to be segregated due to, for example, the nature of data, special regulations,
specific discipline demands or different on-line persistence needs.
Estimate the Database Size for HDB to Determine the SQL Server Edition
The amount of collected historical data and the storage of the data to the HDB is
highly condition specific. The System Dimensioning Tool (p. 38) provides
indications about the edition and the database size most suitable for a specific
project.
Please see section History Database in the Desigo CC Help for details on how to
size the HDB and determine the adequate SQL Server edition.
System Limits
There is a 10 GB limit to the SQL Server Express database, and of 250 GB for
SQL Server.
1.2.1.5 Video Service
The Desigo CC Video Service runs on Desigo CC Server and connects either to
the Video Management Services or to an external Video Management System
(VMS).
The Video Management Services provide the capabilities of a Video Surveillance
System inside Desigo CC. The Video Management Services can be installed on
the main server or on a separate machine.
For small systems, the Network Video Recorder (NVR) service can be installed on
the main server. To reduce the bandwidth demands of the network and the
required resources on the server, further NVR services can be distributed on other
machines and storage devices. External Video Management Systems provide their
own service architecture.
➜ For additional details, please refer to the engineering manual of the external
VMS.
Only one Video Service is allowed in a distributed system configuration.
1.2.1.6 Client Options
Desigo CC supports multiple client options for applications ranging from occasional
users to dedicated mission-critical console installations. All client options are built
around the same usability standards and capabilities making it easy to switch
between different client options without the need to learn multiple interfaces.
User privileges can be assigned to users and to workstations, allowing users to be
granted the same access from everywhere or different access depending on where
they are logged on.
Windows App Client
The Desigo CC Windows App Client software is a light application that can be
downloaded from the Desigo CC Server through a browser. When the Windows
App Client is downloaded, it runs like any other Microsoft Windows desktop
applications. The Windows App Client is not installed but instead run by the
Microsoft .NET runtime environment. It can be launched from the Start menu, from
a desktop icon, or from the Quick Launch toolbar. This deployment does not
require administrative privileges.
Depending on the configuration, Windows App Clients can have the same
functionality as Installed Clients (Identified by certificate) or are restricted by other
access mechanisms (anonymous client).
