The report considers the reliability, accuracy and optimization of the technological equipment of a video surveillance system. Metrological reliability of the video surveillance system, determined by gradual failures is introduced, ie. by the probability that the relative error of the main system parameters is within the limits of the allowable values representing the function of the time for the technical operation. The metrological characteristics of measuring devices and video surveillance systems change during in the exploitation process. Practical studies and measurements in the operation of video surveillance systems show that metrological failures predominate significantly against nonmetrological ones. This fact demonstrates the need and the problem of optimization, improvement and development of special measures to predict and detect these metrological failures. The ability of measuring systems to maintain set values over a certain time interval, operating conditions and different process modes determines their metrological reliability. The report examines and analyses the types of failures in video surveillance systems, apparatus for determining the technical condition of measuring devices and the network is presented, research results are shown in order to optimize the operation of a video surveillance system. Means and methods for control equipment status are shown using a virtual spectral analyser and other appropriate equipment.
