Set the [Settings] Tab

Enter [Recorded Video Settings]

1. [Maximum retained history] - Check the [Maximum retained history] option and enter a value from 1 to 999

and then select [Days] or [Weeks] from the pull-down menu.

[Maximum file size/duration] - Check the [Maximum file size/duration] option, enter a value, and select [MB]

or [Hours]. You can enter 32 - 1024 for [MB] and 1 - 24 for [Hours]. If you do not enter a value, 1024 MB or

24 hours is used for the Maximum file size/duration value.

3. [Low disk space warning level] - Enter a percent value.

When the remaining space falls below the specified value, the event will be displayed and a notification will

be e-mailed ( P. 3-5, P. 3-23).

[Reduce recording frame rate when disk is under high load] - When disk is highly loaded, recording frame

rate is temporarily reduced to prevent the recording from stopped. See Chapter 6 for details. This function is

available for JPEG video recording. It cannot be used for MPEG-4 video recording (VB-C500D, VB-C60).

Tip

If [Reduce recording frame rate when disk is under high load] is selected, you will receive an event

notification such as "Effective Recording rate (<recording rate before change>  <recording rate after

change> %)" when the recording frame rate drops.

Ex. Effective Recording rate (100.0  90.0 %)

Note

When the free disk space has fallen below the value specified in the [Low Disk Space Warning Level] field,

an event occurs and an event notification mail is sent. Also, if the used disk space exceeds the value spec-

ified in the [Maximum disk space used] field, recorded video will not be saved until the required free disk

space is secured. See P. 3-17 for the disk space management.
