NetSnap, live camera feed, MJPEG stream, real-time snapshot, low-latency streaming, embedded vision, WebSocket. 1. Introduction Live camera feeds are central to modern IoT, security, and telepresence systems. However, many existing solutions suffer from a fundamental trade-off: continuous streaming protocols (e.g., RTSP, WebRTC) optimize for smooth video but introduce latency (often 2–10 seconds) and require complex client-side decoders. Conversely, simple HTTP snapshot polling yields low latency but lacks temporal continuity.
