Milestone XProtect Basis+ 6.5; Administrator’s Manual
If the device to which the camera is attached is not a video encoder device with several channels,
the video encoder channel indication in the sub-directory named after the device’s MAC address will
always be _1. Example: (e.g. 00408c51e181_1)
Storing Archives at Other Locations than the Default
Archiving Directory
You are of course also able to store archives in other directories than the default archiving
directory. However, you cannot archive to external drives, only to a local drive on the computer
running XProtect Basis+ system.
Archiving Audio
If audio is enabled on a device, audio from the device will also be archived. If the device is a video
encoder with several channels, audio will be archived with the camera on channel 1.
When an audio source is enabled, audio is recorded to the associated camera’s database. This will
affect the database’s capacity for storing video. It is thus important to bear in mind that the
maximum limit of the database is likely to be reached earlier if recording audio and video than if
only recording video.
You may thus want to archive more frequently if recording audio and video than if only recording
video.
Storage Capacity Required for Archiving
The storage capacity required for archiving depends entirely on the amount of recordings you plan
to archive.
Some organizations want to keep archived recordings from a large number of cameras for several
months or years. Other organizations may only want to archive recordings from one or two
cameras, and they may want to keep their archives for much shorter periods of time.
Before enabling archiving, you should always consider the storage capacity of the local drive
containing the default archiving directory to which archives are always moved, even though they
may immediately after be moved to an archiving location on a network drive: As a rule of thumb,
the capacity of the local drive should be at least twice the size required for storing the databases of
all cameras for which archiving has been specified.
Note: You cannot archive to external drives, only to a local drive on the computer running XProtect
Enterprise.
In short: When estimating storage capacity required for archiving, consider your organization’s
needs, then plan for worst case rather than best case scenarios.
Tip: Milestone’s server estimator and storage calculator features, found in the Support section
of the Milestone website, www.milestonesys.com, can help you easily determine the capacity
required for your surveillance system.
Automatic Response if Running Out of Disk Space
With archiving, XProtect Basis+ can automatically respond to the threat of running out of disk
space. Two scenarios can occur, depending on whether the camera database drive is different
from, or identical to, the archiving drive:
