Video backup method and system based on security and protection home gateway

Abstract

The invention discloses a video backup method and system based on a security and protection home gateway. The video backup method comprises the following steps that: the home gateway of a network video system periodically sends a link detection report to a server and judges whether a current network state is normal or not according to a link reply report responded by the server; if the current network state is normal, the home gateway uploads current video data of the network video system to the server; and if the current network state is abnormal, the home gateway stores the current video data of the network video system to a local storage space of the home gateway. The video backup method and system provided by the invention solve the problem that a home gateway monitoring video cannot be stored into a long-distance video storage server when the long-distance video storage server or a network is abnormal in the prior art through a local data backup mechanism when the network is abnormal, so that the integrity of video data can be effectively ensured, and the risk of losing the video data can be reduced.

Description

technical field [0001] The invention relates to the field of home gateway video monitoring, in particular to a method and system for transferring the monitoring video to the home gateway for local storage and uploading the stored video when the remote storage of the video monitoring in the security aspect of the home gateway is abnormal. Background technique [0002] The network video monitoring system transmits video information in digital form through a wired or wireless IP (Internet Protocol, a protocol for interconnection between networks) network. As long as the home gateway can reach the place, video monitoring and recording can be realized, and This monitoring can be perfectly integrated with many new systems. [0003] Video surveillance is an important part of the security field. It is a comprehensive system with strong prevention capabilities. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information cont...
