In modern surveillance systems speed domes are used often enough. The level of detail this camera can replace several dozen stand alone stationary cameras, allowing to distinguish between a person's face at a distance of 100 meters, but it requires constant operator control. Usually, these cameras are installed in patrol mode on fixed areas and occasionally in the manual mode. Also taking into attention the possible dishonesty of staff, the probability of capture an important event in close-up is very small. Even if in the surveillance system is established a large number of stationary cameras, their resolution does not always allows to produce acceptable recognition of a man.
