A method and apparatus where the apparatus performs the steps of detecting a moving object within a secured area, determining a size of the moving object, determining that the size exceeds a predetermined threshold value associated with an animal, determining an aspect ratio of the moving object, determining that the aspect ratio meets a predetermined aspect threshold value associated with an animal or crawling human, but not an upright human, retrieving an indicator from memory that establishes whether an animal is present or not present within the secured area and setting an alarm upon detecting that the moving object exceeds the predetermined size threshold, that the determined aspect ratio meets the aspect ratio of an animal or crawling human and that the indicator establishes that there is no animal present in the secured area. |
