Precision is the fraction of positive predictions that turn out correct: TP / (TP + FP). High precision means few false alarms. In CCTV analytics low precision is operationally toxic — alarm fatigue trains supervisors to ignore alerts within a week. FI Tech holds precision above 0.90 across PPE classes through hard-negative mining: we feed the model lookalike clutter (orange traffic cones mistaken for vests, water bottles misread as gloves) until the false-positive rate drops below the contractual ceiling. Precision and recall always trade off; F1 score balances them.
