MobileView PENTA Installation Manual 63
The MobileView PENTA DVR is configured by the installation contractor for
correct operation and space allocation. Do not change these options.
Caution: Storage allocation and usage options control the structure of the
recorder’s data file. Options cannot be changed without erasing and recreating
the data file, which results in permanent loss of all existing recorded data. Only
experienced operators should change storage allocation and usage.
The system data file stores all video, audio, GPS, and other recorded
information, as well as site details. The following rules apply to the creation and
management of the system data file:
• The system data file is a single file containing all recorded parameters,
indexes, and other necessary structures.
• Only experienced operators should manage the system data file.
• Changing the structure of the data file once it has been created results in the
loss of all stored video data.
• Sufficient space must be allocated for all parameters that are to be recorded
(video, sound, GPS).
Table 8: Storage allocation and usage options
Option Description
Total space available The total amount of disk space available on the drive where the data file
resides. This should be the full size of the storage drive.
Space to allocate The amount of disk space to allocate on the storage drive for the system
data file expressed as a percentage of the total space available. As the
storage drive should not be used for any other storage purpose, this
setting should always be set to 100% for normal operation.
Video data The amount of storage space within the system data file to allocate to
the storage of video data expressed as a percentage of the whole data
file size. As video pictures are generally the most storage intensive of
the recorded parameters, most space should be allocated to the storage
of video data. Default value is 94%.
Sound data The amount of storage space within the system data file to allocate to
the storage of sound data expressed as a percentage of the whole data
file size. Space for sound recording is only required if sound recording
has been enabled or if it is intended that sound recording may be
required at some later time. Default value is 5%.
GPS data The amount of storage space within the system data file to allocate to
the storage of recorder or site positions (GPS locations from a mobile
recorder) and expressed as a percentage of the whole data file size. As
site locations or GPS data have minimal space requirements, the
percentage allocated to this can be small. Default value is 1%.
