Don’t worry, that’s probably one of the real reasons for 100 camera systems. As someone else pointed out, you don’t need 100 cameras to act as a policy enforcement and deterrence, but if you wanted to get constant surveillance of vehicles and people movements, recorded in public, you would want 100+ systems.

You can’t (currently) ticket people for crimes like speeding, but you can use it to ticket for other non-criminal violations like other parking violations, i.e., replacing meter maids.
