DEFINING THE APPLICATION FIELDS OF THE STAND FOR INVESTIGATING THE VIDEO MONITORING SYSTEMS

Abstract

The necessity of researching video cameras of security alarm systems, their testing in the organization of production, and the feasibility of carrying out laboratory work by students of universities studying security systems are substantiated. The state of affairs in this area in post- Soviet countries is shown. Some of the requirements of the State Educational Standard for informativeness and the expansion of the capabilities of laboratory stands are given. The pa- rameters necessary for the design of stands for the video cameras research are considered. The results of the study of the developed laboratory stand for the study and research of security television systems and the identification of areas for its use are presented. The structure of the stand and its parts is proposed. The developed recommendations for its use are given. The ex- perience of the laboratory work on the study of the characteristics of security alarm cameras is analyzed. The possibility of studying the robust filtering for video noise immunity, the influ- ence of the illumination spectrum on the main quality characteristics of a video camera using the proposed stand is shown. The given list of works proposed for performance at the stand includes laboratory works “Study of parameters, modes of operation and configuration of the NOVUS video surveillance system”, "Research of capabilities of various types of video camer- as when changing light and determining the sensitivity characteristics of various types of video cameras ”, “Determination of focal length, viewing angle and resolution of various types of cameras and lenses”, “Determination of the working observation area, the far and dead zones for various types of cameras and lenses”, “Definition of conditionally dead zones for different recording speeds of the DVR and at different focal lengths” and “Determining the volume and quality of recorded information from the value of the recording speed of the DVR”, as well as the research works “A device for processing signals with a changing spectrum”, “Influence of robust filtering on video noise immunity”, “Influence of the backlight spectrum on the main quality characteristics of a video camera” and “Comparative characteristics of analog and digi- tal video cameras”.
