Sub-stream at 640x360 produced low quality snapshots and poor LPR accuracy. Switched detect to main stream 1920x1080 at 2fps (VAAPI handles decoding). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Dual-stream config (sub for detect, main for live/snapshots), Intel VAAPI hardware accel, LPR local (YOLOv9 + PaddleOCR), car/person detection, snapshots 30j retention. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
