Administrative center based multiple spots interactive method for network video monitoring control

Abstract

A network video frequency monitoring control multiple spot interaction method based on an administrative center which comprises, arranging an administrative center for uniform management for on-site end control and far-end users, the administrative center maintaining the state table of the on-site supervision end on one hand, and managing the extent of authority for the users on the remote monitoring control end, then adopting two transmission strategies to the audio-video information and alarm signal.

Description

technical field [0001] The invention relates to a network video monitoring method, in particular to a multi-point interactive method of network video monitoring based on a management center. It belongs to the field of network technology. Background technique [0002] In many cases, each on-site monitoring terminal in a network video surveillance system needs to monitor the monitoring site separately. When an abnormal situation occurs, an alarm is sent to the remote user in real time, and the legal remote user connects to the on-site monitoring terminal through the network. , Receive audio and video information and alarm signals from the monitoring site. Through literature search, it is found that the patent name is: multifunctional computer remote video monitoring system, patent application number 98112367.8, the system includes multiple on-site monitoring terminals and multiple remote monitoring terminals. In addition to the general network video monitoring module, the on...

Problems solved by technology

However, on the one hand, when the number of on-site monitoring terminals or remote monitoring terminals is large, it will be very difficult to manage users and maintain the list of on-site monitoring terminals. If you want to modify the authority of one of the remote monitoring terminals, all On-site monitoring terminals must be adjusted. Similarly, if the on-site monitoring terminal is to be increased or decreased, the on-site monitoring terminal list of each remote monitoring terminal must be adjusted. On the other hand, because the importance of audio and video information and alarm signals is not Similarly, a certain degree of loss of audio and video information can be tolerated, but the alarm signal needs to be transmitted reliably, so sending the two kinds of information together will reduce the reliability of the alarm signal or will cause the reliability of the audio and video information to be too high. It leads to a waste of network bandwidth and affects the real-time performance of audio and video information
