  • Publication number: 20210280026
    Abstract: The conventional image surveillance technologies relevant to the present invention had the potential of failing in detect ion due to the intrusion duration time being set too long and thereby allowing an intruder to pass a warning line before the preset intrusion duration had elapsed. The intrusion detection device according to the present invention is provided with: a detect ion means that detects, in an image, an intrusion position in a specific region by an object that has intruded into the specific region; and a control means that associates the intrusion position with a prescribed time period, wherein the detection means outputs an alert when the object, in the image, has stayed in the specific region for the prescribed time period or longer.

  • Publication number: 20200184483
    Abstract: An acquisition unit (2020) acquires a combination of person information and transaction information for a first transaction. The person information is information representing a person who executes a transaction. The transaction information is various kinds of information regarding the transaction. A storage device (10) stores transaction information of each transaction. Using the person information of the first transaction acquired by the acquisition unit (2020), a detection unit (2040) acquires transaction information of a transaction (second transaction), which is executed by a person having a high degree of similarity with a person who executes the first transaction, from the storage device (10). The detection unit (2040) detects an abnormal transaction using the transaction information of the first transaction and the transaction information of the second transaction.
