An apparatus comprising an infrared (IR) illuminator, an interface and a processor. The IR illuminator may comprise an array of emitters divided into a plurality of segments each configured to generate an amount of an IR light. The interface may be configured to receive pixel data comprising the IR light. The processor may be configured to process the pixel data arranged as video frames, extract IR illumination data for each of a plurality of zones of the video frames, perform a comparison of the IR illumination data in each zone to an exposure threshold, and generate a control signal in response to the comparison. Each zone may correspond to a subsection of the video frames associated with a respective one of the segments. The control signal may be configured to independently adjust the amount of the IR light generated by each of the segments for each of the zones.
