What does the driving recorder wdr mean? Should I turn it on?

The wdr on the driving recorder refers to the wide dynamic mode. When the driving recorder is in this mode, the shooting angle can be wider and even darker places can be shot. Generally speaking, the wide dynamic mode driving recorder is a relatively good product. WDR wide dynamic range technology; WDR is called wide dynamic range, which refers to wide dynamic range. In wide dynamic mode, the image can distinguish the ratio of the brightest luminance signal value to the darkest luminance signal value, so both particularly bright and dark places in the environment can be clearly seen. Generally speaking, WDR wide dynamic technology is applied in the field of photography, which can make the imaging image have better performance and higher resolution. In the driving recorder, WDR wide dynamic technology allows it to shoot in brighter or darker places and expand the shooting range, making it more practical when driving at night. However, due to hardware facilities, the WDR wide dynamic mode of some driving recorders is invalid. Therefore, when choosing a recorder, be sure to choose a regular, well-reputed big brand recorder to prevent quality problems and unnecessary troubles after buying it.
