B, when logining successfully, DVR device-dependent message is updated multiple equipment management module；
C, multiple equipment management module will create the corresponding logical layer of this equipment and download manager；
D, the DVR of successful connection is set to current device, interface is according to the logical layer of current device
Update；
Second step, the video recording in inquiry DVR:
Video recording in a, selector channel query time section, to inquire about video file；
If b inquires about unsuccessfully, return error message prompting, if successful inquiring, return file linked list；
Third step, downloads and records a video:
Corresponding download manager is searched according to DVR unique identifier (equipment id), after finding, adds to download and appoint
It is engaged in this download manager, starts to download, during download, consider equipment disk space problem, then external 1 Large Copacity portable hard drive.
The present invention has following advantages and a good effect:
1. multiple stage hard disc apparatus can be simultaneously connected with download, solve the disadvantage that conventional client can only download an equipment simultaneously
End；
2. provide a kind of method of unified management, can easily switch device downloads video file；
3. provide abnormal restoring mechanism, solve because extraneous factor lead to record a video collection unstable and often fail ask
Topic；
It is applied to the video acquisition of each big mainstream network DVR and digital DVR on market.
