Security-Camera-Agent

Camera agent for Raspberry Pi Zero 2W security cameras ARCHITECTURE OVERVIEW ┌─────────────────────────────────────────────────────────────┐ │ MULTI-CAMERA SYSTEM ARCHITECTURE │ │ (5 Threads Active) │ └─────────────────────────────────────────────────────────────┘

Thread 1: Circular Buffer (Camera) └─► Captures H.264 video continuously └─► Feeds to Thread 2 and Thread 3

Thread 2: Motion Detector └─► Monitors for motion └─► Creates events via API └─► Signals Thread 3

Thread 3: Event Processor └─► Saves pictures and video └─► Creates sentinel files (.READY) └─► Triggers Thread 5

Thread 4: MJPEG Server (Future) └─► Will provide live streaming

Thread 5: Transfer Manager ⭐ NEW! └─► Monitors for sentinels └─► Transfers files to NFS └─► Notifies central server API └─► Cleans up local files

Result: Fully autonomous camera system! 🎉
