and, when the vehicle is intended to be parked, generating information related to a parking form that makes the radio wave intensity not lower than a predetermined intensity, based on the information related to the radio wave intensity received by the communication section. ## Claims ### Claim 1 A vehicle surveillance system in which when a vehicle including a communicator that performs transmission-reception of radio communication is parked, information related to surveillance of the vehicle acquired at the vehicle is transmitted from the communicator through the radio communication, the vehicle surveillance system comprising a processor programmed to: acquire information related to radio wave intensity received by the communicator; when the vehicle is intended to be parked, generate information indicating a parking form that makes the radio wave intensity not lower than a predetermined intensity, based on the information related to the radio wave intensity received by the communicator; and when the radio wave intensity received by the communicator shows a tendency to decrease while the vehicle is moving in a predetermined area where the vehicle is allowed to be parked, generate the information indicating the parking form that makes the radio wave intensity not lower than the predetermined intensity in a different direction from a moving direction of the vehicle. ### Claim 2 (depends on 1) The vehicle surveillance system according to claim 1, wherein the processor is programmed to generate the information indicating the parking form that makes the radio wave intensity not lower than the predetermined intensity, based on image data shot by a camera included in the vehicle. ### Claim 3 (depends on 2) The vehicle surveillance system according to claim 2, further comprising a storage that stores the information indicating the parking form that makes the radio wave intensity not lower than the predetermined intensity in a predetermined area where the vehicle is allowed to be parked, wherein the processor is programmed to generate the information indicating the parking form that makes the radio wave intensity not lower than the predetermined intensity, based on the image data shot by the camera and the information stored in the storage. ### Claim 4 (depends on 1) The vehicle surveillance system according to claim 1, wherein the processor is programmed to generate the information indicating the parking form that makes the radio wave intensity not lower than the predetermined intensity, as information that a navigation system included in the vehicle provides to a user. ### Claim 5 (depends on 1) The vehicle surveillance system according to claim 1, wherein the processor is programmed to generate the information indicating the parking form that makes the radio wave intensity not lower than the predetermined intensity, by being triggered by a current location of the vehicle entering an area related to a parking area. ### Claim 6 A vehicle surveillance method in which when a vehicle including a communicator that performs transmission-reception of radio communication is parked, information related to surveillance of the vehicle acquired at the vehicle is transmitted from the communicator through the radio communication, the vehicle surveillance method comprising: by a computer, acquiring information related to radio wave intensity received by the communicator; when the vehicle is intended to be parked, generating information indicating a parking form that makes the radio wave intensity not lower than a predetermined intensity, based on the information related to the radio wave intensity received by the communicator; and when the radio wave intensity received by the communicator shows a tendency to decrease while the vehicle is moving in a predetermined area where the vehicle is allowed to be parked, generate the information indicating the parking form that makes the radio wave intensity not lower than the redetermined intensity in a different direction from a moving direction of the vehicle. ### Claim 7 (depends on 1) The vehicle surveillance system according to claim 1, wherein the parking form is a location at which the vehicle is to be parked or a direction in which the vehicle is to be parked. ### Claim 8 (depends on 1) The vehicle surveillance system according to claim 1, wherein when a plurality of parking stalls exist, the information indicating the parking form is generated such that which stall the vehicle is to be parked is able to be determined. ### Claim 9 (depends on 1) The vehicle surveillance system according to claim 1, wherein when a possibility exists that the radio wave intensity varies depending on a direction of the vehicle even in a same parking stall, the information indicating the parking form is generated such that whether the vehicle is to be moved forward and parked, or is to be moved backward and parked is able to be determined. ### Claim 10 (depends on 1) The vehicle surveillance system according to claim 1, wherein when a possibility exists that the radio wave intensity varies depending on a location in a parking stall even in a same stall, the information indicating the parking form is generated such that which location in the parking stall the vehicle is to be parked is able to be determined.
