PCI interfaces, on the other hand, operate only a little fast for desktop cameras. One USB port can support multiple devices together so you won't have to switch devices every time. It also saves you the cost of switch boxes and cables. Moreover, if you use USB, you don't have to reboot your computer when adding new devices. Don't worry about separate power supplies.
Power is supplied directly to the camera through the USB cable.
