About the project
The project is a distributed Smart City video-surveillance platform for edge devices. It includes a central controller and multiple edge workers responsible for camera management, storage, and event processing. The platform handles RTSP→HLS video conversion, integrates with S3 storage, and uses an event-driven architecture based on NATS JetStream. Deployed across several countries, the solution focuses on scalability, observability, and reliability.
