Abstract
An additional logic algorithm is employed in the process for reducing motion-type false alarm of security alarm system automatically or manually, wherein the preset time period of the delaying period of the verification condition is reduced to a shorter first adjusted time period when a second alarm trigger is occurred after the first alarm trigger during the preset time period. If a third alarm trigger is occurred during the first adjusted time period, the delaying period is further reduced to a second adjusted time period shorter than the first adjusted time period. The delaying period will be further reduced when subsequent alarm trigger occurred. However, if there is no third alarm trigger occurred during the first adjusted time period, or there is no subsequent alarm trigger occurred after the last alarm trigger during the latest reduced adjusted time period, the delaying period will be reset to the preset time period.
