Tax and Revenue Management: A government’s lifeblood
IT has provided the opportunities for governments to remodel the entire process of tax collection over the last decade. It is, however, a continuously evolving process and governments the world over need to constantly upgrade their tax systems to optimise their revenue workflows.
Unlocking Public Value
A recent SAP study confirmed that those organisations which adopt best practices in the areas of scope and adoption, process standardisation, technology and customer governance, do perform better, and do so as their best practice maturity increases.
Governments and Socialising
The advent of social media has seen governments hopping onto the bandwagon in a bid to further engage citizens.

Environmental interference to security
As sophisticated security threats continue to rise, environmental factors have become a key issue impacting organisation’s ability to prevent and detect crime. FutureGov spoke to Mr Yoshikazu Hirano, General Manager - Security Solutions Asia Pacific, Sony Electronics Asia Pacific, about the technologies in high definition (HD) surveillance cameras that address these challenges.
“Security cameras need to capture videos in extreme lighting conditions due to 24 hours video feed. It is a constant challenge to have higher resolution and clear images in poor light conditions – which affects the usability of images as forensic evidence whenever required,” says Mr Yoshikazu Hirano.
Visibility
Image quality, noise reduction and motion blur need to be taken into account when governing organisations’ security systems. Superior picture quality in Sony surveillance cameras can be attributed to innovations such as View-DR and Exmor™ CMOS sensors. “View-DR is used in our new HD cameras to produce images with an extremely wide dynamic range and nearly doubles the sensitivity compared to conventional Wide-D technologies,” adds Mr Hirano. Dark areas - where details can be lost in shadows - are brightened considerably and bright spaces are toned down in the image to create a balanced, high contrast image. This technology elevates surveillance systems to forensic grade image quality for identification.
The Exmor™ CMOS sensor was adopted because of its highspeed readout characteristics to capture multiple HD resolution images at very high speed. During the process of combining multiple images, the Visibility Enhancer (VE) is employed to provide a high level of chrominance and luminance – and as a result, the monitored images become very visible.
In the case of night time and outdoor surveillance monitoring, the eXcellent Dynamic Noise Reduction (XDNR) selectively uses 2D and 3D noise reduction methods to provide clear images for both moving objects and still portions of the image to minimise unwanted motion-blur. Sony’s latest range of HD video security cameras complies with the Society of Motion Picture and Television Engineers (SMPTE) video industry standards, ensuring the provision of excellent balance of image resolution, image monitoring, transmission and storage. “Videos can be viewed in their original resolution on Standard HD format widescreen (16:9) video monitors to avoid scaling, aspect ratio distortion, and the pillar-box on the slides of the screen,” Yoshikazu explains.
Analytics
Sony HD video security employs robust detection methods through smart analytics within the camera to maximise the efficiency of the monitoring system. For example, false alarms can be reduced or removed using the Intelligent Motion Detection (IMD). This smart detection solution reviews the past 15 video frames and compare these with the current video frame to eliminate random movement such as trees, shadow or rain. This helps to free up back-end resources, which are usually used to generate and filter analytics.
Along with tamper alarm and audio detection, rulesbased processing is also being used to minimise server workload, network bandwidth, and storage requirements. The Distributed Enhanced Processing Architecture (DEPA) Advanced is a combined function of the camera intelligence and the rules or filters on the recorder or software to determine what is to be recorded or when to trigger an alarm.

Actually the first thing came up to my mind after reading this article that there is a solution for any problem that anyone can face.
A lot of security solutions companies offer many solutions but are these solutions can really help me in my problem?. what you really need to do is to weigh the pros and cons of your situation and then pick the most convenient security solution.
Intelligent Motion Detection (IMD), Dynamic Noise Reduction (XDNR) and Visibility Enhancer (VE) are important features to be existed in the security solution that you are planning to choose because these features can deal with many circumstances which would be faced.
Sony Delivered many convenient solutions in the this article and i believe that Sony is a pioneer in IT and its nothing new that Sony delivers perfect solutions.
