The Power of
DSP Chipset Technology Samsung has a reputation for producing some of the finest surveillance products in the world. One of the major reasons for this is attributed to the company’s ongoing investment and development of DSP chipsets that form the core technology of its cameras and domes. In this article, Peter Ainsworth, Senior European Product Manager for Samsung Techwin Europe Ltd., highlights some of the technological advances introduced by Samsung to ensure users achieve maximum benefits from their investment in a surveillance system. There is a large diversity of reasons why surveillance cameras are used and an equally large number of different environments where cameras may physically be installed. Recognising that trying to pack every possible function onto a single DSP chipset is not economical or practical, Samsung’s design engineers have developed a series of chipsets each

with a set of functions to provide the optimum solution for specific types of applications and projects. The individual Samsung DSP chipsets each sit at the core of their own specifically developed range of cameras and domes. Users are able to take full advantage therefore of the unique features of each of the chipsets, whilst being able to choose the perfect camera model for the job at hand.
There are currently four Samsung DSP chipsets to choose from:
W-5 DSP Chipset Cameras equipped with the W-5 chipset have the ability to capture superb quality colour images at up to 600 TV lines colour resolution plus the following innovative functionality: Samsung Super Noise Reduction (SSNR) technology - The W-5 DSP chipset features the thirdgeneration of Samsung Super Noise Reduction
technology (SSNRIII) and is able to eliminate image noise in low-light conditions without creating ghosting or blurring. There is also the added bonus that this amazing technology can save up to 70% hard disk space on a digital video recorder, whilst maximising bandwidth when viewing the video over a network. Coaxial control – Multi-language on screen menus can now be accessed either locally or remotely set up from the comfort of the control room via a coaxial control cable. Coaxial control allows both video and telemetry to be transmitted via the coaxial cable, giving full access to camera set-up and pan-tiltzoom functions via a compatible digital video recorder. The technology offers the potential of real cost savings through the reduction of cabling infrastructure, whilst providing flexibility for retrofit applications by allowing existing equipment to be upgraded quickly and easily. Super Dynamic Range (SSDR) automatically lightens the dark areas within a scene whilst maintaining the brighter areas at the same level. This ensures that the dark areas become more visible allowing the operator to ‘view’ objects in the shadows. Highlight Compensation technology identifies areas of peak white, i.e. excessively bright areas, in the image and neutralises it by inverting them to black/grey. This enables the camera to effectively see past these areas allowing the operator to view previously hidden details. Digital Image Stabilisation (DIS) technology that can negate the effects of the camera shaking due to high winds or building vibration.
