Slim type (2U), space-saving 19-inch rack
mounting model

installed in a standard universal pitch EIA 19-inch rack.

High reliability
The NSR supports redundant configurations such as RAID
5
1)
and performs with high reliability. In a RAID 5
configuration, for example, the system can continue
functioning even if one of the hard disks develops a
malfunction. The NSR also supports uninterruptible power
supplies (UPS)
2)
, making them extremely reliable
systems.
1) RAID 5 is a system for dividing and storing data and parity
(error correcting codes) onto more than one hard disk drive.
Although this system allows continued operation should one
of the hard disks malfunction, it does not guarantee restoration
of lost data. In addition, due to high internal processing loads
during reconstruction after you replace the malfunctioned
hard disk, the unit may not be able to record images at the
configured recording rate while reconstruction is in progress.
2) If the power turns off suddenly during operation, the data may
be corrupted.
Protect data from power interruptions
If the power supply is interrupted while the unit is in
operation, data may be damaged. We recommend using an
uninterruptible power supply (UPS).
Other features
• Custom layout support allows you to display images in a
variety of different layouts in addition to standard 2 × 2
and 3 × 3 layouts.
• The NSR is capable of manual, scheduled, and alarm
recording, among others.
• Run searches for recorded images by camera name, date,
alarm, and other methods.
• Audio recording and playback
1)
are also supported from
compatible cameras.
• If a video loss occurs due to the network connection
being disrupted or an abnormal shutdown occurring,
video can be recorded to the camera’s Edge Storage,
allowing you to retrieve the data later after the system is
restored.
1) Optional audio amplifiers or speakers are required.
