The Value of Wide Dynamic Range Security Cameras

Wide Dynamic Range is a technology utilized by security cameras in order to balance out images that have a large dynamic range.  An example of this situation would be if an indoor security camera were pointing towards a window or building entrance.  During daytime, the image produced by the camera would be extremely washed out due to the high brightness of the incoming light.  This effect is commonly seen in restaurants, stores, offices, and other buildings that have large windows or entrances.

In order to solve this problem, many security cameras have been using back light compensation, or (BLC), to help compensate for high brightness.  However, Wide Dynamic Range technology has recently become the most popular solution to washed out images.  WDR cameras are fitted with two Charge-Coupled Devices (CCD), one high speed and the other low speed, which are designed to take multiple scans of the same image.  The image processor will then process and combine the two images to provide one clear and balanced image which shows both the indoor and outdoor image clearly.

The prices of WDR security cameras have recently dropped to affordable levels. Several government facilities, banks, and progressive businesses are so convinced about the value of wide dynamic range technology they have incorporated WDR cameras in all of their recent security installations.

Like the early adopters, I’m sold on WDR cameras and they rise to the top of my recommendation list for customers looking to get the best insurance should crime occur.

    The WDR feature is starting to become standard on analog cameras. Some of the new Effio cameras already have the WDR technology on the cameras.
