Remote video monitoring system based on session initialize protocol and its implementing method

Abstract

This invention relates to a remote video monitor system and a method based on the SIP protocol, in which, said SIP applied system is composed of a communication network, a front monitor device, a monitor center and a remote monitor customer end and an operation support platform and the communication network includes: IP network, PSTN network, ISDN and a mobile communication network,which takes the open SIP protocol as the core signaling protocol to realize the functions of system registration, setting up monitor session, transmitting monitor information and removing the monitor session and expand information body in the SIP short message to realize system session parameter negotiations, SIP short message transmission, adjustment of monitor parameters, managing and controlling front end monitor device, collecting charge information and expanding device kinds or increasing new control functions to meet the needs of open expansion applied needs and realize large scale applications by the current networks.

Description

technical field [0001] The invention relates to a remote video monitoring system based on a session initialization protocol and an implementation method thereof, belonging to the technical field of computer network and communication. Background technique [0002] The development of video surveillance system has gone through three stages of analog, semi-digital and full-digital, and it has been widely used in many fields such as communication, finance, transportation, mining and so on at home and abroad, and plays a huge role. With the development of related technologies, large-scale operation-level video surveillance services that are globally accessible, open and interoperable, and standardized are becoming new development needs. However, due to the lack of industry standards and low market access requirements, some equipment manufacturers blindly produce all kinds of video surveillance equipment in pursuit of commercial interests, resulting in the reliability, stability, o...

Problems solved by technology

[0006] Although the above two patent documents all relate to video telephony or video message, especially the former adopts the SIP protocol, they do not relate to the SIP application system and implementation method related to video surveillance. Therefore, with the popularization of video surveillance systems How to use the technical characteristics of the SIP protocol to develop a new video surveillance system that can overcome and solve many defects in existing technologies such as security, openness, and scalability as soon as possible has become an urgent need for scientific and technological personnel in the industry. a technological breakthrough
