Single-camera tracking vs cross-camera re-identification, the honest accuracy metrics (MOTA/IDF1/HOTA, the single-to-cross-camera drop, never 100%), how a track surfaces via ONVIF Profile M (the per-device ObjectId caveat), where it runs (edge vs server/cloud), and the privacy line (a movement trail is personal data; face/gait is biometric) — on one page.

Fora Soft Video Engineering Handbook
This object tracking and re-identification reference separates single-camera tracking from cross-camera re-ID, with MOTA, IDF1 and HOTA, edge versus server placement and the privacy line. Our seven-volume handbook covers the video stack; start with Volume 6 on detection, tracking and computer vision, then Volume 7 on real-time pipelines and biometric regulation, with Volume 1 for encoding. Written by Nikolay Sapunov, CEO at Fora Soft.
