I didn't even know some schools/universities had dedicated security (beyond doorkeepers checking IDs for certain buildings/nighttime security). Much less did I expect it's an ecosystem you could make money with. My university had 35k students and got by without such things. If something was amiss you'd call regular police. What sort of need does dedicated security address? I can see it for university buildings who store dangerous materials, but doorkeepers would address that just fine. I don't see why you'd have some sort of pseudo police force students would call with an app rather than calling the actual police.
