Dahua showcases AIoT tools for safer and more efficient cities
Dahua Technology presented a range of AIoT solutions for urban safety, traffic, public transport, city management and environmental monitoring at Smart City Expo World Congress 2026 in Barcelona. The company said its systems are designed to help cities become safer, more efficient and more sustainable.
- Dahua presented AIoT solutions at SCEWC 2026 in Barcelona.
- Its traffic project in Campeche covered 34 intersections and seven green waves.
- The company reported a twenty percent increase in traffic volume and a fifteen percent reduction in waiting time.
- Thermal imaging systems can detect potential fire sources up to ten kilometres away.
- Dahua highlighted privacy, transparency and accountability in AI-powered city management.
AIoT applications across city operations
Dahua said its urban safety solutions connect cameras and other IoT devices with AI-based analysis to identify risks and coordinate emergency responses. One application combines intelligent recognition, text and image search, and route tracking with connected broadcasting and security workflows to support searches for missing people.
For traffic management, the company presented tools for traffic monitoring, signal optimisation, enforcement and incident detection. In Campeche, Mexico, Dahua optimised 34 intersections and introduced seven green waves. According to the company, the project produced 23 improvements, increased traffic volume by twenty percent and reduced waiting time by fifteen percent.
Dahua also demonstrated smart mobility systems for public transport. These include vehicle monitoring, safety alerts and integrated information. In bus operations, driver monitoring can detect risky behaviour, while real-time video, GPS tracking and passenger counting support safety oversight, fleet management and fare control.
Monitoring public spaces and the environment
The company's city governance technologies use AI analysis and multimodal information processing to detect issues including illegal street vending, waste in public spaces, missing manhole covers, flooding on roads, blocked fire lanes, smoke and fires. Natural-language search and automatic alerts are intended to help city employees identify problems and coordinate responses.
Dahua also presented environmental solutions for protecting natural resources and managing environmental risks. High-mounted thermal imaging cameras provide 360° coverage and can detect potential fire sources up to ten kilometres away. The cameras work with ground monitoring and drones to support fire detection and emergency response.
For water monitoring, a radar system is combined with a PTZ camera to track water levels in real time. The system can send alerts when measurements exceed preset thresholds.
Dahua links AI deployment to responsible governance
John Li, General Manager of the Global Government Business Department at Dahua Technology, joined the high-level roundtable “Agentic AI: Systems That Act.” He discussed how AI integrated into cameras and sensors could support proactive city management, including AI-powered searches and AI agents that identify urban problems and track their resolution.
Li also stressed the importance of privacy, transparency and accountability in ensuring that AI delivers social value. In a separate discussion, “Building Resilient, Inclusive & Sustainable Smart Cities with AIoT,” Max Huang, Director of Global Government Projects at Dahua Technology, described edge intelligence and high-quality structured data as foundations for applying large AI models in practical smart-city settings.
The event took place in Barcelona from 3 to 5 November 2026. Dahua said it will continue working with customers and partners to develop smart-city solutions and support the ongoing digital transformation of cities. For users and city authorities, the announcement points to a model in which cameras, sensors, analytics and automated alerts are combined across transport, public safety and environmental services, while the company’s own speakers emphasise the need for responsible deployment.
