Abstract
A system and method is provided for an intrusion detection system. The intrusion detection system comprises a first camera configured to acquire first visual images of a monitored area and a second camera configured to acquire second visual images of the monitored area. The intrusion detection system also comprises a detection device configured to compare the first images with a background image of the monitored area. The detection device can mark differences between the first images and the background image as a potential intruder. The intrusion detection system further comprises a tracking device configured to evaluate each of the first images relative to each of the second images to determine three-dimensional characteristics associated with the potential intruder.
