A camera system is configured to automatically monitor an area. Depth image(s) of the area are acquired based on active IR light emitted by the camera system and reflected from the area to a sensor array of the camera system. The depth image(s) are computer analyzed to identify a human subject. For each spectral illuminator of the camera system, spectral light image(s) of the area are acquired based on active spectral light in the spectral light sub-band of the spectral illuminator reflected from the area to the sensor array. The spectral light image(s) for the spectral illuminators are computer analyzed to identify an interaction between the human subject and an object in the area. In response to identifying the interaction between the human subject and the object in the area, an action to be performed for the object in the area is computer issued.
