BVMS - Technical Essentials VRM – What happens before recording can start ? Bosch IP Camera 1. VRM checks and formats the available storage on iSCSI targets 2. VRM assigns multiple storage blocks (list) to camera LAN communication VRM Server 17 iSCSI Recording 3. Afterwards the camera can start to record on the assigned iSCSI storage blocks (by default continuous recording takes place) iSCSI Storage Building Technologies | BT-VS/MKK1 | June 2021 © Robert Bosch GmbH 2018.

BVMS - Technical Essentials VRM facts. One VRM server does the following Manages the cameras: up to 2000 Provides blocks to the cameras Make sure enough blocks are given to the cameras for independent recording up to 7 days Manages the storage: up to 4 Petabyte of storage (net capacity) up to 120 iSCSI storage targets (recommended 40) Manages the recording bandwidth: Balances automatically the video stream load of the cameras across the different iSCSI storage targets Uses the available storage most efficiently VRM offers flexibility and scalability: Easy expansion of cameras and storage in the system 19 Building Technologies | BT-VS/MKK1 | June 2021 © Robert Bosch GmbH 2018.

BVMS - Technical Essentials Bosch VRM versus Recording servers from other vendors Other VMS Vendors (not Bosch) use any kind of recording servers: What does it look like ? What are the main differences ? Rec. Server 1 Rec. Server 2 Rec Server 2 …… Rec. Server x 20 Building Technologies | BT-VS/MKK1 | June 2021 © Robert Bosch GmbH 2018. All rights reserved, also regarding any disposal, exploitation, reproduction, editing, distribution, as well as in the event of applications for industrial property rights. BVMS - Technical Essentials Other VMS: Recording servers concepts (non Bosch) 1/2 1. Rec. pulls the Video from the camera 2. Rec. Server pushes the video to the storage Rec. Server 1 LAN Rec. Server 2 Rec. Server 3 3. Live video is Rec. : pulled from Rec. Server Fixed assignment of cameras to a dedicated Rec. Server (assumption: no multicast network) Bandwidth and number of camera are limited on each Rec. Server Why? Because the video stream passes the Rec. server for recording (+live) Live View Client Not expandable: more cameras mean more Rec. Servers Higher initial investment because more servers are required Storage capacity is fixed by allocation to one Rec. Server, no flexible sharing of storage on demand 21 Building Technologies | BT-VS/MKK1 | June 2021 © Robert Bosch GmbH 2018.

BVMS - Technical Essentials Other VMS: Recording server concepts (non Bosch) 2/2 Rec. Server 1 Standby 1 Rec. Server 2 Standby 2 Rec. : A single point of failure (sits always between camera & storage system) Server redundancy feature to be ordered on top: N+1 redundancy: Invest in one more server One additional Rec. Server HW “waits” in hot or cold standby When one active Rec. Server fails the additional Rec. Server can take over N+N redundancy: Invest in double amount of servers Higher operational costs for all servers: Operating systems, HW to maintain, etc. 22 Building Technologies | BT-VS/MKK1 | June 2021 © Robert Bosch GmbH 2018.

Why? The camera remembers the location on the iSCSI storage of the last 32 blocks of recordings BVMS: An outstanding VMS architecture on the market! 31 Building Technologies | BT-VS/MKK1 | June 2021 © Robert Bosch GmbH 2018.
