An apparatus for detecting smoke in a monitored area includes: (a) a means for capturing a series of successive video images of the monitored area as a series of two-dimensional bitmaps having a specified number of pixels, (b) a means for examining this series of bitmaps to identify areas in successive bitmaps of adjacent pixels that have the potential for being used as indicators for the existence of smoke in the monitored area, (c) a means for storing these identified areas from the bitmaps, (d) a means for associating, on the basis of the likelihood of the existence of smoke in the monitored area, the identified areas from successive bitmaps so as to form a cluster of overlapping regions within those bitmaps, and (d) a means for analyzing the identified areas so as to identify the temporal changes in these areas which are indicative of the presence of smoke.
