There is provided an imaging apparatus including an imaging unit that captures a moving image and a communication unit that performs wireless communication. The imaging apparatus further includes a control unit that controls an imaging function and a transmission function for transmitting an image signal indicating a captured image that has been captured, on the basis of a time setting set in advance. The control unit at least controls switching between a standby state where the imaging function is not working and an operating state where the imaging function is working, based on the time setting.
