A method and device for accessing third-party video surveillance equipment

Abstract

The present invention provides a method and device for accessing a third-party video surveillance device, wherein the network coordination device can pass through multi-layer NAT devices when counterfeiting a third-party video surveillance device to participate in the process of sending device information and detection messages, so that it can be applied to multiple Layer NAT device video surveillance system to improve its versatility. And while counterfeiting a third-party video surveillance device to participate in the process of sending device information and detection messages, it did not participate in the SDK access and video surveillance business operations of the third-party video surveillance device. Therefore, when deploying network coordination devices in the video surveillance system , the network coordination equipment does not change the interaction process between the existing third-party video surveillance equipment and the DA server, so that the video surveillance system does not need to make any changes to its own network architecture and existing third-party video surveillance equipment when deploying the network coordination equipment , so that the network coordination device has no performance bottleneck, and improves the flexibility and versatility of its use.

Description

technical field [0001] The present invention relates to the technical field of video surveillance systems, and more specifically, to a method and device for accessing third-party video surveillance equipment. Background technique [0002] The video monitoring system is a monitoring system that digitizes video information and transmits it through a wired network or wireless network, so that the video information within the monitoring range of the video monitoring system can be transmitted to devices located in the public network through the video monitoring system . [0003] The third-party video surveillance equipment used to obtain video information such as video recordings in the current video surveillance system, such as DVR (Digital Video Recorder, hard disk video recorder), NVR (Network Video Recorder, network hard disk video recorder) and IPC (IP Camera, network camera) such as Located in a private network, it can access the public network through a NAT (Network Addre...

AI Technical Summary

Problems solved by technology

After the static mapping is configured on the NAT device, other devices except the DA server can also access the third-party video surveillance device through the static mapping, making the third-party video surveillance device vulnerable to attacks from other devices, and the current public network address is large Some are dynamically allocated and may change at any time, so static mapping is not feasible
