• When placing the unit on a floor or other surface, 
make sure that the unit is equipped with the specified 
rubber feet, and put the unit down carefully. If there 
are no feet, mount the rubber feet first. Do not place 
the unit near other devices that may become a source 
of vibrations.
Wait for 30 seconds after turning power off
For a brief interval after the power is turned off, the 
platters inside the HDD will still keep spinning and the 
heads will be in an insecure position. During this 
interval, the unit is more susceptible to shocks and 
vibrations than during normal operation. For a period of 
at least 30 seconds after turning power off, avoid 
subjecting the unit even to very light shocks. After this 
period, the hard disk will be fully stopped and the unit 
can be manipulated.
Temperature and humidity related precautions
Use and store the unit only in locations where the 
specified temperature and humidity ranges are not 
exceeded.
Temperature range for operation: +5 to +40 ºC 
(+41 to +104 ºF)
Humidity range for operation: 20 to 80% relative 
humidity (maximum wet-bulb temperature 30 ºC/
86 ºF, no condensation)
Temperature range for storage: –20 to +60 ºC 
(–4 to +140 ºF)
Humidity range for storage: 20 to 90% relative 
humidity (maximum wet-bulb temperature 40 ºC/
104 ºF, no condensation)
When HDD seems to be faulty
Even if the HDD is showing signs of malfunction, be 
sure to observe all the above precautions. This will 
prevent further damage from occurring until the problem 
can be diagnosed and corrected.
HDD replacement
The HDD, fan, and battery of the unit are consumable 
parts that will need periodic replacement. When 
operating at room temperature, a normal replacement 
cycle will be about two to three years. However, this 
represents only a general guideline and does not imply 
that the life expectancy of these parts is guaranteed. 
Regarding parts replacement, consult your supplier.
Overview
The NSR series is a hard disk recorder for network 
cameras. The NSR allows you to monitor and record 
network camera images (JPEG or MPEG-4). It also 
allows you to play back the recorded images and search 
through it, making the NSR a truly versatile monitoring 
system.
Control compatible cameras from remote 
locations
You can pan, tilt, and perform zoom operations of 
compatible cameras. 
Compatible with analog cameras
You can monitor and record images from analog 
cameras when you purchase and install an optional 
camera server (SNT-V704).
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
1)
 of 
data, and the NSR-25 can record up to approximately 230 
GB
1)
 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)
3)
 
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 unit 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. The NSR-100 records images 
at a total frame rate of 480 fps* (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.
* 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.
