Embodiment Construction
[0034] In order to connect the monitoring front-end equipment to the monitoring network, the present invention designs an agent device Agent, which is used to assist the monitoring front-end equipment to communicate with the monitoring network to be connected, and does not consume public network addresses. The Agent is a logical concept, which can be placed in various physical entities, for example, placed on a monitoring front-end device, or placed on an ordinary PC. Because some current monitoring systems, such as the monitoring system of the park mentioned in the background technology, the monitoring system of the supermarket, each monitoring front-end equipment usually communicates with the PC in the monitoring room, so it is necessary to install the Agent on the PC in the monitoring room. An ideal choice. Through the following description, we can find that in the solution of the present invention, each monitoring front-end equipment can easily be networked with the back-e...

The invention provides a method for connecting monitor front-end equipment to a monitor network. The monitor front-end equipment is connected to the monitoring and control network through the Agent of the monitor front-end equipment. The Agent actively initiates a connection to a Server, and a channel is built and maintained. The Agent applies for a virtual IP of the monitor front-end equipment from the Server and maintains the virtual IP. Interaction is used for carrying out interaction on a DA connecting the monitor front-end equipment to a third party network and the monitor front-end equipment. All signaling between the DA and the monitor front-end equipment passes through the channel and is transmitted after being processed by the Server and the Agent. A media stream does not pass through the channel and is directly sent to the DA from the monitor front-end equipment. According to the scheme, when the monitor front-end equipment is connected to the monitoring and control network, the monitor front-end equipment is not modified, software with the Agent function, the Server function and the DA function of the method is arranged on an existing physical entity, and therefore ideal access of the monitor front-end equipment is achieved, cost is low, and the work load of modification is small.
Description
technical field [0001] The invention relates to the technical field of video monitoring, in particular to a device and method for realizing networking of monitoring front-end equipment. Background technique [0002] With the development of information technology represented by digitalization and networking, the theory and technology of social security prevention have undergone a complete transformation. The traditional video surveillance technology no longer meets the needs of the development of the times. The network video monitoring system based on the Internet has gradually become the development direction of the monitoring field, and the demand for networked monitoring in various industries is growing rapidly. [0003] However, in practical applications, traditional video surveillance systems still occupy a certain proportion, and will continue to exist for a certain period of time. In order to make full use of these existing monitoring resources, these monitoring resou...
