  The present invention relates to a monitoring device that remotely monitors a monitoring section including a plurality of monitoring areas in which monitoring means such as monitoring cameras and monitoring sensors are installed.

  In recent years, a monitoring apparatus that uses a remote monitoring terminal to display monitoring images from a plurality of monitoring cameras installed in a plurality of monitoring properties and performs intensive monitoring has been used. In such a monitoring apparatus, in order to display a monitoring image, it is first necessary for the user to select a monitoring camera for which the image is to be displayed.

  Conventionally, as a method of selecting a camera in a monitoring apparatus, a method has been proposed in which a monitoring area in a monitored property is displayed as a plan view and a camera icon (camera symbol) superimposed on the plan view is selected (patent) Reference 1). In this conventional method, when a user selects a monitoring camera, first, the user selects a monitoring property for displaying a monitoring image by selecting a camera symbol displayed on the map. Next, a plan view including the position of the surveillance camera is displayed by selecting a plan view display from the menu screen. Then, by selecting a camera icon on the plan view, a surveillance camera to display an image is designated.

  With this camera selection method, you can select the desired surveillance camera while looking at the layout of the surveillance property. For users with little experience (users who are unfamiliar with the operation or who do not know the placement of surveillance cameras, etc.) The convenience was improved.
