Embodiment Construction

[0032] Aiming at the incompatibility between the video monitoring platform and the network camera caused by the current network cameras adopting the proprietary control protocol, the solution proposed by the present invention is to use the extension of the SIP protocol as the control command, so that the control The method is simple and general, and solves the problem of incompatibility between different video surveillance platforms and different network cameras; in addition, using the SIP session initialization protocol that has been adopted between the video surveillance platform and the network camera, the video surveillance platform sends control commands through this network channel, So as to solve the problem of private network traversal.

[0033] In the present invention, it is proposed to define the control command of the network camera in XML format, as shown in Figure 1, including: SIP header information and specific control command content, wherein,

Abstract

The utility model relates to a network camera uniform control system based on the SIP extension, comprising a monitoring client, a video monitoring platform and a network camera; wherein the monitoring client is used to code the input information of the users into control parameters of the network camera in XML format and sends at least one control parameter as a control instruction to the video monitoring platform via a SIP pathway; the video monitoring platform is used to send the control instruction to the network camera via the SIP pathway; the network camera is used to receive the control instruction according to a unified software interface and executive the corresponding operation according to the XML control parameter in the control instruction. The utility model solves the problems of non-compatibility of different video monitoring platforms and different network cameras and the private network traversing in control process.

Description

technical field [0001] The invention relates to a unified control method and system for a network camera based on SIP (Session Initiation Protocol, Session Initiation Protocol) expansion under the Internet (Internet) environment. Background technique [0002] Video surveillance services have been widely used in industries and departments such as finance, transportation, water conservancy, public security, quality inspection and public safety. With the continuous development and improvement of modern communication technology and multimedia data encoding and decoding technology, surveillance cameras have gradually developed from analog and digital cameras to network cameras. The network environment of various monitoring systems is also gradually developing from private network and local area network to the Internet. The video surveillance service has gradually developed from a professional service only for the industry to a general video surveillance service for the general p...
