1. A fixed retail scanner including a data reader, comprising:
a housing configured to be disposed within a checkout counter of a retail environment;
a plurality of camera modules disposed within the housing;
a plurality of illumination assemblies disposed within the housing, wherein each illumination assembly of the plurality includes:
a first sub-group of light emitting diodes (LEDs) emitting at a first wavelength; and
a second sub-group of LEDs emitting at a second wavelength and co-located with the first sub-group of LEDs on a common illumination board within its respective illumination assembly, wherein at least two illumination assemblies are connected to each other in a daisy chain arrangement; and
a system controller disposed within the housing and operably coupled with the plurality of camera modules and the plurality of illumination assemblies, and configured to activate each illumination assembly together to provide active illumination for the plurality of camera modules such that:
the first sub-group of LEDs of each illumination assembly of the plurality is activated together across the different illumination assemblies to be synchronized with a first camera module of the plurality; and
the second sub-group of LEDs of each illumination assembly of the plurality is activated together across the different illumination assemblies to be synchronized with a second camera module of the plurality at times different from the first sub-group of LEDs.
