Block iPad interactions for exhibition

[Usikava]

Hi there.
I have a special need of sort. I'm working in a museum of modern art and one of the works is to be shown using iPads, my goal is to block any actions from visitors like closing application or opening other applications or even shuting it down (yeah we could make a case to block interaction with buttons but it won't solve the whole case).
So i want it to stand and display the only one(or several) video file so no one could do anything with it until the full reset or at least until they will enter password.

Maybe using Guided Access will help:
