A communication device, comprising: a storage that stores a search application for using a search service for searching for a route from a place of departure to a destination and that stores a planned travel route searched for and confirmed by a user using the search application; a GPS receiver that receives a GPS signal; a communicator for communication with outside; and a controller that sets an area including the planned travel route as a target area, that performs monitoring processing for determining whether an out-of-area state has begun in which a location of the communication device as recognized based on the GPS signal falls outside the target area, a movement detector that senses movement of the communication device, and a camera, wherein, when the out-of-area state has begun, the controller makes the camera perform shooting transmits monitoring information including information indicating the location of the communication device as observed when the out-of-area state began and shot data shot by the camera via the communicator to a transmission destination previously registered by the user, after transmitting the monitoring information, the controller shifts to a lock mode in which the controller limits use of the communication device, in the lock mode, when the controller detects that the communication device has been moved based on an output of the movement detector, the controller makes the camera perform shooting, acquires shot data shot by the camera when the communication device was moved, recognizes the location of the communication device as observed when the communication device was moved and transmits monitoring information including the so acquired shot data and the so recognized location via the communicator to the transmission destination. a storage that stores a search application for using a search service for searching for a route from a place of departure to a destination and that stores a planned travel route searched for and confirmed by a user using the search application; a GPS receiver that receives a GPS signal; a communicator for communication with outside; and a controller that sets an area including the planned travel route as a target area, that performs monitoring processing for determining whether an out-of-area state has begun in which a location of the communication device as recognized based on the GPS signal falls outside the target area, that sets an area including the planned travel route as a target area, that performs monitoring processing for determining whether an out-of-area state has begun in which a location of the communication device as recognized based on the GPS signal falls outside the target area, a movement detector that senses movement of the communication device, and a camera, wherein, when the out-of-area state has begun, the controller makes the camera perform shooting transmits monitoring information including information indicating the location of the communication device as observed when the out-of-area state began and shot data shot by the camera via the communicator to a transmission destination previously registered by the user, after transmitting the monitoring information, the controller shifts to a lock mode in which the controller limits use of the communication device, in the lock mode, when the controller detects that the communication device has been moved based on an output of the movement detector, the controller makes the camera perform shooting, acquires shot data shot by the camera when the communication device was moved, recognizes the location of the communication device as observed when the communication device was moved and transmits monitoring information including the so acquired shot data and the so recognized location via the communicator to the transmission destination. makes the camera perform shooting, acquires shot data shot by the camera when the communication device was moved, recognizes the location of the communication device as observed when the communication device was moved and transmits monitoring information including the so acquired shot data and the so recognized location via the communicator to the transmission destination.
