Report: CCTV Analyzes Stalker Behavior and Alerts Police... How AI Is Transforming Public Safety

#. When a stalker appeared in front of Mr. A’s house, the Intelligent CCTV detected Mr. B. The device sent alerts to Mr. A’s issued smartwatch and to the administrator’s smartphone. The 112 emergency call center also received a report of Mr. B’s suspicious behavior. Thanks to this, the police were able to respond quickly.The Intelligent CCTV is one of the Artificial Intelligence (AI)-powered devices showcased at the 7th Korea Police World Expo (KPEX) on the 22nd. The AI determines whether a stalker is merely loitering in front of a house, exhibiting abnormal behavior, or attempting to trespass, and responds accordingly. If the situation is deemed urgent, an automatic alert is sent to the responsible police officer. If there is no direct action, only the victim receives a notification. The decision to report to the police is left to the victim. Security company KT Telecop, CCTV manufacturer JWC, and Fine Digital are installing these devices at the residences of victims at the request of the police.
This exhibition, hosted by the Korean National Police Agency (KNPA) in Songdo, Incheon for four days starting today, presents a variety of ways that future industries such as AI can be utilized in public safety.
A program that assists in analyzing financial transaction data received from other institutions also stood out. Using this system, investigators can review data from various institutions—each with different formats—at once. After uploading data from banks, securities, credit card, and telecommunications companies, investigators can select and visualize only the necessary information. This allows for intuitive tracking of financial transactions between suspects. Through AI learning based on investigative data, a standardized algorithm has been developed. Noah Ventures, under a research and development contract from the Ministry of Science and ICT (MSIT) and the KNPA, has been developing this program since 2023 over a three-year period. Once introduced in the field next year, it is expected to reduce investigators’ workloads. A company representative stated, “Because we continuously add new data for training, the accuracy is close to 100 percent.”
Other AI-based public safety technologies expected to transform police work and citizens’ lives include child abuse video detection software (ZIOVISION), autonomous patrol robot systems (Pusan National University, PNU), and voice phishing detection (KT).
A total of 216 domestic and international companies, including AI firms, are participating in this year’s exhibition. To support practical market entry, the event features equipment evaluation sessions with added technology verification, cybersecurity system purchase consultations, public procurement meetings, and one-on-one export consultations. In celebration of the 80th anniversary of the police force, citizen participation events such as police uniform improvement experiences, smart shooting simulations, and patrol car and drone demonstrations are also being held.
