Advice on disciplinary action by university

Well people seem to be jumping to conclusions which perhaps is understandable as I didn't have the energy to write a full account from the start. My friend records lectures and revises using a camera about the size of a car key fob. He met someone online whom he was talking to about his course and saying he would be in the library a lot due to exam resits in the summer. He mentioned this camera and saying how it was really small like a spy camera to which this other guy said he could probably spy on things with it. That's how it started off.

Obviously I can understand how it looks on the surface but this is not a clear cut case of taking perverted pictures without consent. As I have said anyone looking at them would not have seen it that way. It was literally like if I was in say a shop and was walking around with my phone recording.
