Abstract
Provided are systems and methods for smoke and fire detection. An example method includes receiving two or more image frames that represent images of two or more areas, combining the two or more image frames to generate a composite image frame that represents an image of an area comprising the two or more areas, comparing the composite image frame to a background frame associated with the area to determine one or more pixels of the composite frame having a pixel value that is different from corresponding pixels of the background frame, determining a smoke frame, wherein pixels of the smoke frame that correspond to the one or more pixels of the composite frame comprise a pixel value associated with smoke, determining a smoke value corresponding to pixel values of the pixels of the smoke frame, determining that the smoke value exceeds a smoke threshold value, determining a smoke or fire condition based at least in part on determining that the smoke value exceeds a smoke threshold value, and providing an indication of the smoke or fire condition.
