November 12, 2025 / Barcelona, Spain. For the second time, Dahua Technology, a world-leading video-centric AIoT solution and service provider, has successfully showcased its cutting-edge smart city solutions at the recently concluded Smart City Expo World Congress (SCEWC) in Barcelona, Spain.
As the world’s biggest and most influential event on urban innovation, this year’s SCEWC 2025 has brought together experts, innovators, and city leaders from around the globe to explore the future of urban transformation. Dahua’s comprehensive lineup of smart city solutions related to urban safety, urban traffic management, city governance, green mobility, nature protection, ecosystem cooperation and large-scale model technologies have taken the spotlight, demonstrating how advanced AI, IoT, and big data technologies are driving more sustainable, efficient urban environments.
Urban Safety Solution: Monitoring Security via City Operation Center
Improving urban safety is the core goal of smart cities. The Urban Safety Solution of Dahua offers a city operation center that can monitor and analyze the real-time operation status of the city, including public safety, transportation operation status, environmental index, etc. It can integrate various AIoT sensing devices through a unified platform, including cameras, radars, traffic flow cameras, and other sub systems such as traffic signal control systems, urban weather systems, and alarm systems. Various solutions for intelligent police cars and bodycams are also available to help improve the efficiency of police patrols and detect abnormal situations immediately. Additionally, 6 capability centers are developed in order to build the city operation center: General Business Enabling Center, Intelligent Operation Center, Full Connection Center, Big Data Center, Intelligent Computing Center, and City Command Center.
Urban Traffic Management Solution: Enabling Full-chain Event Detection
Dahua also featured its Urban Traffic Management Solution that focuses on signal control, traffic enforcement and highway operations. To solve urban congestion issues, Dahua’s Signal Control Solution can dynamically adjust signal control schemes and evaluates urban traffic performance based on real-time flow of data. For traffic enforcement, Spotter Mobile enables flexible and mobile enforcement while Spotter Ultra (Dahua’s flagship speed enforcement product) supports wider coverage of up to 8 lanes without the need for additional gantry, reducing overall construction costs. For highway operations, Dahua's event detection capability covers over 30 types of traffic incidents, such as stopped vehicles, wrong-way driving, and over speeding.

Transportation Solution: Promoting Green Mobility
Dahua’s Transportation Solution provides fuel consumption detection, dashcam, cargo safety detection system and volume monitoring system. It features Bus Solution that offers various intelligent functions such as active safety, passenger counting, and general video surveillance. It also includes cameras with Dahua’s BSIS (Blind Spot Information System) that can solve blind spot issues while meeting EU general safety regulations (R 151).
City Governance: Implementing Intelligent Multi-modal Urban Monitoring
In order to enhance city governance, Dahua built an intelligent, multi-modal framework (Urban Management Module, Emergency Response Module, Environment Monitoring Module and Safety Supervision Module) that connects people and systems through texts, voices, and images. It enables intelligent features such as: Image-Text Search that fuses image and text information for natural language–based video and image retrieval; Intelligent Interaction that integrates large language models for conversational task scheduling and context-aware reasoning; and One-Stop Linked Operation that connects knowledge bases, and third-party systems, providing a unified portal for alarm viewing, video access, collaboration, and task assignment.
Nature Protection: Protecting the Environment through Technology
Dahua also showcased its Natural Resource Protection Solution that focuses on four key areas: forest protection, hydrological affairs, land supervision, and biodiversity protection. Dahua’s Forest Fire Prevention Solution, for example, establishes a closed-loop system that enables multi-dimensional sensing, intelligent analysis, and precise command, greatly enhancing early warning, rapid response, and scientific decision-making in forest fire management. The Fire Prevention Solution focuses on preventing human-caused wildfires through a three-layer defense system (access control, warning posts, and perimeter monitoring). The Fire Detection and Location Solution combines thermal imaging monitoring with an intelligent IoT platform to achieve early detection, warning, and rapid response. The Real-Time Wildfire Sensing Solution leverages drones as the key tool to enable dynamic fire monitoring and rapid emergency response.

Ecosystem Cooperation: Empowering Partnership & Collaboration
Also highlighted in the exhibition is Dahua’s growing ecosystem cooperation with its partners and clients. Dahua ECO Partner Program (DEPP) and DoLynk Developer accelerate collaboration and innovation across global ecosystems. DEPP is an open platform for global technology innovators that brings together 175+ partners across six continents. DoLynk Developer, Dahua’s cloud-based open platform for AIoT innovation, seamlessly integrates video, alarms, and incident management while offering APIs and SDKs for partners to build custom applications.
AI Powered Technology: Introducing the Xinghan Large-Scale AI Models
Among the main highlights of Dahua’s smart city solutions is the Xinghan Large-Scale AI Models, which are industry-specific large models (with visual parsing at its core) that integrate multimodal capabilities and industry expertise. Consisting of V-Series (Vision Large Model), M-Series (Multimodal Large Model) and L-Series (Language Large Model), Xinghan provides rich benefits including higher accuracy, high generalization capability, complex behavior recognition, and more. It can help transform smart cities from reactive surveillance networks into proactive, adaptive urban intelligence systems, thus improving safety, mobility, energy efficiency, and citizen services through deeper visual understanding.

During the event, Dahua was also cordially invited to speak in a series of panel discussions together with other distinguished guests and experts in the industry. Mr. John Li, General Manager of Government Business Department at Dahua Technology, proudly represented the company in an informative discussion about GovTech and how digital tools can strengthen public services. “When cities go digital, it should be about giving people better services. At Dahua, we build every solution starting with empathy – focusing on people’s real needs, not just in technical details,” he explains. “At the end of the day, putting people first means technology works for us – not the other way around. How we measure success isn’t about impersonal numbers, but about making people’s quality of life better,” he added.

In addition, Mr. Max Huang, Project Director of Government Business at Dahua Technology also joined a panel of experts that tackles how Next-Gen Tech contributes to urban revolution. He said: “LLM (Large Language Model) makes our IoT system smarter. It understands the city very well. It enables the central data brain to think by itself, which can significantly help city governance. Utilizing LLM, we can truly make the city operation safer, more efficient, and more sustainable.”
