Features
▶ Distributed storage and configurable load balancing
▶ iSCSI disk array failover for extra reliability
▶ Used with all Bosch Video-over-IP cameras and

▶ Configuration support for all Bosch disk arrays (DVA

Bosch Video Recording Manager (VRM) provides a
Distributed Network Video Recorder solution, eliminating
the need for dedicated NVRs and signaling the second
generation of IP network video recording. VRM supports
iSCSI-based storage systems and Bosch Video-over-IP
devices (IP cameras and IP video encoders).
VRM introduces the concept of a storage virtualization
layer. This abstraction layer enables VRM to manage all of
the individual disk arrays in the entire system as a single
“virtual” common pool of storage, which is intelligently
allocated as needed.
VRM eliminates the need for Network Video Recorders
(NVRs) and their associated server hardware, operating
systems, and anti-virus software, as well as the ongoing
software patches and updates these systems require.
This new technology makes installation, operation, and
maintenance much easier while reducing the total cost of
ownership.

System Overview
The Video Recording Manager is comprised of the

•

Recording Management Service (VRM Server)

•

configuration client (VRM Configurator)

•

playback client (Archive Player)

The central Recording Management Service runs as a
service on Microsoft Windows platforms. Bosch
recommends running VRM Server on a dedicated server/
hardware platform.
VRM offers system-wide recording, monitoring, and
management of Bosch iSCSI storage, video encoders, and
cameras.
VRM software supports Bosch H.264 and MPEG‑4 IP video
devices including all encoders, Dinion and FlexiDome IP
cameras, as well as AutoDome and Extreme IP cameras.
Supported storage subsystems include the Bosch iSCSI-
based DVA and DSA Series disk array systems. The iSCSI
disk arrays can be attached anywhere on a standard IP
network.
VRM 2.10 offers additional redundancy and data
availability by supporting Automatic Network
Replenishment (ANR) with Bosch Video-over-IP devices
(BVIP Firmware 4.0 or later required).
Optimal Performance
The Video Recording Manager offers a high-performance,
flexible, scalable, and a highly reliable iSCSI storage
management solution.
Optimized performance is obtained by the use of
intelligent addressing on a block level, which also allows
for load balancing of the video recording to all available
storage blocks located on any storage array in the system.
Load balancing is provided with respect to the bandwidth
and the number of iSCSI connections and is configurable
per IP address (iSCSI target).
Logical Virtualization
The VRM virtualization layer allows the scalability of
storage beyond the physical limits of a single storage
subsystem. This logical abstraction layer means that each
camera can use any storage space it actually needs, rather
than an allocated, arbitrary, discrete chunk ahead of time.
Adjust retention times of video data as required.
Fast Recording and Retrieval
VRM provides fast and flexible retrieval via a search
database of recordings and metadata. Metadata is a form
of data that describes other data such as events, ATM/
POS information, and video content analysis data. The
metadata is recorded with the video data and provides a
fast and efficient way for the search engine, in the
playback client, to quickly locate specified video clips. The
database also keeps track of the location of recording
blocks. If this database is lost, VRM can recreate the
database by reading the stored metadata, thus providing a
self-healing capability.
