A dense AI camera network along the route the person walked, here 1,837 cameras across Hanoi, with footage searchable by appearance and direction of travel. A family report the same evening giving a starting point and a direction for the camera search. A ward police unit able to hand the search to the Traffic Police's camera-control team the same night.

- Relation to AI
-
The system's contribution was the trace. Police searched it in the direction the family gave. It returned images of the man walking along Nguyễn Tuân street toward Thanh Xuân Park and across other streets. That gave the police a route and pictures for a public appeal. A passing resident found him in Dịch Vọng about eleven hours after the report. No source says the finder had seen the appeal or that officers reached him. So the discovery itself is not attributable to the system. The vendor is not named and every account comes from the police.

Follow-up
- Conditions for replication
-
The missing person stays within camera coverage. Here the trace ended at a route, not at the man, and a passer-by made the find. Someone acts on the trace or the appeal. The sources do not establish that link in this case. The vendor and the matching method are undisclosed, so the trace cannot be checked beyond the police account.

People: A 78-year-old who had been out for nearly twelve hours on a December night was home by about 3 a.m. He was found hypoglycemic and close to fainting. He and his family got him back safely, though the finder was a passer-by rather than the police. Organizations: Thanh Xuân Ward Police and the Traffic Police got a direction of travel and images from the camera trace instead of a blind search. The police present the case as evidence of the new system's value.

- Purpose
-
Hanoi's AI traffic-camera system has 1,837 cameras with AI-controlled signals and was due to enter official operation in December 2025, per VOV. The Traffic Police run it, in VOV's words, “to ensure security and order and support the people” as well as to manage traffic. Tracing a lost resident for a ward police search falls within that stated remit.
