1. A communication system comprising:
a first imaging device;
a communication unit including an NAD (Network Access Device) and an antenna; and
a processor,
wherein the processor is configured to:
control the communication unit to have a router function of performing a first communication in a first network environment and an external communication function of performing a second communication in a second network environment wider than the first network environment, the processor controlling the communication unit to execute the first communication with a mobile communication terminal and the second communication with a communication device other than the mobile communication terminal to execute relay communication relaying the communication between the mobile communication terminal and the communication device;
control the communication unit to transmit, via the first communication, data of a first captured image that is captured by the first imaging device to the mobile communication terminal having the first communication established for the relay communication; and
control the communication unit to transmit, to the mobile communication terminal having the first communication established for the relay communication, imaging time point notification information indicating a future imaging time point of the first imaging device and imaging instruction information for giving an instruction to execute imaging by a second imaging device provided in the mobile communication terminal at the future imaging time point.
