Studied in this paper is an advanced detection system which activates emergency alert system to prevent the actual incidence, after computerized evaluation of danger-associated behavior captured in CCTV images. The detection of potential danger involves the ability to discern several steps that may ultimately lead to life-threatening event of an object. The system is designed with preset danger-zone within the zone of interest and analysis of blob composition, based on the assumption that probability of life-threatening event is directly correlated with the proportion of one overlapping with the danger zone. Subsequently, the danger level is evaluated accordingly to the range of encroachment into the danger zone of the targeted objects.
