WDR (Wide Dynamic Range) Function Camera The Wide Dynamic Range function of a camera is intended to provide clear images even under back light circumstances where intensity of illumination can vary excessively. The WDR allows a camera to filter the intense backlight surrounding an object and thus enhance the ability too distinguish features and shapes on the subject. When a vehicle gets out of a tunnel, a black box camera system which is pointed forward will see the background washed out during day time and is a fatal problem of the current black box system which is usingCMOS. The RVS Systems blackbox features the WDR Function Camera and solves this fatal issue.
