1. A system for detecting a thermal anomaly, the system comprising: an image capturing component operable to capture a visual image of incident light in a scan area, the image capturing component further operable to capture an image having a feature, the feature having a coordinate associated with the feature in the captured image; and a radiation capturing component operable to capture a thermal image of incident radiation in the screening area, the thermal image including an analysis area that is a subset of the screening area, the analysis area based upon the coordinate of the feature captured in the captured light image.
