The paradigm bridges this gap: a persistent server that provides a live MJPEG stream for visual awareness while offering instant, high-quality snapshot capture triggered by client or event-based requests. This paper focuses on the “live cam-server feed” component — the backend service that captures, encodes, and distributes camera frames in near real-time.
