  • Publication number: 20240121507
    Abstract: Reduction in power consumption of a video camera and a remote controller that displays a captured image of the video camera and improvement of operability are achieved. In a system including the video camera and the remote controller that displays a captured image of the video camera, when a period in which there is no operation on the operation unit of the remote controller reaches a first prescribed time, transmission of the captured image from the video camera to the remote controller via Wi-Fi communication and displaying processing on a display unit of the remote controller are stopped. Further, when a period in which there is no operation on the operation unit of the remote controller reaches a second prescribed time, the Wi-Fi communication is interrupted. Valid operation unit information in each mode is displayed on the display unit of the remote controller.
