1. A camera configured to generate an infrared (IR) image and a visible light image, said camera comprising:

  • a thermal imaging part configured to register IR radiation from a first field of view,a visible light imaging part configured to register visible light from a second field of view at least partially overlapping with the first field of view, anda processing device configured to process information related to the registered IR radiation and the registered visible light,wherein the processing device is configured to compare a moving object identified in the visible light image to a moving object identified in the thermal image and to determine if they represent that same moving object,wherein the processing device is configured to further eliminate the same moving object that is detectable by the thermal imaging part and by the visible light imaging part to identify thermal-image-only moving objects; and

    wherein the processing device is further configured to distinguish moving gas from other types of thermal-image-only moving objects by rejecting thermal-image-only moving objects that have edges above an edge threshold.
