Video Surveillance systems involve sophisticated technology. Features include night vision, computer assisted operation, and motion detection facilities which allow the operator to instruct the system to go on red alert when anything moves in view of the cameras. Camera systems increasingly employ bullet-proof casing, and automated self defense mechanisms. The clarity of the pictures is usually excellent, with many systems being able to read a cigarette packet at a hundred meters. The systems can often work in pitch blackness, bringing images up to daylight level.
The technology is ultimately converge with sophisticated Video Data Intelligence programs that are capable of automated Facial recognition, Behavioral Characteristics, crowd behavior analysis, and (in certain environments) intimate scanning of the area between skin surface and clothes. The power and capabilities of cameras will continually increase, while the cost and size will decrease.
Video Surveillance is reasonable to assume that covert visual surveillance will in some environments be ubiquitous.
