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 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 Client
The configuration client 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.
Configuration Client
Playback Client
The playback client takes advantage of Bosch's powerful
and flexible VideoSDK. Advanced playback capabilities
include trick replay with variable-speed forward/reverse
play, video export to file, replay of video from file, as well
as playback from Bosch video encoders and the
VIDOS‑NVR.
VRM 2.10 supports two alternative ways of replaying video
data: either by directly connecting the playback client to
the iSCSI disk arrays or through the VRM Server. When
using the direct replay each playback client consumes one
iSCSI session per iSCSI target and provides up to 32
simultaneous camera replay sessions.
When replay is done through the VRM, only the VRM
consumes one iSCSI session per iSCSI target and delivers
up to 32 simultaneous camera replay sessions. The
camera replay sessions can be increased by the secondary
VRM server. The playback client does not consume iSCSI
sessions.
The playback client supports synchronized replay of up to
four camera streams.
The playback client also provides fast and flexible image
retrieval based on block-based motion detection,
metadata search, and forensic Video Content Analysis
(VCA).
Note Video export and VCA Forensic Search
require a separate license.
