Chapter 1 Introduction
Control compatible cameras from remote locations
You can pan, tilt, and perform zoom operations of compatible cameras from the
NSR network. The NSR provides control of focus and bright level, and also
supports audio recording from network cameras.
* Microphones and speakers sold separately.
Compatible with analog cameras
You can monitor and record images from analog cameras when you purchase
and install an optional camera server (SNT-V704).
The network ports supporting for gigabit (1000 Base-T)
As the NSR-100/50 is equipped with three network ports, you can configure the
system so that the camera network is kept separate, preventing the camera
network data from being affected by the other network data. There is more than
enough space to receive data from multiple cameras because the three ports
support gigabit transfer rates.
The NSR-25 is equipped with one network port supporting gigabit transfer rates.
Large-capacity hard disks allow recording for long periods of time
The NSR is equipped with large-capacity hard disks. The NSR-100 can record up
to approximately 920 GB
1)
of data, the NSR-50 can record up to approximately
460 GB

of data, and the NSR-25 can record up to approximately 230GB1) of
data. For example, if you record images from 16 cameras at 1 fps
2)
(VGA, JPEG;
one frame equals about 31 KB) with the NSR-100, you can record approximately
a month’s worth of images (15 hours a day)

.
1) Includes the database capacity managed by the internal software.
2) fps: frames per second.
3) When set to RAID 0.
Slim type (2U), space-saving 19-inch rack mounting model
With the optional rack mounting kit (sold separately), the recorder can be
installed in a standard universal pitch EIA 19-inch rack.
High-resolution up to 480 fps (VGA, JPEG) recording
The NSR-100 can support up to 64 cameras, the NSR-50 can support up to 32
cameras, and the NSR-25 can support up to 20 cameras
1)
. The NSR-100 records
images at a total frame rate of 480 fps
2)
(240 fps with the NSR-50, 120 fps with
the NSR-25), VGA (640 × 480 pixels) resolution, JPEG (1 frame approx.
31 KB) image format, for a crisp image quality.
1) For cameras that support image sizes of 1,280 × 960 pixels or more, the NSR-100 can
support up to 8 cameras, and the NSR-50/NSR-25 can support up to 4 cameras.
2) Maximum frame rate when 16 cameras are connected to the recorder. Each camera
has a frame rate of approximately 30 fps. This frame rate may become less because
of fragmentation on the internal hard disks. Values are based on Sony measurements.
These values are not guaranteed, as performance may change due to the user’s
operating environment.
High reliability
The NSR-100/50 offers high reliability through:
• NSR-100: RAID 0, 1+0, and 5
• NSR-50: spanning
1)
and RAID 1
When used with a RAID 1, 1+0 or 5, the system can continue functioning even
if one of the hard disks develops a malfunction. Similarly, because the system
software and settings are stored on the internal flash memory of the NSR, if the
system software develops a malfunction, lightning-quick restoration of the
system is possible. The NSR also supports uninterruptible power supplies
(UPS)
2)
, making them extremely reliable systems.
1) Spanning: Function allowing several hard disks to be virtually seen as one.
2) Sony recommendation only.
