• Liaoyuan's demands for building a high-quality smart city, covering multiple sectors, including city management, emergency command, public security, and health care. • Unable to connect different functional sectors for lack of a unified information system; without IoT, city management is restricted to manual intervention.

• The non-smart legacy surveillance platform lacks video processing capability, resulting in unclear images and low work efficiency • The existing information systems are isolated, making it difficult to centrally manage video surveillance products and achieve multi-platform interconnection and collaboration. As a result, intelligent analysis of massive data and effective data mining are impeded.
