Samsung Techwin Cut through the noise
Samsung Techwin have laid claim to a major CCTV technological break through to overcome a long standing problem for the electronic security industry. The effect of noise reducing the quality of video images when CCTV cameras are operating under low light levels has been a cause for concern for some time.
Samsung Techwins new Super Noise Reduction (SSNR) technology has provided the solution. Technically it dramatically reduces both random and fixed noise and at the same time produces a high signal to noise ratio and no ghost effect.
So how do these technical innovations translate into tangible benefits to end-users?
In simple terms the result is clear sharp images, even in the most severe lighting conditions. The substantial reduction in noise means that the best quality images are available to security personnel to both observe and record as evidence.

The absence of any ghost affect, that is normally quite common in low light conditions, offers a higher level of identification - a big plus where, for example, there is a requirement to recognise number plates.

A major additional benefit of the technology is the greatly reduced file size of recorded images. SSNR has the positive effect of reducing an images file size by a mighty 70% when using the MPEG format and by 40% when using a JPEG format. This offers an immediate financial benefit i.e. when recording and storing images onto a digital video recorder, a far smaller hard disc is required

This really is a case of seeing is believing, said Simon Shawley, Samsungs UK Sales Manager. We recently demonstrated SSNR for the first time at the IFSEC 2004 exhibition. To do so we created a dark room to be able to show a comparison between standard cameras operating with and without SSNR. The results impressed all those that visited our stand
Samsung have so far introduced SSNR into four of their Wide Dynamic Range day/night cameras.
The SSNR technology will benefit virtually any CCTV projects Schools, Hospitals, Airports, Car Parks, etc. In the near future we plan to incorporate SSNR into all our cameras in our range.
Samsung are one of the worlds largest manufacturers with their consumer and industrial divisions offering a diverse range of products from television, PCs, mobile telephones and digital camera to helicopters and tanks. Samsung Techwin is the division that concentrates on CCTV products. All products have been designed, developed and built by people who know what is required by installation engineers and end-users alike
