Abstract

The paper presents the results of determining the areas of application of a laboratory stand designed for studying and researching CCTV systems. The necessity of research of video cameras of the security alarm system, their testing at the organization of production and expediency of carrying out laboratory works by students of higher education institutions studying security systems is shown. The state of affairs in this area in post-Soviet countries is shown. Some requirements of the State educational standard on informativeness and expansion of opportunities of laboratory stands are given. The input parameters necessary for the design of video camera research stands are considered. The results of the study of the developed laboratory stand for the study and study of security television systems and the definition of areas for its application are presented. The structure of the stand and its parts is proposed. Developed recommendations for its use are given. The experience of conducting laboratory work on the study of the characteristics of security alarm cameras is analyzed. The possibility of studying robust filtering on the noise immunity of the video system, the influence of the illumination spectrum on the main qualitative characteristics of the video camera using the proposed stand is shown. A list of suggested to run the stand includes laboratory work “Studying the parameters, operation modes and configuration of video surveillance system NOVUS”, “the Study of possibilities of various types of cameras when changing the light and characterization of the sensitivity of various types of cameras, Definition of focal length, angle of view and resolution of different types of cameras and lenses, Definition of the working area of observation, the far and the dead zone for various types of cameras and lenses”, "Determination of conditionally dead zones for different recording speeds of the DVR and at different focal lengths” and" Determination of the volume and quality of recorded information from the value of the recording speed of the DVR”, as well as research works “The signal processing with variable spectrum”, “the Influence of robust filtering for noise immunity video”, “Influence of illumination spectrum on the main qualitative characteristics of the camera” and “Comparative performance of analog and digital cameras.”
