Approach to Implementation of Transport and Physical Levels of Distributed Computer Vision System

The option of construction of physical and transport levels of the system of distributed computer vision system with application of intermediate PoE-switch is considered. The possibility of achievement of the branching ratio equal to 3 in case of using the Class I terminal technique is shown. It is proved that it is possible to increase the length of the cable channel up to 350 m using the PoE technique and using 600 mPoE+ technique with the use of class 1 TV cameras with the power, not exceeding 3 W. It is established that effective means of increasing the length of the channel are cables with an increased diameter of the twisted pair insulation electric copper conductor.
