extremeWDR

Video surveillance cameras have been developed to provide the best image quality under difficult and changing lighting environments. One of the most important aspects is the Wide Dynamic Range (WDR) or backlight correction technology, which reacts to the change of light. WDR is a technology for obtaining an excellent image by resolving the difference in brightness when the background is brighter than the main object or glare is generated by strong lighting.

Generally, WDR is required in the following situations:

• During daytime, where it is relatively dark inside a building and bright outside.
• A bright light shines towards the camera, such as with a car approaching the camera with its’ headlights turned on.

Hanwha Vision has been working continuously to strengthen its WDR function to provide optimized and vivid images in the strong backlit scenes. Hanwha Vision introduced the Wisenet7 implemented with the extreme WDR technology which can produce high resolution images suitable for forensic search application in the environment with strong backlit.

The WDR technology applied to Hanwha Vision cameras provide excellent image quality while minimizing side effects to deliver videos suitable for all applications.
