Patent attributes
A monitoring system includes: a monitoring device that outputs a warning when detecting abnormality of a monitoring target person in an interior of a vehicle; a housing arranged on a surface on the interior side of a roof of the vehicle; and a release operation unit arranged being exposed to an outer face of the housing, the release operation unit being able to receive an input of a warning release operation. The monitoring device, in a state of outputting the warning, releases the warning when the warning release operation is input to the release operation unit. As a result, the monitoring system can appropriately monitor the monitoring target person in the interior of the vehicle.
