In this video we use a Canon M50 Mark II and we text all cables used for this camera model.
From it will go 2 wires: 1 to the USB port of the booth. It is responsible for allowing the camera to be controlled from your device. For Canon M50 we use micro USB- USB cable 1 m (3,2 ft).
It would be the same as if we connected the camera directly.
The second wire is the power cable with the fake battery. You wouldn't want to change the batteries in the camera in the middle of an event.
This way, you can power the camera from an outlet (located inside the booth).
