Video Architectures and Limits

Integrating video surveillance into Desigo CC requires two specific software components:

  • Video Management System (VMS): Handles the physical connection to video devices and supports video services. This is a distinct software component that must be separately installed and configured to work with Desigo CC.
    NOTE: It is possible to use VMS solutions from different providers, including Milestone and Siveillance (contact your nearest sales representative).
  • Video extension: Installs a component (BT Video API) on the Desigo CC server which acts as an interface to the VMS.

The VMS can be installed on the same computer as the Desigo CC server (local VMS) or on a separate one (networked VMS).

Architectures for small and large installations
The local VMS solution is suitable only for small installations. Networked VMS server is the preferred solution for video systems, and should always be applied to medium and large size installations. For more information see the limits in the table below.

 

Local and Networked Video Architectures

Video Connectivity Limits

Local VMS Deployment

Networked VMS Deployment

The VMS runs on the same computer as the Desigo CC server.

The VMS runs on a separate computer that connects to the Desigo CC server.

This solution is supported on small installations with a maximum of:

  • 2 client stations
  • 48 video cameras (including cameras disabled in the VMS)
  • 96 monitors
  • 6 monitor groups

NVRs (Network Video Recorders) can be local or remote:

  • 1 NVR is typically sufficient for the 48 cameras limit.

This solution can be applied to medium/large installations comprising a maximum of:

  • 20 client stations equipped with video, and using up to 36 independent video streams each
  • 2000 video cameras (128 for UL/ULC approved systems), including any cameras disabled in the VMS.
  • 800 monitors
  • 128 monitor groups

NVRs can be local or remote:

  • 4 NVRs are the minimum required for the 2000 cameras limit.
  • Supported Architectures with Additional VMS Servers: To allow remote access to a wide-area vide system, additional VMS servers can be interconnected with the main VMS server that is in turn connected to Desigo CC. However, The architecture with multiple VMS servers in Federated Site Hierarchy is not supported (only the main VMS server is visible from Desigo CC).
    NOTE: Support for multi-VMS server and multi-recorder solutions depends on the specific VMS provider.
  • Supported Architectures with Additional Desigo CC Servers: In a distributed management platform with interconnected Desigo CC servers, only one of the Desigo CC servers is directly connected to the VMS. The other Desigo CC servers instead access video through the connected one.
NOTICE

Recording and storage capacity

The NVRs and hard drive storage required for a specific configuration depend on the number of video cameras, their resolution, and the average recording time. For a correct sizing of the video recording and storage capacity, contact the technical support of the connected VMS.

 

Recommended Hardware for Video Stations

Computer Hardware Requirements for Video

Desigo CC server computer

 

  • PC hardware requirements depend on dimensioning of the installation, as set out in the Desigo CC System Description document. The minimum hardware category is MS.
  • Additionally, if the Desigo CC server computer also hosts the VMS (local deployment), it must meet the requirements of the installed VMS. Refer to the separate VMS documentation.

  • NOTE
    : The example on the right is just a typical--not minimum--configuration for a local deployment with a specific VMS provider. For full information about the hardware requirements always refer to the System Description and to the documentation of the VMS.

Example: Typical requirements for Desigo CC server computer that also hosts Milestone / Siveillance VMS

  • Supported operating systems:
  • Windows 10 64-bit
  • Windows 11 64-bit
  • Windows Server 2019 64-bit
  • Windows Server 2022 64-bit
  • PC hardware:
  • I7 Intel CPU or equivalent
  • 24 GB Ram
  • 2 x 2TB hard disks
  • Graphic card with 2GB Ram
  • 500 GB Operating System disk (for Windows server)
  • 1 SSD 256 GB Operating System disk (for Windows 10)

Desigo CC client stations that display video streams


NOTE
: These requirements also apply to the Desigo CC server station if it is used to display video streams.

The following requirements apply

  • General requirements for client stations, as set out in the Desigo CC System Description document. The minimum hardware category is MS.
  • Graphics card (GPU) that supports hardware acceleration. .
  • Additional hardware requirements for the VMS that is used. Refer to the documentation of the installed VMS.

In particular, for the Milestone/Siveillance VMS:
Hardware acceleration with Intel® Quick Sync requires an Intel® CPU 4th generation or newer, supporting Intel Quick Sync and Intel® GPU enabled in BIOS. Decoding with NVIDIA graphics card is supported with GPU capability version 6.x (Pascal) or newer

General Video Application Limits

 

Thick client stations:

  • Video streams: max 36 simultaneous streams per client station. These may be contained in a single pane layout, or subdivided among multiple layouts (for example, 32 in the primary pane, and 4 in the Assisted Treatment video step).
    NOTE: The simultaneous use of multiple video layouts (primary, secondary, event treatment) that exceed 36 streams in total may cause excessive CPU and memory usage, slowing down the client station.
  • CPU usage for video display: 8 simultaneous Full HD video streams or 36 simultaneous 4CIF video streams result in a typical CPU usage <33% and memory usage <830MB.
    (Test conducted on PC with I7-3770 3.4 GHz processor and Nvidia Quadro 2000D video card with 1 GB of memory, and with VMS running on a separate PC.)
    NOTE: Actual CPU usage depends on the frames per second (fps) and nature of the images (whether "static" or with many moving objects) received from the VMS

 

Flex client stations:

  • Video streams: max 10 simultaneous streams in total for all Flex client stations connected to the system. These may be subdivided in any way, for example, ten Flex clients each with one stream, five Flex clients each with 2 streams.
Video display on Flex stations

On Flex clients video streams are displayed as a sequence of 'snapshot' images (resolution 1024 x 768 pixels) with a limited refresh rate: 1 frame/second or less, depending on the type of camera, the performance of the network / VMS recording server, and the number of simultaneous streams.

A Flex station can display images from a camera only in a single-view. There are no multi-camera layouts (2x2, 4x4, and so on) as in the installed client. It is possible to have a single view of one camera in the primary pane, and a single view of another camera in the secondary.

Flex stations do not use monitors and monitor groups to display video images, so there is no interaction with the video displayed on any other station.

 

Technical Limitations for Siveillance / Milestone VMS integration with Desigo CC

The following constraints apply when the Milestone or Siveillance VMS is integrated with the management platform:

 

Known Issues for Milestone and Siveillance VMS:

This section lists the known issues with the current integration of these VMS providers into the management platform.

  • The first time a video stream from a camera is selected to display, loading of the stream may take 15 to 25 seconds depending on network and PC performance. Subsequent selections of the video stream will not have this delay.
  • Off-line configuration is not supported. You can only fully configure video on a running system with video devices connected.
  • Each Desigo CC project restart causes the video connection to stop. Operators must issue a new connect command from a client station after restarting the system project.

Video Support on Windows App Clients

The use of video on Windows App clients (formerly Click-Once clients) requires the following:

  • On each web station, run the setup program MilestoneProviderInstaller.msi from the Prerequisites\BT_Video_API folder of the installation files.
    NOTE: This setup is included in the Desigo CC client setup. Therefore, you do not need to perform this step on installed clients.

 

Video License Requirements

The Video application requires the following licenses:

  • Base Video License (sbt_gms_vid_base)
  • Number of embedded cameras (sbt_gms_vid_embed_src), handled by management-system clients only.
    OR
    Number of external cameras (sbt_gms_vid_extern_src), also handled by VMS clients
  • Number of monitors (sbt_gms_vid_sinks)

NOTE: Cameras that are disabled in the VMS do not count toward the license totals.

NOTICE

Disabled cameras performance

Cameras disabled in the VMS are still acquired into the Desigo CC Video Configurator tab. In deployments with a high number of disabled cameras, this may impact on system performance, resulting in slower alignment or refresh.
