1. A monitoring system comprising:

  • one or more monitoring terminals each connected to a sensor and a camera providing sensor information and image data, respectively, on a monitored region, the monitoring terminals each sampling and transmitting the sensor information at first and second intervals, respectively, the second interval being longer than the first interval;

    a client receiving the sensor information and the image data and displaying a state of the monitored region; and

    a storage server storing the sensor information and the image data, wherein;

    said monitoring terminals, said client, and said storage server are connected via a network; and

    said monitoring terminals each comprise;

    a parameter management part storing a parameter for the second interval;

    an abnormality detection part detecting an abnormal event by comparing a value of the sampled sensor information with a threshold; and

    a data amount restriction part changing the second interval when said abnormality detection part detects the sampled sensor information as the abnormal event, and starting the transmission of the sampled sensor information to said client at the changed second interval.
