Video surveillance industry is undergoing drastic improvements from time to time to give better protection facilities to the customers. WDR or the wide dynamic range is the latest improvement after the higher resolution cameras. What exactly is WDR? The camera is development such that contrasting lights are cleared out to give better picture. This mostly applies in situation where a light source passing through glass or mirror gives an aberrated picture.

When both very bright and very dark areas together come in the field of vision, the WDR proves effective to provide clear picture. This kind of intense lighted surrounding usually gives misshaped images. Measures are being taken to make WDR feature an inbuilt facility in all cameras at all times so that when such a situation is faced, the WDR in the CCTV surveillance system is automatically activated to give pictures of clarity.

All the details in the FOV are captured. Initially with the 1080p quality the customers were happy with the resulting image produced. But with the WDR the low noise, good contrast images were beyond satisfaction. This has been proven to be useful in situations where the level of incoming light cannot be predicted. The area many have different brightness levels in the field of vision area and a use of a high resolution camera with no WDR, for example in a parking lot, will give poor quality video with no face recognition and the video will be not at all useful for any purpose.

WDR facility has been narrowed down into two further classifications. Digital WDR system is controlled by software where the gamma value is adjusted automatically to better the quality of the low lighted areas. The True WDR system makes use of the double exposure method where longer and shorter exposures are used on dark and bright areas to get two or more exposures. These are then combined into a single frame picture. The resulting image quality is better than the digital WDR system.

The importance of WDR is expected to gain more acceptances with business to be used in surveillance locations in outdoor areas to cover the max area in good quality videos.
