I am by no means an expert myself but I have installed a few and here is what I have found.......
Viper is the brand I have delt with most which is a division of Directed Electronics and they offer several options you can add to their systems that will help with your situation. Things like: glass sensors, equilibrium or roll sensors, door triggers, etc.
The best thing to do is go to an authorized dealer of the brand you want to buy and ask them about the features for your application. Even if you are not going to buy from them or have them install it they can answer your questions more directly than I can since they are schooled in that particular namebrand. Also, I have been out of it for bout 2 years now so no tellin what they offer now days.
