1. A sensor system adapted to be installed in a monitoring device, comprising:
a first sensor configured to detect, with first light, a state of a first area that is located outside the monitoring device, and to output first detecting information corresponding to the state of the first area;
a second sensor configured to detect, with second light, a state of a second area that is located outside the monitoring device and at least partially overlaps with the first area, and to output second detecting information corresponding to the state of the second area;
a cover covering at least one of the first sensor and the second sensor while forming a part of an outer face of the monitoring device, and configured to allow passage of at least one of the first light and the second light; and
a control device configured to detect an abnormality of the cover based on an inconsistency between the first detecting information and the second detecting information that are outputted for an area where the first area and the second area are overlapping with each other,
wherein the first sensor and the second sensor are disposed in a chamber at least a part of which is defined by the cover.
