What is the Wide Dynamic Range(WDR) technology?

Wide Dynamic Range(WDR) Technology uses two shutter speeds in alternative video fields,  high and normal, and combines these two fields into one frame. It allows every detail to be captured accurately even if one portion is bright while other portions are dark. As a result, combined fields yield a frame of high quality images. Below is a comparison of camera technologies with its video images of Regular, Backlight Compensation (BLC), and Wide Dynamic Range.

What is fps?

The fps stands for frames per second. i.e. number of video frames shown on screen per second. A human visual to the motion pictures as live depends on the speed of the frames shown, the larger number of fps means more frames on screen per second. There are standards for the films, typical ones are:

The NTSC standard: 30 fps.
