1. An area monitoring system comprising:
a plurality of sensor devices each installed in a monitoring target area and configured to detect a mobile object moving in the monitoring target area; and
a determiner configured to determine whether or not mobile objects detected by the plurality of sensor devices are the same physical object,
wherein the plurality of sensor devices include at least a radio wave sensor and an optical sensor, and
wherein the determiner determines whether or not mobile objects detected by the radio wave sensor and the optical sensor are the same physical object on the basis of information of at least one of feature quantities regarding movements of the mobile objects and reflection intensities corresponding to attributes of the mobile objects when the mobile objects have been detected by the radio wave sensor and the optical sensor.
