    • Embodiments of the disclosed subject matter provide systems and methods of adaptively adjusting sensitivity of a sensor of a security system that provide a first sensor to detect a motion event of a door or window of a building, and a controller communicatively coupled to the first sensor, to determine whether the detected motion event is a human-caused motion event or a periodic motion event by a comparison between data of the detected motion event and stored motion data, and to generate a security exception when the detected motion event is determined to be a periodic motion event, where the controller adaptively adjusts a sensitivity of the first sensor to detect the motion event according to data aggregated by the first sensor over a predetermined period of time.
    • 所公开的主题的实施例提供了自适应地调整安全系统的传感器的灵敏度的系统和方法,所述安全系统的传感器提供第一传感器以检测建筑物的门或窗的运动事件,以及通信地耦合到第一传感器的控制器, 通过检测到的运动事件的数据与存储的运动数据之间的比较来确定检测到的运动事件是人为的运动事件还是周期运动事件,并且当检测到的运动事件被确定为 周期性运动事件,其中控制器根据第一传感器在预定时间段内聚合的数据自适应地调整第一传感器的灵敏度以检测运动事件。

    • In order to adjust the detection sensitivity in the detection of abnormal situations in response to conditions in a monitored location, this sensitivity adjustment device is equipped with an extraction unit and a sensitivity determination unit. With candidate location information (which indicates a candidate location, that is, a location which is close to a monitored location being monitored by the monitoring system, and is a location where an event affecting the degree of congestion of persons or vehicles may occur) used as a key, the extraction unit extracts information pertaining to an event scheduled for the candidate location from a database storing text written in regard to the event. In accordance with a predicted degree of congestion in the monitored location, which is predicted on the basis of the candidate location information and the information pertaining to the event extracted by the extraction unit, the sensitivity determination unit determines the detection sensitivity of the monitoring system in the detection of abnormal situations occurring in the monitored location.
    • 为了根据监视位置的状况来调整检测异常情况下的检测灵敏度,该灵敏度调整装置配备有提取单元和灵敏度判定单元。 使用候选位置信息(其指示候选位置,即靠近被监视系统监视的监视位置的位置,并且是影响人员或车辆的拥塞程度的事件的位置)被使用 作为密钥,提取单元从存储关于事件写入的文本的数据库中提取与针对候选位置调度的事件有关的信息。 根据基于所述候选位置信息和与所述提取单元提取的事件有关的信息预测的所述被监视位置的预测的拥塞度,所述灵敏度确定单元确定所述监视系统的检测灵敏度 检测监控位置发生的异常情况。
