Detector comparison — adopt → adapt → AI-native

synthetic, or a public clip under the safe root e.g. /data/vtest.avi (needs ALLOW_EXTERNAL_SOURCE=1; public/synthetic only, no CCTV). Real footage is auto-blurred for privacy.

Source: vtest.avi · max_frames 80 · advanced detectors: ENABLED · backend yolo · privacy blur: ON

Motion = movement (any change). HOG/YOLO = people detectors. On the synthetic blob scene people-detectors correctly find ~0 persons; use a public pedestrian clip (e.g. vtest.avi) to see them work.
