Implementation method of information acquisition and control of video surveillance equipment

Abstract

The invention involves a video monitoring equipment information collection control implementation method, including the survival of the IP address, and determining whether the IP address is surviving; otherwise, the withdrawal steps; analyze the traffic of the protocol through PCAP technology and deep package detection technology, identify assets of assets, identify assetsInformation, get DPI_DATA data; send an analog SDP request to the IP address. By parsing the XML file, the specified key string is extracted to describe the device parameters to obtain the UPNP_DATA data;The type of information obtaining video monitoring equipment is based on technical parameter information.The implementation of a video surveillance equipment information collection control implementation method of the present invention is adopted. Through the technical solution of data communication protocol analysis and active passive mode, the accuracy of technical parameter information is improved and comprehensive.Through the collision algorithm and model fit, the digital model is established on the unknown device, and the traditional method is relied on the traditional method to rely on the fingerprint library.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to the technical field of digital communication, and specifically refers to a method for realizing information collection and control of video monitoring equipment. Background technique [0002] The collection technology for asset category and asset technical parameter information of video surveillance equipment (including cameras, DVRs, NVRs, and management servers) used to use IP detection to find equipment on the network and obtain equipment through port scanning. Open ports and open service types, and then add a label to the device according to the BANNER information of the application service obtained by the crawler. The main purpose of this technology is to obtain the BANNER information of the equipment open service to provide relevant data retrieval and manual judgment of equipment assets. Because this technology only follows the traditional Internet asset colle...

AI Technical Summary

Problems solved by technology

Because this technology only follows the traditional Internet asset collection method, there are still deficiencies in the discovery and identification of video surveillance equipment assets in the internal network: 1) For devices that enable access control such as filtering in the internal network environment, this technology cannot discover the device's Some ports exist and cannot be found, resulting in incomplete collection of device information; 2) This technology only crawls and identifies various BANNER information of open services of the device, and does not judge the asset type of the device. After manual query, according to Judging the asset type of the device based on experience; 3) This technology cannot discover and identify more detailed device type information such as firmware version number, API, SDK, device detailed version number, data communication protocol usage, and operating system
