Spec Sheet
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.
Distributed Storage
VRM not only provides for redundant management of
metadata, it also introduces a significant enhancement
of overall reliability and availability. By providing
redundancy for storage provisioning and a failover
design for the central recording management service,
there is no single point of failure. In addition, unlike
classic NVR systems, VRM scales without requiring
additional PCs. This greatly reduces the risk of system
failures.
Functions
VRM Server
VRM Server, with the central Recording Management
Service, maintains a database containing the recording
source information and a list of associated iSCSI
drives. The central monitoring includes a Web-based
user interface for status monitoring. This provides
system status overview, recording status information,
as well as for live view and recording preview for
single cameras.
VRM Server
Configuration Manager
The Configuration Manager allows for central
configuration of the network storage subsystems,
recordings (including schedules), data rate, frame
rate, stream, and privileges, as well as for managing
user accounts.
Playback Client
For replay use Bosch Video Client BVC Version 1.3.1 or
later. The BVC is available on the Bosch ST web site
www.boschsecurity.com.
For more information about Bosch Video Client BVC,
see the product specific documentation.
Integration of 3rd Party Cameras
VRM 2.22 with its new component Video Streaming
Gateway offers the option to integrate cameras that
support ONVIF, standard RTSP or JPEG protocols. The
Streaming Gateway is intended for live viewing and
VRM iSCSI based recording of cameras in low
bandwidth environments or of 3rd party cameras
supporting one of the above mentioned protocols.
Automatic Network Replenishment ANR
A VRM server can perform maximum 3 ANR jobs
simultaneously. If you configure multiple ANR jobs for
1 device (for example with 4 channels), these jobs are
performed one after the other. This avoids overload of
the device. The number of ANR jobs cannot be
increased by a secondary VRM server. The maximum
performance is 24-times of replay, the actual
performance may be limited by the capabilities of the
encoder/camera.
