Abstract

The invention provides an intelligent gateway for an SIP terminal to access an ONVIF monitoring device. The intelligent gateway comprises an SIP module, an SIP and ONVIF conversion module, an ONVIF module and a streaming media forwarding module. The SIP module is responsible for interacting with the SIP terminal. The SIP and ONVIF conversion module is responsible for converting SIP information andinformation (SOAP and RTSP) used in the ONVIF. The ONVIF module is responsible for interacting with the ONVIF monitoring device. The streaming media forwarding module is responsible for receiving media streams from the ONVIF monitoring device, and forwarding the media streams to the corresponding SIP terminal according to a corresponding stream quotation relation. Through mutual cooperation of the four modules, the SIP terminal is enabled to access the media streams of the ONVIF monitoring device. The intelligent gateway is advantaged by low threshold, wide covering range, high timeliness, network-based performance and economical and practical performance.

Description

technical field [0001] The present invention relates to the technical field of video surveillance, in particular to an intelligent gateway for a Session Initiation Protocol (Session Initiation Protocol, SIP) terminal to access an ONVIF (Open Network Video Interface Forum, ONVIF) monitoring device for a real-time video surveillance scene. Background technique [0002] With the development of society, the arrival of the Internet age, and the needs of people's daily work and life, the monitoring system has become more and more important. In recent years, with the development of network video surveillance systems, network communication protocols have become increasingly diverse, and communication between protocols has become increasingly difficult. The SIP protocol, with its strong technical advantages, soon became the protocol adopted by many manufacturers. After many manufacturers adopt the SIP protocol, the interconnection between systems and the connection between systems a...
