A surveillance system is disclosed for preventing violence which may occur during attempts of armed robberies or acts of terrorism, thereby improving the security of persons within public buildings, governmental and industrial facilities. The system utilizes one or more optical imaging device(s) strategically located throughout the facility under surveillance, and in particular the entry ways therein for detecting potentially armed individuals or intruders entering or moving about the facility. The optical imaging devices operate in conjunction with a computor system having one or more databases containing information indicative of the presence of weapons and representing the types thereof which may be brandished by one or more persons entering the area under surveillance, and data indicative of the spectrum of human pre-aggressive movements, postures and gestures. The databases enable the system to differentiate between law enforcement personnel and their weapons from potential intruders and their weapons. The system includes immobilizing projectile firing devices, and is devised to tract the armed intruders, to target the intruders for possible immobilization, and to collect and maintain video evidence and other recordings of the results of such detection and tracting for possible legal evidenciary use.
