async function takeSnapshot() const response = await fetch('/snapshot?sync=true&last_frame=' + lastFrameId); const jpegBlob = await response.blob(); // save or display snapshot

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.
