Maximum size
Select the maximum number of gigabytes of recording data to save
in the recording database.
Recording data in excess of the specified number of gigabytes is
auto-moved to the first archive in the list - if any is specified - or
deleted.
Important: When less than 5GB of space is free, the system
always auto-archives (or deletes if no next archive is defined) the
oldest data in a database. If less than 1GB space is free, data is
deleted. A database always requires 250MB of free space. If you
reach this limit (if data is not deleted fast enough), no more data is
written to the database until you have freed enough space. The
actual maximum size of your database is the amount of gigabytes
you specify, minus 5GB.
Schedule
Specify an archiving schedule that outlines the intervals with which
the archiving process should start. You can archive very frequently
(in principle every hour all year round), or very infrequently (for
example, every first Monday of every 36 months).
Reduce frame rate
To reduce FPS when archiving, select the Reduce frame rate
check box and set a frame per second (FPS).
Reduction of frame rates by a selected number of FPS makes your
recordings take up less space in the archive, but it also reduces the
quality of your archive.
MPEG/H.264 reduces automatically to key-frames as a minimum.
0.1 = 1 frame per 10 seconds.
Attach a device or group of devices to a storage
Once a storage area is configured for a recording server, you can enable it for individual devices such
as cameras, microphones or speakers or a group of devices. You can also select which of a recording
server's storage areas you want to use for the individual device or the group.
1. Expand Devices and select either Cameras, Microphones or Speakers as required.
2. Select the device or a device group.
3. Select the Record tab.
4. In the Storage area, select Select.
5. In the dialog box that appears, select the database that should store the recordings of the
device and then click OK.
6. In the toolbar, click Save.
When you click the device usage number for the storage area on the Storage tab of the recording
server, the device is visible in the message report that appears.
