DEMS Deployment Scenarios
Standalone
DEMS is running on a single computer. Media files can be stored either on this computer
or on external storage.
Advantages:
-
Does not require technical expertise
-
Minimal maintenance required
-
No network connectivity required
Implications:
-
A maximum of 18 cameras can be connected and uploading to DEMS at any point
-
Evidence cannot be viewed on other computers (but DVD copies can easily be
made)
-
Evidence is not held at a remote & secure location
Recommended Operating System:
-
Windows 8
Supported Operating System:
-
Windows XP SP3 and above
DEMS deployment Scenarios
Recommended Network Connectivity:
-
None
Required Pre-Installed Software (comes with DEMS):
-
Microsoft .NET Framework 2.0 and 4.0
-
Microsoft SQL Server 2008 R2 Express
-
Visual C++ Runtime
-
RS3 codecs for Windows XP
-
IMAPI Service for Windows XP
DEMS deployment Scenarios
Workgroup
DEMS is running on 2 or 3 computers. These computers are connected to each other
through a mini network with one acting as the server. This scenario is suitable for relatively
small deployments on a network (normally within the same building).
Advantages:
-
Installation requires only basic technical skills
-
Minimal maintenance required
-
Evidence can be viewed over the network on each computer
Implications:
-
The number of cameras able to upload at any point is limited by the number of
computers in the workgroup, where every computer can have a maximum of 18
cameras connected at any point
-
Evidence is not held at a remote & secure location
Recommended Operating System:
-
Windows 8
Supported Operating System:
-
Windows XP SP3 and above
DEMS deployment Scenarios
Recommended Network Connectivity:
-
Multiple Ethernet cables with a hub or a router connecting the computers
Required Pre-Installed Software (comes with DEMS):
-
Microsoft .NET Framework 2.0 and 4.0
-
Microsoft SQL Server 2008 R2 Express
-
Visual C++ Runtime
-
RS3 codecs for Windows XP
-
IMAPI Service for Windows XP
DEMS deployment Scenarios
Enterprise
DEMS is running on multiple client computers connected to a server over a wide area
network.
Advantages:
-
Central control, reporting and audit of all evidence, users and cameras
-
View any videos anywhere
-
Upload any camera at any location
-
No practical limit on number of cameras to be managed
-
Active directory support allows single sign-on
-
All evidence held centrally
Implications:
-
The installation process requires IT skills
-
IT skills needed to maintain the system and to carry out future upgrades
-
Files need to be transferred over the corporate network. Sufficient bandwidth
must be available.
DEMS deployment Scenarios
Recommended Operating System:
For Server Computer:
-
Windows 2008 R2 Server SE
For Client computers:
-
Windows 8 Enterprise
Supported Operating System:
For Server Computer:
-
Windows server 2003 R2 family (except Web Edition) and above
For Client computers:
-
Windows XP SP3 and above
Recommended Network Connectivity:
-
Through the organization’s existing network infrastructure
Required Pre-Installed Software:
For Server Computer:
-
Microsoft .NET Framework 2.0 and 4.0
-
Microsoft SQL Server 2008 R2 Express with Management Studio
-
Microsoft IIS
-
Visual C++ Runtime
For Client Computers:
-
Microsoft .NET Framework 2.0 and 4.0
-
Visual C++ Runtime
-
IMAPI service for Windows XP computers
-
RS3 codecs for Windows XP computers
DEMS deployment Scenarios
Hybrid
Similar to the enterprise scenario where all database information is held centrally. In this
case the videos themselves are held at the location which they were uploaded to avoid
the need to transfer them over the network; this scenario delivers many of the advantages
of the Enterprise scenario without utilising significant bandwidth.
Advantages:
-
Central control, reporting and audit of all evidence, users and cameras.
-
View any videos anywhere (if view low resolution files facility is enabled)
-
Upload any camera at any location
-
No practical limit on number of cameras to be managed
-
Active directory support allows single sign-on
Implications:
-
The installation process requires IT skills
-
IT skills needed to maintain the system and to carry out future upgrades
-
Files need to be transferred over the corporate network if low resolution playback
is used. Sufficient bandwidth must be available.
-
Evidence is not held at a remote & secure location
DEMS deployment Scenarios
Recommended Operating System:
For Server Computer:
-
Windows 2008 R2 Server SE
For Gateway and Client computers:
-
Windows 8 Enterprise
Supported Operating System:
For Server Computer:
-
Windows server 2003 R2 family (except Web Edition) and above
For Gateway and Client computers:
-

-
Microsoft .NET Framework 2.0 and 4.0
-
Microsoft SQL Server 2008 R2 Express with Management Studio
-
Microsoft IIS
-
Visual C++ Runtime
For Gateway and Client computers:
-
Microsoft .NET Framework 2.0 and 4.0
-
Visual C++ Runtime
-
IMAPI service for Windows XP computers
-
RS3 codecs for Windows XP computers
