Seeing is believing – Hanwha Techwin America Techwin to demonstrate unique Super Noise Reduction technology

Product Profile

The SHC-721A Wide Dynamic Range Day/Night colour camera incorporates Samsung Techwin’s unique Super Noise Reduction (SSNR) technology.  When lighting levels are low, SSNR dramatically reduces both random and fixed noise and at the same time produces a high signal to noise ratio and no ghost effect.  In simple terms the result is clear sharp images, even in the most severe lighting conditions.  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 for example, to recognise number plates.

An additional benefit of this technology is the reduced file size of recorded images.  A DVR’s recorded file size is reduced by a massive 70% when using a MPEG format and by 40% when using a JPEG format.  
Other Key Features:
  • Integral ICR (Infrared Cut Filter) ensures best possible colour images during the day and
  • Maximises sensitivity to infra-red at night in monochrome mode.
  • Samsung Techwin’s Dual Automatic White Balance technology ensures a true colour image.
  • Built-in motion detection provides for the camera view can be divided into 48 detection zones.
  • SuperVision II superior back light compensation that creates two fields of each image which  are  analysed and then combined into one composite picture.  The result is ultra sharp clear images.

Additional info

Hanwha Techwin's SV II WDR technology helps to get detailed information of dark part without saturation of bright part.  There is no limitation of zone area with the perfect backlight compensation, and the color image is crisper than any other BLC functions.  It combines two fields which are high shutter speed exposure in bright areas and low shutter speed exposure in dark areas into one composite image.
