I must protest. There is no way that they're building this with anything but municipal public-safety networking capabilities in mind. No off-the-shelf software from Aruba is aimed at citywide location-tracking capabilities. You could write one, or you could sort of hack away with a tool not designed for the job, but if you're really going for surveillance you'd focus on getting better tooling. So instead, they'll think of any tracking capabilities will be a handy added bonus. :) :(
