1. A monitoring device which is provided at a building in which an elevator is provided and which communicates with a center via an IP network, the monitoring device comprising:
circuitry
to be able to perform wireless communication in a plurality of wireless communication modes;
to select a selected wireless communication mode to be used to perform wireless communication from among the plurality of wireless communication modes on the basis of a first evaluation value indicating strength of a radio wave received by the monitoring device and a second evaluation value indicating communication quality between the monitoring device and the center;
to determine whether data indicating a state of the elevator includes voice data; and
to transmit the data indicating the state of the elevator to the center in the selected wireless communication mode, wherein
the circuitry selects the selected wireless communication mode based on a result of the determination of whether the data to be transmitted includes voice data.
