user5540: I am looking into a motorized tripod head to use with a standard camcorder and am wondering what people normally do for zoom?
The camera I am using is a Canon HF R56. (I am not interested in the CT-V1)

user3592: Cameras which support external control of zoom, focus, and iris normally have a port for this purpose.  LANC is the most common, but it appears that your camera doesn't have a LANC port.  According to the documentation to which you linked, the camera supports "remote control & streaming" via WiFi.  If it is at all possible to control your camera's zoom remotely, then it seems that WiFi would be the most likely method.
