CCTV Camera: The Problem Solvers
  Date:2010-5-14   Browse: 1334
WDR cameras can be used for solving the most difficult situations in surveillance such as the foyer scenario.

In recent years advances in picture sensors and picture processing have led to video cameras with significantly higher performance levels. High-performance wide dynamic range cameras which can be of versatile use in this area of application have been available for a number of years. The Wide Dynamic Range (WDR) property means that the brightest and darkest areas of an image can be displayed simultaneously. We know from other branches of technology (for example, audio systems) that the performance level of an information-processing system chain is determined by the performance of its weakest element. The performance of cameras has increased enormously -- so this article is dealing with the sharpness of the lens
Is there anyone who hasn’t tried a strange pair of glasses on, just out of curiosity or for fun? Some people become glass wearers themselves.  The world looks different to them and the familiar becomes new and exciting.  Habits can change; they start reading again and move more confidently in crowds.  Surprised by this chain of events, they ask themselves, how come they previously regarded their limited perception as absolute.  Someone who has their eyes open has a new perspective.
I want to use this analogy to point to the key role of optical systems in CCTV.  In recent years advances in picture sensors and picture processing have led to video cameras with significantly higher performance levels.  High-performance wide dynamic range cameras which can be of versatile use in this area of application have been available for a number of years.  The Wide Dynamic Range (WDR) property means that the brightest and darkest areas of an image can be displayed simultaneously.  We know from other branches of technology (for example, audio systems) that the performance level of an information-processing system chain is determined by the performance of its weakest element.  The performance of cameras has increased enormously -- so this article is dealing with the sharpness of the lens.
