The results of the analysis of the functional completeness of ten intelligent video Analytics systems are presented. It is shown how the video Analytics systems selected for comparison have similarities or differences in the criterion of functional completeness. The paper analyzes whether they contain the most typical video detectors and what additional video Analytics functions each of the compared systems has. It is shown how it is possible to estimate as far as functional completeness of this or that system corresponds to requirements of the user.

Keywords: intelligent video surveillance, video Analytics, specialized videodetector, intelligent analysis of video analysis of functional completeness, a formal analysis of the degree of similarity systems, a measure of similarity of Jacquard, Earl of superiority,

This article presents a mathematical model of the distributed registry as a Queuing network. The main components of this network, as well as their formal representation are considered. The model of the peer-to-peer network is visualized, the vector of the network state is defined, and the restrictions of the state space are defined. After that, the laws of distribution of individual flows and service time were presented. In addition, the design elements of the infinitesimal matrix were determined. Based on the data obtained, a simulation model of this process was produced. For simulation, the Anylogic package was used. The results of simulation were analyzed and the most optimal parameters were selected.
