Claim:
1. A method comprising: examining a switch and saving an indicator that an animal is present or not present within a secured area; detecting a moving object within the secured area; determining a size of the moving object; determining that the size exceeds a predetermined size threshold value associated with the animal; determining an aspect ratio of the moving object; determining that the aspect ratio meets a predetermined aspect ratio threshold value associated with the animal or a crawling human, but not an upright human; retrieving the indicator from memory that establishes whether the animal is present or not present within the secured area; analyzing the moving object to determine if the moving object is the animal when the indicator indicates that the animal is not present in the secured area; and setting an alarm upon detecting that the moving object exceeds the predetermined size threshold value, that the aspect ratio meets the predetermined aspect ratio threshold value associated with the animal or the crawling human, and that the indicator establishes that the animal is not present in the secured area.
