1. An alert system comprising:
an external-environment camera configured to capture images outside of a vehicle;
a vehicle sensor configured to detect an operation of the vehicle that is performed when an occupant gets in or when the occupant gets out of the vehicle;
an actuator configured to change a direction of the external-environment camera to at least one of a downward direction and a backward direction in response to the vehicle sensor detecting the operation of the vehicle;
a determiner configured to determine whether a child is likely to have been left in the vehicle based on a change in the images from one of a presence state and an absence state of the occupant or an object outside the vehicle in a first image of the images to another of the presence state and the absence state of the occupant or the object in a second image of the images; and
an alert controller configured to output an alert in a case where the child is likely to have been left in the vehicle.
