location. We strongly recommend that you either configure a single
overwrite setting, or that you estimate, in advance, the capacity you will
use, based on the image size and required storage period specified for the
camera, and configure the deletion settings for recordings accordingly.
When the recorded data of normal recordings is overwritten, multiple
files in a single record are deleted at once. This may cause all the files of
a particular camera to be deleted at once. By configuring the following
settings, you can ensure that data from multiple cameras is deleted more
uniformly.
- In a recurrent schedule for normal recording, insert at least one second
of blank space per day.
Ex.) Start time: 00:00:00 End time: 23:59:59
Notes
If the recording capacity of the built-in hard disk is insufficient, you can
expand it with external storage. For details about storage expansion,
contact your dealer.
The following storage locations are defined by the NSR and cannot be
deleted.
- Default
-Alarm
- Manual
-Normal
The above four storage locations are actually located in the same partition
but in different directories (folders). As a result, the capacity and total
size of these storage locations are all the same, but deleting and
overwriting are performed independently for each directory (folder).
For NSR storage locations, you can configure the main settings related to
deletion and overwriting of recordings, and set the storage period for
each type of recorded image. However, it is not possible to assign a
capacity to each storage location.
The Default location is the default save location for each camera. To set
different save locations for each camera, you can use the storage settings
in “Main” under “Camera” on the Configuration screen.
Four storage setting examples are provided below. Select a storage location
according to your objective and the recording type selected in the camera
storage settings.
Examples:
Default : Delete -disable, data overwrite-enable (20%)
Alarm : Delete -enable (30%, 366 days), data overwrite -disable
Manual : Delete -enable (40%, 7 days), data overwrite - disable
Normal : Delete -enable (50%, 31 days), data overwrite - disable
Descriptions:
Default : When the remaining capacity for the storage location reaches
20% or below, recorded images are deleted in order, starting
from the oldest images.

capacity remaining.
