A File Storage Method Oriented to Video Surveillance

Abstract

The invention relates to a video surveillance-oriented file storage method, comprising the following steps: creating a video surveillance file, the video surveillance file includes segment information, data segments and index segments, and the segment information is written in a place-occupancy manner. Receive video surveillance data through the network. If the video surveillance data is streaming data, then judge whether the streaming data is newly added; if so, then record the segment information and the index segment information of the streaming data in the internal memory; if not, then write the current frame of the streaming data Enter the data segment of the video monitoring file, and record the frame index information of the current frame in the internal memory; if the video monitoring data is signaling, then judge whether the signaling is the reason for the video recording; if so, add the reason for the video recording to the internal memory; If not, perform corresponding processing according to the signaling type. Close the video surveillance file. The method can reduce the number of seeks of the magnetic head, improve the performance of concurrent writing, and help improve the efficiency of analyzing the video after dumping the data.

Description

technical field [0001] The invention relates to the technical field of video surveillance file storage, in particular to a video surveillance-oriented file storage method. Background technique [0002] In the video surveillance system, an important function is the video recording function. Only a monitoring system with video recording function can conduct post-event video verification. There are two main ways of video recording: front-end storage and platform storage. In front-end storage, the number of cameras stored at the same time is generally relatively small, and the performance requirements are not too high. Since the deployment environment may be relatively harsh, more attention is paid to the stability of storage. When the platform is stored, the storage devices are generally placed in the computer room, so the storage device itself has high stability. However, when the platform is stored, the number of cameras generally managed is large, so the performance requir...

Problems solved by technology

In this way, the cause of the recording is separated from the recording, and it is impossible to quickly screen through the cause of the recording when analyzing again, which is not conducive to improving the analysis efficiency
