ABSTRACT:
Wide area camera vision systems can respond to variations in light beams projected into a region being monitored. The variations are indicative of the presence of smoke in the region. In addition to providing viewable images of the region being monitored, analysis software can be used to evaluate the extent of smoke in the region or regions being monitored.
