TECHNICAL SPECIFICATIONS
As with any system, maintenance is an important and vital part of
sustained operation. The NSM5200 incorporates various innovations
to make maintenance more efficient and to allow the system to
continue operating at peak performance levels. Easy access to hard
disk drives and the CompactFlash card is available from the front
panel. A unique rail system allows access to a failed fan should it
need to be replaced. Temperature sensors throughout the chassis
detect possible air-flow obstruction or clogged intake filters. The use
of enterprise-class SAS
®
technology provides advanced enclosure
management and monitoring. Notifications of potential or actual
issues are transmitted to the specified user interfaces for action.
Storage capacity is scaled using third-party storage arrays with an
optional fibre channel interface.
Software Built for Flexibility, Reliability, Cost
Optimization
In addition to unique strains placed on hardware components,
surveillance applications also demand innovations in software.
Recording software must accommodate automatic failover should a
catastrophic failure occur. Recording software must deal with file
fragmentation caused by overwrite, locking of video clips, and
managing metadata associated with alarms and events. Finally,
recording software must deal with the escalating cost of storage by
finding innovative ways to manage recorded content. This ensures
that the user extracts the most value from the cost of the storage
subsystem.
The NSM5200 supports the pooling of multiple recorders to provide
for automatic retention balancing and failover. Up to six NSM5200
nodes can be placed into the same storage pool. One of the
NSM5200s in the pool acts as the master and manages the
assignment of incoming streams, health monitoring, and
redistribution of the recording load. Should a unit fail, the given
streams are automatically redistributed to the remaining units in the
storage pool. When the failed unit is brought back on line, the
recording load is redistributed to balance the video retention period
across the recording pool. This capability also allows users to
dynamically add additional storage to a pool as their retention needs
change. Single NSM5200s can be monitored by another NSM5200 or
an entire storage pool when the single NSM5200 cannot be
incorporated into a standard storage pool.
For mission-critical applications where business continuity is
essential, the NSM5200 supports redundant recording. Independent
schedules can be created on both the primary and redundant storage
pools to ensure that the most vital data is duplicated across physical
boundaries.
The NSM5200 incorporates an improved version of Pelco’s patented
EnduraStor™ storage optimization technology. EnduraStor was
developed to manage the cost of storing high resolution, high-frame
rate video by leveraging the fact that the value of recorded video is
typically higher immediately following an incident. Organizations are
capable of specifying a desired delay period during which all
recorded video will be kept at 30 images per second (25 ips for PAL).
As the age of video available on hard disk drives exceeds the delay
period, it is automatically groomed to a lower frame rate, thus
freeing up storage capacity for new data. The NSM5200
incorporates advancements in the EnduraStor algorithm, which gives
administrators the option of classifying the priority level of alarm or
event video to retain the full frame rate.
The NSM5200 is built upon the proven stability and robustness of its
Linux®-based operating system. It utilizes an XFS file system and
automated defragmentation routines to keep the database from
becoming fragmented. XFS has been proven to be a superior file
format for the rigors of surveillance recording applications than an
NTFS file system, which is standard with Windows®-based
recorders.
The NSM5200 incorporates a number of diagnostic monitoring
functions that serve vital roles in notifying operators of potential
problems and failures. Integrated diagnostics utilize on-board LED
indicators to display warnings and failures on the NSM5200 and
then it reports these failures to operators. The NSM5200 monitors
and provides warning messages for items such as retention time
issues, accumulation of software errors, network errors that result in
packet loss, and changes to network link speeds. It also monitors and
reports hardware diagnostics such as temperatures approaching
established thresholds, hard disk drive failures, fan failures, power
supply failures, or when a stream or a NSM5200 is off line. Finally,
the NSM5200 can communicate to an APC Smart-UPS® series
uninterruptible power supply to provide battery status information
and initiate a graceful shutdown if the available charge falls below
its designated threshold.
