Welcome to Air Forums, if I haven't said it already on a different thread.
First question -- how and where do you envision using your Interstate? Context is important in determining security needs.
Secondly, there are a couple of previous threads you might want to look at regarding security generally - these might help you to generate more targeted questions.
I will say that the technology is still not where it needs to be for those of us who want home-like security systems in our vans. Car-like systems are readily available in the market, of course.

Comprehensive DVR and security camera system
Interstate security plates and dead locks
