the game multiplayer and have another computer player somewhere. Point that camera where you want and use fraps or something to record the screen.
