A monitoring system is provided and includes a camera attached to a train car that takes an image of the vicinity of a door of the car, where a monitor displays a camera image taken by the camera and a dirt detection unit executes a dirt detection process for detecting dirt on the front glass of the camera. This configuration thereby allows the dirt detection unit to determine the execution timing for a dirt detection process on the basis of the train information that indicates the operational state of the train to execute the dirt detection process by using the camera image that has been obtained according to the execution timing.
