      Deep SORT combines simple online tracking with a deep association metric so detections can be
      linked into object tracks across video frames.

## TL;DR
AI for video surveillance uses computer vision to detect objects, track people or vehicles across frames, classify actions, and flag unusual events. The reliable public evidence is strongest for building blocks such as multi-object tracking, action recognition, and anomaly detection, not for broad claims about city-scale automation.

## Core Explanation
Video surveillance AI usually combines several tasks. Object detectors find people, vehicles, or other items in each frame. Tracking systems then connect detections over time so a system can follow the same object through a sequence. Action-recognition models classify clips into human activities, while anomaly-detection models look for segments that differ from normal surveillance footage. These methods can support review and triage, but their operational value depends on camera placement, data quality, governance, and human oversight.
