In addition, the material, shape, dimension, numerical value, form, number, location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  In the above embodiment, when a visitor is detected by the human sensor 25, it is determined whether or not the visitor corresponds to a suspicious person. However, the present invention is not limited to this example. For example, when the operation unit 22 of the doorbell 2 is pressed by a visitor, it may be determined whether or not the visitor corresponds to a suspicious person.

  In the above embodiment, when it is determined that the visitor is a suspicious person, the suspicious person information and the suspicious person tracking data are generated, but the present invention is not limited to this example. For a specific visitor (not a suspicious person), visitor information and visitor tracking data may be generated, and the visitor tracking data may be displayed on the information terminal 3 of a specific user. This visitor tracking data can be used, for example, for watching a child or an elderly person.

  Further, the object to be tracked is not limited to a visitor (suspicious person), and may include a delivery object. In order to reduce the number of re-delivery man-hours and costs, a service has been started in which a delivery item is placed at a front door of a delivery destination house or the like when a customer is absent (so-called “placement service”). However, in this “placement” service, there is a risk of delivery theft or loss. Therefore, by using this example to generate delivery tracking data for tracking a delivery, for example, it is possible to easily track a stolen or lost delivery.

  In the doorbell system 1 according to the above-described embodiment, the information terminal 3 associated with the resident is illustrated as an external device, and the doorbell 2 is configured as a WiFi doorbell that can wirelessly communicate with the information terminal 3.
