This tab is designed for working with video files saved either manually or automatically.
You can save the files manually on the Playback tab. The files are saved automatically in the following cases:
a notification with the action Save a video as a file is triggered;
a device sends a file after detecting an event.
The video quality of the files depends on the device quality settings.
Particularities of storing video files:
- The limit on the size of the saved files of a unit is 5 GB. If it is reached, the older files are automatically deleted as soon as the new ones are saved. The files marked as important are not deleted in this case.
- The files older than the history period are automatically deleted.
- If a unit is deleted, deactivated, or video billing is disabled for it, its files are stored for another 30 days after that, and then deleted. This limitation doesn't apply to watching videos or live videos when the data is stored on third-party servers (for example, SmartWitness Gateway or CMSV6 Gateway) because Wialon stores only links to these files in this case.
After switching to the Files tab, the work area may show a list of units or a list of files of a particular unit, if you have already selected it on another tab.
Unit list
The unit list contains units for which cameras are configured. The number of cameras is indicated opposite the unit name. Units that are offline are marked with the icon 
.
Above the list, you can see a dynamic filter to quickly find units by name, as well as the following features:
| Icon | Action |

File list
The file list contains all the saved files of the unit.
The file row shows the following information:
- Name. If a file has been saved as a result of a notification action, it has the same name as the triggered notification. If files have been saved manually, they are named Saved manually. If sent by the device automatically, they are named Detected by device or have a name generated by the device automatically.
- Date. The day and time that you have indicated while requesting a file manually or the time of automatic registration of the video file.
- Tag. The tag points to how the file has been saved. If a file has been saved manually, you can see the tag selected by the user when saving it. If a file has been saved by means of a notification, its tag is named after the type of the notification. If the file has been detected by device, the tag is Detected by device.
- File size. The size of the downloaded file.
