How to design Video Surveillance System. Part 2: EN62676-4, Recognition, identification, PPM, PPF

Part2: Detection, Observation, Recognition, Identification (DORI) zones in video surveillance system design. Practical usage of pixel density defined by Part 4 of EN standard (IEC) 62676 "Video surveillance systems for use in security applications". Standard's mm per pixel for each operator task (Identification/Recognition/Observation/Detection/Monitoring) from the EU/IEC standard are converted to more popular untis: Pixels per Meter (PPM) and Pixels per Foot (PPF).
