Introduction
The 4RE DVR uses USB flash drives formatted using the FAT32 file system. If there is an issue with the USB, try to format it as FAT32 in a PC, or on the 4RE DVR under Menu -> Settings -> Diagnose -> Format USB.
In firmware versions 4.x and above:
A USB flash drive can contain any combination of the following input files:
- Scripts
- DVR configuration files
- Firmware upgrades
- Test scripts
It will prompt the user to select from a list of available options.
Example 1:
The USB flash drive has:
- upgrade.zip
- DVR WGV video files
The DVR will NOT use the DVR WGV video files. The DVR will only see the upgrade file and use it.
Example 2:
The USB flash drive has:
- DVR configurations
- DVR WGV video files
- Two documents
The DVR will only use the DVR configurations and ignore the other data.
Example 3:
The USB flash drive has:
- DVR configurations
- Firmware upgrade files
The DVR will prompt you to choose whether to use the USB to upgrade/downgrade the DVR firmware or to deploy a configuration.
Comments:
The DVR is looking for specific folders and files on the USB flash drive. They are:
- UPGRADE files: [USB]:\upgrade.zip
- Configuration Files: [USB]:\wgv\config\ (any .xml files)
- DVR Video: [USB]:\wgv\ (.mtd, .xml and .ts files)
