VIVOTEK and Chengli Deploy Smart Video Surveillance System on Danjiang Bridge
Smart operations · Water and transportation engineering
VIVOTEK partnered with system integrator Chengli International to deploy 40 specialized cameras with AI video analytics on Danjiang Bridge. The system supports 24/7 monitoring, vehicle classification, traffic threshold alerts, and historical video review for the bridge control center.
To meet operational and traffic management demands for Danjiang Bridge over the Tamsui River estuary, VIVOTEK partnered with system integrator Chengli International to deploy an intelligent video surveillance architecture. As the world's longest span asymmetric single-tower cable-stayed bridge, Danjiang Bridge accommodates mixed transit modes, including automobiles, motorcycles, buses, bicycles, and pedestrians. The project deployed 40 specialized cameras, using weather-resistant PTZ speed domes as the primary backbone alongside bullet cameras and license plate recognition units to withstand coastal salt spray and wind. The system integrates AI video analytics to enable real-time traffic threshold alerts, vehicle classification, pedestrian counting, license plate recognition, and post-event video query using new rule sets, supporting the dedicated traffic control center with exportable CSV reports for signal optimization and incident management.
Key takeaways
- VIVOTEK and Chengli International deployed 40 cameras across Danjiang Bridge, using weather-resistant PTZ domes and license plate recognition units for blind-spot-free coverage.
- The system incorporates AI analytics to support real-time traffic threshold alerts, historical footage re-querying, and vehicle classification.
- The deployment integrates pedestrian counting and license plate recognition, exporting CSV reports to aid signal timing optimization.
