1. A method of suppressing false alarms associated with video-based fire detection, the method comprising:

  • defining acceptable regions within a field of view of a video detector;

    associating a rule with each of the defined acceptable regions;

    acquiring video data comprised of one or more frames from the video detector;

    identifying regions within the field of view of the video detector indicative of fire based on the acquired video data;

    detecting overlap between the regions identified as indicative of fire and the defined acceptable regions; and

    applying the rule associated with the acceptable region detected to overlap with the region identified as indicative of fire to determine whether an alarm should be triggered or suppressed.
