•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 locationsYou 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 GB1) of data, the NSR-50 can record up to approximately 460 GB1) of data, and the NSR-25 can record up to approximately 230 GB1) of data. For example, if you record images from 16 cameras at 1 fps2) 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.
