Person's behavior monitoring device and person's behavior monitoring system

A person's behavior monitoring system, comprising:

• a plurality of cameras installed in a facility;
• a server device that acquires captured images of the plurality of cameras through a network to generate a monitoring image;
• and
• a display device that displays the monitoring image output from the server device,
• wherein the server device includes
• a processor for acquiring the captured image of each of the plurality of cameras, acquiring information relating to a person requiring special attention by analyzing the captured image, and generating the monitoring image including the information, and
• wherein the processor
• determines, for each of the plurality of cameras, whether or not a person detected from the captured image is a long-time stayer who stays continuously for a predetermined period of time or longer in a capturing area of one of the plurality of cameras based on a result of tracking the person,
• generates the monitoring image in which a fixed form image that enables identification of a degree of stay is superimposed on the captured image in correspondence with the person corresponding to the long-time stayer,
• determines whether or not the person who is determined as the long-time stayer is same as a past long-time stayer who has been determined as the long-time stayer in the past and detected to have left the capturing area of the one of the plurality of cameras in the past, and
• in response to determining that the person who is determined as the long-time stayer is the same as the past long-time stayer, changes a display mode of the fixed form image.
