    100% helpful (5/5)

    The BVMS Project Checklist is an Excel-based tool which makes it easier to design a BVMS system.

    This article describes how to use the project checklist.

    Pick the attachment you need, depending on the version of BVMS you have.

    Purpose

    The BVMS Project Checklist is an Excel-based tool which makes it easier to design a BVMS system

    🛈 Approval of this checklist is in best effort as it includes a storage estimation and a Encoder CPU load estimation.
    The actual scene variations in the project will ensure that the encoder CPU load and/or estimated storage may
    be different than presented in this checklist. As a result, Bosch Security Systems cannot take any responsibility
    for the storage estimations done in this checklist.

    For BVMS Enterprise systems: each sub-systems requires it separated file.

     

    Visualization

    Validation

    The tool includes a basic validation. This is summarized in line 33 and 34. Line 33 displays the approval status overview.
    If the system is planned to be extended in the future, the number of channels is higher than 500, the number of workstations is higher than 20, the number of keyboard expansions is higher than 20, or the number of DVR expansions is higher than 20, the design needs to be checked by a Bosch BVMS (BU) expert.

    Approvals change log

    The approvals change log can be (optionally) used to track the system over longer time. It is recommended to increase the document version with every system expansion.

    The related approval number can be entered, next to the total number of cameras and workstations connected to the system.

    The comment field is free text and can be used for additional comments related to the expansion of the system.

    Pools

    The tool uses two types of pools: cameras can be pooled in groups with similar properties.

    The tool is limited to 5 camera groups.

    5.png

    For each group the type of camera can be selected, including an ONVIF camera.

    Each group of cameras can be assigned to a storage pool.

    6.png

    All camera groups can be assigned to the same storage pool, which means they will record onto the same pool of storage devices.

     

    System design steps
    The system design steps represent the steps indicated in the tool.

     

    Step-by-step guide

     

    1. Camera/Encoder selection

     

    In the first step cameras are selected and related to the camera groups.

    Bosch cameras are natively available in the tool and the bandwidth is automatically calculated based on the profiles configured in BVMS.

    Select the camera from the alphabetically sorted list. The camera platform (CPP) and the CTN is automatically filled in.

    7.png

    The available stream configurations (stream 1- stream 2) are available on the selected camera model.

    8.png

    The profile is set to balanced standard by default, but can be changed when necessary. The codec is set to h_264 by default, but can be changed when necessary.

    🛈 Only CPP7 cameras or newer are able to encoder video in H.265. Please note that BVMS can decode H.265
    video, but the recording profiles are based on H.264 encoding. If H.265 is selected the BVMS recording profiles
    need to be adjusted.

     

    If an encoding codec is not supported by a camera, this is indicated.

    2. Recording stream

     

    The recording stream configuration is used to automatically calculate the bandwidth and storage consumed by the camera.

    Select the recording stream based on the stream configuration and a supported framerate.

    Based on the selected profile the target and maximum bandwidth are automatically calculated.

    10.png

     

    3. Live stream


    The live stream is configuration is used to ensure the encoder is not overloaded. Select the live stream based on the
    stream configuration and a supported framerate.

    11.png

     

    4. Number of cameras


    The number of cameras in a group can be configured. A group name can be set optionally.

    12.png

     

    5. Bandwidth calculation


    Based on the selected profile, codec, recording stream and recording framerate the video bandwidth is automatically calculated and applied.

    There is a manual override available that is also available for ONVIF cameras and Bosch cameras that are not natively available in the tool.

    13.png

    Audio recording can be enabled optionally.

     

    6. VRM settings


    The VRM parameters (sanity check and downtime) can be adjusted when needed.

    14.png

    The VRM downtime specifies how long cameras continue to record without being assigned new blocks by the VRM.

     

    For example, 4 means the cameras will record approximately 4 days even if the VRM is down during those 4 days. In this case the VRM assigns sufficient recording blocks for 4 days to the cameras.

    The amount of how many blocks are needed for a camera are determined on the bitrate that is specified for this camera. High value increases the required storage capacity of the system.

     

    The sanity check determines how much data a camera has produced in the last days.

    Depending on the traffic the number of blocks that a camera needs to cover the downtime period is determined.

     

    6.1 Primary VRM Pool assignment

    The group of cameras is assigned to a storage pool.

    15.png

     

    6.2 Primary VRM storage calculation
    The retention time is set and an quiet time / alarm time configuration can be set (hidden by default).

    This can be used in cases in which, for example, during night time a "bit rate optimized" profile is selected while during day time a "balanced" is selected or motion recording is used.

    In these cases a manual reduction (or increase) of bandwidth consumption can be configured: the amount of hours configured in this line represents the hours per day a camera is generating a reduced amount of data.

    The video bandwidth represents the reduced (or increased) amount of data generated by the camera.
    This can be manually calculated using the Bit Rate Guide (Manual) tab.

    16.png

    The result of the camera settings on the required amount of storage is shown.

    17.png

     

    6.3 Secondary VRM pool assignment
    Optionally, the secondary (dual-recording) VRM can be configured for a number of cameras in the group. If this is needed, assign the cameras to a second storage pool.

    18.png

     

    6.4 (Hidden) Secondary VRM storage calculation
    The details of the secondary VRM storage calculation are hidden and can be visualized by expanding the "+".

    19.png

     

    6.5 VRM Pool configuration
    The VRM pool configuration shows how much storage is required for each pool.

    The iSCSI failover option is set by default. This means that at least two storage devices are required and one of those devices needs to be able to handle the entire recording performance (bandwidth).

    This minimum retention time might not be possible at this time.

    20.png

     

    7. Storage device selection

     

    Based on information entered throughout the sheet a list of appropriate storage arrays are presented for the specific pool.
    The most efficient choice (based on the calculated overhead) is presented in the cell above the selection itself. If multiple
    arrays result in the same efficiency, this is visualized as well. The number of devices required in the specific configuration
    is available, but not taken into account in the overhead calculation.

    21.png

    Additionally the required VRM hardware needs to be selected.

    22.png

     

    8. Software licenses


    Depending on the amount of cameras configured in the system a BVMS family base package is recommended.

    • The number of required camera/decoder expansions is automatically calculated based on the amount of cameras configured in the tool as well as the amount of decoders configured.
    • The number of workstations is automatically calculated based.
    • The number of dual recording expansions is automatically calculated based on the number of cameras assigned to a secondary VRM.

    9. Servers and Workstations

     

    Configure the amount and type of servers and workstations.

    24.png

     

    10. Miscellaneous

     

    Configure the amount of transcoders, decoders and additional project information.

    Optional changes

     

    • RAID level
      The RAID level of a device can be configured on the StorageDevices tab and affects all storage pools. Only the RAID levels available on the device can be selected.

    27.png

    • Global spares
      The number of global spares can be configured on the StorageDevices tab and affects all storage pools. Only if a device offers a number of global spares, these can be selected.
