1. A master control device comprising:
a communication interface including a first communication interface and a second communication interface that is different from the first communication interface, the first communication interface is configured to interface and establish communication with a plurality of client control devices and an information processing device via a first communication link, and the second communication interface configured to interface and establish communication with a first imaging device via a second communication link,
each client control device of the plurality of client control devices is configured to control one of a plurality of imaging devices, the plurality of imaging devices excluding the first imaging device; and
an electronic processor communicatively connected to the communication interface with an internal communication bus, the electronic processor configured to
receive an initial communication from the information processing device via the communication interface,
synchronize time with the information processing device via the communication interface in response to receiving the initial communication, and
control the plurality of client control devices to perform time synchronization via the communication interface based on the time that is synchronized between the master control device and the information processing device in response to synchronizing the time between the master control device and the information processing device,
wherein the first communication link and the second communication link are separate and distinct from the internal communication bus of the master control device.
