The green connector is DC12V, it should have +/- marks. The other two wires must be AC24V.
The cable with the video connector; that is for when you are mounting the camera in place, it will have a video connector inside. That way you can connect a small screen to it to adjust the camera positioning, OSD Menus, etc.
Edit: No, wait... I guess you had not bothered looking at the manual, neither did I. the green connector is for both DC12V and AC24V. The orange/white wires are for RS485, for controlling the OSD menus remotely.
Thanks, called the company and confirmed
