VIVOTEK and Orange Power Deploy Smart Video Surveillance for Danjiang Bridge Traffic Control

VIVOTEK partnered with system integrator Orange Power to implement a smart surveillance framework for Taiwan's Danjiang Bridge. Spanning the Tamsui River estuary with a main span of nearly one kilometer, the asymmetric single-tower cable-stayed bridge features a dedicated bridge traffic control center operating 24/7. To withstand harsh coastal winds, salt spray, and low-light conditions, 40 weather-resistant cameras—including high-resolution PTZ domes, bullet cameras, and license plate recognition units—were deployed along the structure. The installation integrates AI-driven video analytics supporting real-time monitoring alerts and retroactive historical footage retrieval. The analytics engine classifies and counts vehicles such as cars, trucks, buses, motorcycles, and bicycles, while distinguishing pedestrians from individuals wheeling or riding bikes. Traffic managers can configure custom flow thresholds for automated alerts, utilize integrated license plate recognition (LPR), and export traffic datasets into CSV format for signal timing optimization and traffic management decisions.

Key takeaways

• VIVOTEK and Orange Power deployed 40 specialized cameras, including PTZ domes and LPR units, along Danjiang Bridge.
• The system incorporates AI video analytics for vehicle classification, pedestrian counting, LPR, and retrospective footage review.
• Traffic control operators can set custom volume thresholds for automated alerts and export operational data to CSV reports.
