What is WDR stands for in security cameras?
WDR stands for Wide Dynamic Range. This function makes sure that all parts of the captured area are detailed, no matter if they are in the light/sun or dark/shade. For example, a camera is mounted inside your building pointing to an entrance gate, the difference in light can be huge. Old cameras without WDR will concentrate on the darker inside or the lighter outside. With WDR, both areas are detailed.
