Changnyeong County Completes Korea's First System for Automatically Displaying Detected Events, Protecting Residents 365 Days a Year

AI-Powered Monitoring with No Blind Spots
Smart Monitoring Transforms Safety Administration

The Video Information Integrated Control Center in Changnyeong County, South Gyeongsang Province, has achieved its best results since opening in 2015, completing the upgrade of AI-based smart monitoring and field-centered work processes to help protect residents’ safety.

Through 2025, 16 monitoring operators at the Changnyeong County Video Information Integrated Control Center worked in four teams on a three-shift rotation, monitoring approximately 1,515 CCTV cameras across the county in real time, around the clock, and maintaining the front line of local safety.

However, the existing smart monitoring system for intelligent CCTV, introduced in 2019, had low accuracy in detecting unusual behavior by people and other subjects, and frequently generated false alarms due to animal movements, weather conditions and other factors.

In addition, as each monitoring operator was responsible for more than 300 CCTV cameras, the real-time sequential monitoring approach continued to face structural limitations, including blind spots, differences in monitoring quality between areas, and increased work fatigue.

To address these issues, the county built a new integrated monitoring work management system, replaced outdated monitoring equipment, and overhauled its smart monitoring approach. It also became the first in the country to complete a system that automatically displays detected events on screen.

Under this system, when AI detects unusual behavior by a person or other subject, the relevant video is automatically prioritized and displayed on monitoring operators’ screens. This has significantly reduced time spent on unnecessary routine monitoring and increased monitoring efficiency by more than tenfold compared with the previous system.

The effects of the new monitoring approach became immediately evident in the field. In March and July, smart monitoring detected fires in townships and town areas before they spread, enabling fire engines to reach the scenes within 10 minutes and extinguish the fires at an early stage.

In April and July, the system detected suspicious behavior, including wandering and stopping, by people suspected of being at risk of suicide near Namji Bridge and at reservoirs in the county. Police arrived at the scenes within five minutes and rescued them safely. During the recent Chuseok holiday, the system also spotted a suspicious man wandering around a traditional market, helping police quickly apprehend a theft suspect they had been tracking for several days.

By establishing a system for rapidly sharing information with relevant agencies through smart monitoring, the center has more than doubled its year-on-year record of initial responses to major incidents and accidents and securing critical response time. It has clearly demonstrated its role as a “safety control tower” that protects residents’ precious lives and property.

To support these efforts, the county upgraded its internal monitoring system and improved the maintenance of field facilities by introducing a mobile fieldwork system and expanding infrastructure tailored to on-site needs.

Introduced in June, the “CCTV Mobile Fieldwork System” has replaced inspection methods that previously relied on paperwork or handwritten records. Staff can now use smartphones at the scene to immediately inspect and address faults, and report and register the results in real time. This has significantly shortened CCTV repair times and established a foundation for systematic asset management.

The county also carried out a project to expand infrastructure tailored to on-site needs. This year, it completed the installation of new security and intelligent CCTV cameras at 25 locations across the county and replaced outdated equipment at 20 locations.

In particular, the county further strengthened its close-monitoring system using smart monitoring by installing additional intelligent CCTV cameras and automatic warning speakers near Namji Bridge, where there is a high risk of safety incidents such as people jumping from the bridge.

The county also installed solar-powered cube-shaped LED signs in monitoring blind spots and crime-prone areas to prevent nighttime crime and raise public awareness, helping residents feel safer when walking at night.

Recognized for its outstanding proactive safety administration through improvements to its monitoring system using AI, the center received an Excellence Award at the 15th Korea Knowledge Awards, hosted by the Ministry of the Interior and Safety. This achievement enhanced Changnyeong’s brand value as a “smart safety city” and presented an exemplary model of knowledge-based administration for local governments across the country to follow.

A county official said, “We will not rest on these achievements. We plan to additionally build an AI-based system to track missing persons in real time and continue upgrading our real-time cooperation system with relevant agencies. We will continue to actively introduce AI technology into public administration and do our utmost to make Changnyeong a smart safety city where all residents can live with peace of mind.”

With the completion of the system that automatically displays detected events at the Changnyeong County Video Information Integrated Control Center, monitoring efficiency has been maximized. The improvements are expected to help residents live more safely and comfortably through faster initial responses to incidents and accidents, better access to critical response time, and an increased sense of safety at night.
