A method of remote control is provided. A user interface of a controlling end inputs switching control signal. A first port of the controlling end transfers the control signal to a USB connector of an image capture unit. After being handled by a processor, the control signal is transferred to at least one controlled end through a second port by a USB-C connector of the image capture unit. Thus, the controlling end connects to and communicates with the controlled end, where the controlling end operates the controlled end with the user interface. Hence, the controlling end operates the controlled end with the connection of the image capture unit without switches and network. A simple method is obtained with cost effectively reduced.
