5 Description of "Site archive" features
40 Vista SmartDisc 10IP
The illustration shows identical partitioning (factory setting) for each of the
10 camera tracks of a SmartDisc 10IP hard disk. The required storage
capacity is based on average picture size, recording mode, recording speed,
and recording duration. Set the partition size using the thumb. No images are
recorded on a camera track when the storage capacity is set to 0%.
FIFO SmartDisc 10IP uses FIFO (First In First Out) for recording. The oldest images
or events will be overwritten with new recordings after a certain period of
time. Hard disk partitioning into camera tracks prevents recorded images
from being overwritten by data from other cameras.
Record preview
images
When accessing the image archiving device remotely over a low bandwidth
connection, low-resolution preview pictures (256 x 128 pixels) can be stored
in the archive. These preview pictures can be used to view the recorded
pictures more quickly during remote access. When preview pictures are saved
during recording, recording speed is slowed down by about 20%. Recording
duration is reduced by approximately 10%, as additional storage space is
required for preview images.
Overwrite
protection
Activating overwrite protection ensures that existing recordings are never
deleted automatically. Individual camera tracks must be released before
overwrite. An individual storage warning threshold can be defined for each
track. Reaching the threshold warning limit (to be set in percentiles) triggers
the SmartDisc 10IP error LED to illuminate and a log file entry to be written.
In addition, a message advising that the threshold warning limit has been
reached can be sent via e-mail. The threshold warning limit can be reported
by relay as well, depending on device configuration. For remote evaluation
with SmartControl or SmartControl PRO software a message is displayed
that only dedicated image export or switching removable hard disks will
ensure permanent image storage.
Report period less
than [] days
This option allows the device to issue a warning (error LED, error relay, online
evaluation, log file) if the specified recording duration for an individual track
cannot be maintained any longer. SmartDisc 10IP uses the previous
recordings as a basis for calculation, extrapolating from an assumed regular
data volume. Based on the quantity of data saved on the hard disk and the
previously recorded time period, an estimate is made of how long (in days)
the available storage space would last. If this period is less than the set value,
the error relay can be activated, for example.
Delete all pictures
older than [] days
If special requirements for the period of image storage must be complied
with, for example for reasons of data privacy, a maximum age can be
specified for archive images per camera track. Any older images will then be
deleted automatically.
The archive is reformatted when the track storage capacity is changed. All images
recorded up to this point will be irretrievably deleted.
When recording images from IP cameras, no preview images are stored.
