AbstractMost existing performance evaluation methods concentrate on defining various metrics over a wide range of conditions and generating standard benchmarking video sequences to examine the effectiveness of a video tracking system. It is a common practice to incorporate a robustness margin or factor into the system/algorithm design. However, these methods, deterministic approaches, often lead to overdesign, thus increasing costs, or underdesign, causing frequent system failures. In order to overcome the aforementioned limitations, we propose an alternative framework to analyze the physics of the failure process via the concept of reliability. In comparison with existing approaches where system performance is evaluated based on a given benchmarking sequence, the advantage of our proposed framework lies in that a unified and statistical index is used to evaluate the performance of an automated video surveillance system independent of input sequences. Meanwhile, based on our proposed framework, the uncertainty problem of a failure process caused by the system’s complexity, imprecise measurements of the relevant physical constants and variables, and the indeterminate nature of future events can be addressed accordingly.

Введено понятие эшелонной схемы построения коммутационного поля центрального узла систем IP-видеонаблюдения и выполнена соответствующая ей модернизация типовых принципов расположение образующего его оборудования. Обоснована возможность размещения оборудования центрального узла в 19-дюймовом шкафу шириной 600 мм при количестве телекамер вплоть до 480. Проведена оценка средней длины коммутационных шнуров и показано, что обращение к эшелонной схеме дает практически двукратное сокращение этого параметра, что улучшает условия администрирование системы. The concept of an echelon scheme for constructing the switching field of the central node of IP-video surveillance systems was introduced and the corresponding modernization of the standard principles of the arrangement of the equipment forming it was performed. The possibility of placing the equipment of the central unit in a 19-inch cabinet 600 mm wide with the number of cameras up to 480 was substantiated. The estimation of the average length of the patch cords was carried out and was shown that the use of the echelon scheme gave an almost double reduction of this parameter that improved the conditions for system administration.
