Storing method for file monitored by video

Abstract

The invention relates to a storing method for a file monitored by video. The storing method for the file monitored by video comprises the following steps: establishing video monitoring file, the video monitoring file comprises segment information, data segment and index segment, and writing the segment information by adopting the placeholder way; receiving the video monitoring through a network; if the video monitoring data is stream data, judging whether the stream data is new; if yes, recording the segment information and the index segment of the stream data in a memory; otherwise, writing the current frame of the stream data into the data segment of the video monitoring file, recording the frame index information of the current frame in the memory; if the video monitoring data is signaling, judging whether the signaling is the video reason; if yes, adding the video reason in the memory; otherwise, performing the corresponding treatment according to the signaling type; closing the video monitoring file. The track seeking times can be reduced for the magnetic head by adopting the method, the concurrent write performance is improved, and the efficiency for analyzing video is effectively improved after data transcription operation.

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 a video surveillance system, an important function is the video recording function. Only a monitoring system with a video recording function can conduct post-event video verification. There are two main methods of video recording: front-end storage and platform storage. For 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. For platform storage, the storage devices are generally placed in the computer room, so the storage device itself has high stability. However, for platform storage, the number of cameras generally managed is large, so the performance requirements f...

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
