A large standing crowd fills an open plaza in front of a modern glass building, watching an outdoor concert on a stage with large LED screens and lighting rigs at dusk. Across the four frames the crowd remains densely packed and mostly stationary, with many attendees holding up phones to record the performer shown on the screens.

Customer challenges
Scenic areas are large, but management staff are limited.
Water zones, trails, and outdoor areas carry higher safety risk.
Holiday crowds can build up rapidly in a short time.
There are many CCTV cameras, but events are still only known once someone watches the footage.
Restrooms and public facilities can see queuing, loitering, and falls.
Attractions are scattered, so managers lack a complete whole-site view.
Many incidents are only reviewed on video after the fact, with no proactive early warning.
Traditional smart tourism emphasizes people-flow counting and rarely truly understands what visitors are doing.
Customer benefits
