Analog-digital combination based video monitoring system

Abstract

The invention discloses an analog-digital combination based video monitoring system, and belongs to the field of video monitoring. The analog-digital combination based video monitoring system comprises a video camera which is divided into four paths of analog video signals through a video distributor; the third path of analog video signals are connected with a video analysis device through a signal transmission conversion module; the fourth path of analog video signals are connected with a video coder through a signal transmission module; the video analysis device is connected with a central network server through a data signal transmission module; the video coder is connected with the central network server through the data signal transmission module; the central network server is connected with the video decoder through a wireless transmission way; and information interaction is carried out between the video decoder and a control display device through a signal transmission conversion module. By cooperative use of the video distributor, the video coder and the video camera, the analog-digital combination based video monitoring system improves image real-time performance, image quality and image safety of video monitoring while realizing remote video monitoring.

Description

technical field [0001] The invention belongs to the field of video monitoring systems, in particular to a video monitoring system based on the combination of analog and digital. Background technique [0002] With the development of multimedia technology, the previous analog video surveillance system is gradually replaced by digital network video surveillance system. From the perspective of resource utilization and user interests, the analog video surveillance system will continue to exist for a certain period of time, but the newly constructed systems basically use digital network video surveillance systems, so analog and digital video surveillance systems will coexist within a certain period of time. For users who have already built analog video surveillance systems, if they want to continue to expand the analog video surveillance system, it is obviously not in line with the technological development trend; but if the digital video surveillance system is used for expansion,...

Problems solved by technology

For users who have already built analog video surveillance systems, if they want to continue to expand the analog video surveillance system, it is obviously not in line with the technological development trend; but if the digital video surveillance system is used for expansion, the two mutually incompatible systems will lead to The cost of construction and operation has increased significantly; if the old analog video surveillance system is directly eliminated, it is obviously a waste of resources

[0003] In the traditional analog video surveillance system, the transmission is very sensitive to the distance, and cannot be connected to the Internet, which makes the wiring engineering huge. At the same time, the storage of the analog video signal will consume a large amount of storage media, and the query and evidence collection is very cumbersome.
