summary
Claims an open source prototype that uses CCTV-based distance estimation and simple microcontrollers to measure crowd spacing, send real‑time alerts and log temperature and vibration data for analytics. Describes an Android + cloud‑less beta and a web plugin, reports campus pilot tests (beta) with roughly hundreds of users and mixed results: camera placement and occlusion reduce accuracy, privacy needs password‑protected storage. Shows code components, Android/UI options and a planned data pipeline but admits the system is still experimental and only partially reliable.
