Next Generation Review Software (NGRS)
The Next Generation Review Software (NGRS) is the new application for data review for the safeguards systems. NGRS has been designed to support a suite of review tools using a common, intuitive user interface, capable of correlating multiple data types for a comprehensive view of all safeguards data in a secure environment from a variety of IAEA (International Atomic Energy Agency) supported systems.
Through remote communication or through physical swapping of media, safeguards files can be accessed and then reviewed on a review station equipped with NGRS. Primary functions include the safeguards data management (data loading, data security – authentication and decompression), automatic data analysis (such as trigger scans and motion detection), management of review events and generation of safeguards data review reports.
The initial version (1.0) of the software supports surveillance data from DCM-C5 (NGSS) and DCM-14 (DIS) cameras and will feel familiar to users for the General Advanced Review System (GARS). NGRS uses modern graphical interfaces that run on the Windows® 7 operating system and provide the necessary functions to read, decrypt, authenticate and analyze safeguards data. It is capable of handling very large data sets which may reside locally or on a network accessible storage space. Automated data analysis functions will alert the reviewer to any safeguards data discrepancies as defined by the user-configurable settings and will produce reports of the results of the data analysis activities.
NGRS provides significant performance improvements over its predecessor GARS. The design allows the software to automatically adapt to multiple core architectures, when available, to further improve data processing speeds. This product is intended to be a complete replacement for GARS. This initial NGRS software release (version 1.0) supports only surveillance review functions. However, future releases of NGRS will process data from other instruments and will be easily expandable to include data from other safeguards data collection devices. NGRS has been designed as a flexible, modular software application with the expectation of facilitating the addition of future safeguards applications with minimal impact on the existing functionality. This modularity applies not only to safeguards data types but to the encryption and authentication methods used to protect the data.
The NGRS GUI (Graphical User Interface) provides tools for reviewing image data, including a quad-view or single view video player, and tools for reviewing tabulated data such as event report navigation tools and histogram views of environmental and state-of-health data.
The DCM-C5 and DCM-14 camera modules each apply different data encryption methods to the surveillance data and have different meta-data formats in the file header of the MPEG-formatted image files. Therefore, separate libraries have been provided within NGRS to process surveillance data from each of these camera sources. These camera support libraries operate simultaneously within NGRS, allowing DCM-C5 and DCM-14 data to be reviewed side-by-side if desired.
The NGSR software does not interface with any other commercial software. It is intended to be a stand-alone application with the specific purpose of safeguards data review. Reports are created and stored in standard text formats for use with any program capable of displaying and editing text files. The NGSR software is a Microsoft® Windows application and will take advantage of the features and functions built into the Windows operating system, including resizing windows, file access, etc.

DCM-C5 Camera - NGSS
The DCM-C5 uses a digital CMOS image sensor with an active array of 2592 (H) x 1944 (V) pixels.
The vertical and horizontal output resolution can be adjusted in three steps:
320 x 240, 640 x 480 and 1280 x 960. At low output resolutions, sub-sampling is achieved through row and column summing which improves low-light performance. The DCM-C5 supports electronic pan, tilt and zoom (EPTZ). In this mode, the image sensor operates at maximum resolution but only certain areas of the pixel array will be used to generate an output image. Placement and size of these areas can be changed at any time. The DCM-C5 has the capability to correct the aspect distortion of images acquired with the fish-eye lens to provide clear undistorted images.
In EPTZ mode, the DCM-C5 operates as virtual multi-channel system. For each channel, the user can adjust the field-of-view and trigger sources.
