Anyways, automation would free up more budget for people and automated solutions focused solely on safety. I can't imagine it'd be that hard to devise a solution that lets few employees observe most of the stations and then trigger some sort of lockdown where a mugging occurs. The computer vision heuristics for focusing the attention of a CCTV monitoring station could probably consider things like:
(1) Show locations with a sparse number of people occupying the space.
(2) Based on walking gait over time, cluster humans together as related (Two people walking together side by side are probably together)
(3) Place importance on humans walking alone
(4) Place importance on humans walking alone that are about to "intercept" another human walking alone.
(5) Use head and eye position and gait speed changes to determine intent to intercept by assuming a gaze heuristic is being used by the mugger.
An operating watching the live videos with focus would then make a call of whether of not a mugging has occurred or probably has occurred. They would then dispatch an image of the mugger and muggee directly to the phones of a the nearest officer or two that can investigate. The system would tracker the mugger and muggee across several video feeds.
These are just a few ideas on how greater safety can be fully automated.
