Network Surveillance Server


today im going to tell you about NSR.
NSR is the device from SONY which made for the CCTV IP solution.

Overview,

The NSR series is a hard disk recording server 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 by connecting them directly to the unit

Large-capacity hard disks allow recording for long periods of time
Equipped with large-capacity hard disks, the unit is capable recording high-quality images for extended periods of time.

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-1200 can support up to 64 cameras, the NSR- 1100 can support up to 32 cameras, and the NSR-1050H can support up to 20 cameras. The NSR-1200 records images at a total frame rate of 480 fps1) (240 fps with the NSR-1100, 120 fps with the NSR-1050H) in VGA resolution (640 × 480 pixels)2) and JPEG image format (1 frame about 31 KB) for a crisp image quality.

1) 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.

2) In QuadVGA resolution (1,280 × 960), the frame rate is 1/4
that of VGA resolution.


High reliability
The NSR-1200 supports RAID 51) and peforms with high reliability. 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 uninterrupted 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. In particular, when using the unit together with
an NSRE-S200 or other expansion storage, use a UPS.


Other features
• You can display the images from up to 64 cameras (8 × 8 images) on one screen.
• The NSR is capable of manual, scheduled, and alarm recording, among others.
• The NSR is equipped with a motion detection function1(Video Motion Detection (Recorder)).
• Run searches for recorded images by camera name, date, alarm, and other methods.
• Create privacy zones by using the dynamic masking functions2). Dynamic masking covers pan, tilt, and
zoom.
• Precise alarm processing is made possible by performing the various types of filtering3) that use the image
processing results sent from the camera in the form of object information metadata. Because filtering can be
applied to metadata that has already been recorded, you can also search for areas of interest after recording is finished.
• Audio recording and playback4) are also supported from compatible cameras.

1) Some functions are limited depending on the number of cameras connected.
2) Some functions are limited depending on which camera models are connected.
3) To perform motion detection and object detection using metadata, a camera that supports motion detection by metadata is required. The use of metadata is supported for up to 32 cameras.
4) Optional audio amplifiers or speakers are required.
