Example: With the default archiving folder located under C:\videodata, images from an archiving
taking place at 23.15 on 1st June 2005 for a camera attached to channel 2 on a video encoder
device with the MAC address 00408c51e181 would be stored at the following destination:
C:\videodata\Archives\00408c51e181_2\2005-06-01-23-15
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 at other locations than locally in the default archiving
directory. You may, for example, specify that your archives should be stored on a network drive.
When archiving to other locations than the default archiving directory, NetDVMS will first store
the archive in the local default archiving directory, then immediately move the archive to the
archiving location you have specified.
While this may at first glance seem unnecessary, it greatly speeds up the archiving procedure,
which will reduce delays in case of network problems.
Archiving directly to a network drive would mean that archiving time would vary depending on
the available bandwidth on the network. First storing the archive locally, then moving it, ensures
that the archiving is always performed as fast as possible.
If archiving to a network drive, note the regular camera database must still be stored on a local
drive, i.e. a drive attached directly to the computer running the NetDVMS 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.
Automatic Archiving if Running Out of Disk Space
In case the server is running out of disk space, and
o
the archiving drive is different from the camera database drive, and
o
archiving has not taken place within the last hour,
archiving will automatically begin in an attempt to free up disk space. This will happen regardless
of any archiving schedules, but will of course only apply for cameras for which archiving has been
enabled in the Archive Setup window .
The NetDVMS server is considered to be running out of disk pace if its available disk space goes
below 150 MB plus 20 MB per camera. Example: For a system with ten cameras, the server will
