RC-E User Manual
Enabling/Disabling Individual Devices
Cameras are by default enabled. Microphones, speakers, inputs and outputs are by default disabled.
This means that microphones, speakers, inputs and outputs must be individually enabled before they can be used on
the RC-E system. The reason for this is that surveillance systems inherently rely on cameras, whereas the use of
microphones, etc. is highly individual depending on organizations' needs.
In the overview pane (see "Panes Overview" on page 36), under the required server, enabled/disabled devices are
indicated:
The same method for enabling/disabling is used for cameras, microphones, speakers, inputs, and outputs.
Enabling
1. In the overview pane (see "Panes Overview" on page 36), expand the required recording server and the
required hardware device. Right-click the camera, input, or output you wish to enable.
2. From the menu that appears, select Enabled.

About Storage and Archiving

When a camera or device records video and/or audio, all specified recordings are per default stored in the storage
area defined for the device. More precisely in the storage area's default recording database named Recording. A
storage area has no default archive(s), but these can easily be created.
Depending on recording settings, the storage areas's recording database will most likely run full at some point and its
contents need to be archived in order to be saved. It is therefore possible to create archives within the default storage
area and start an archiving process. Furthermore, it is possible to create alternative storage area(s) and configure that
selected video/audio recordings must be stored/archived here.
Archiving is the automatic transfer of recordings from a camera's or device's default database to another location. This
way, the amount of recordings you are able to store will not be limited by the size of the device's recording database.
Archiving also makes it possible to back up your recordings on backup media of your choice.
Storage and archiving is configured on a per-recording server basis.
To ease explanations, the following mostly mentions cameras and video, but al is true about speakers and
microphones and audio and sound as well.
IMPORTANT: We recommend that you use a dedicated hard disk drive for the recording server database. Using a
dedicated hard disk drive for the database will prevent low disk performance. Furthermore, when formatting the hard
disk, it is important to change its Allocation unit size setting from 4 to 64 kilobytes. This is to significantly improve
recording performance of the hard disk. You can read more about allocating unit sizes and find help at
http://support.microsoft.com/kb/140365/en-us (see http://support.microsoft.com/kb/140365/en-us -
http://support.microsoft.com/kb/140365/en-us).
IMPORTANT: The oldest data in a database will always be auto-archived (or deleted if no next archive is defined)
when less than 5GB of space is free. If less than 1GB space is free, data will be deleted. A database always requires
250MB of free space; if this limit is reached (if data is not deleted fast enough), no more data will be written to the
database until enough space has been freed. The actual maximum size of your database will thus be the amount of
gigabytes you specify, minus 5GB.
Attaching Devices to a Recording Server
Once you have configured the storage area and archiving settings for a recording server (where to store recordings,
archives, how often to transfer recordings to archives, etc.), you can enable storage and archiving for individual
