To connect the camera to PC you will need an i.Link cable model IEEE 1394 (FireWire/i.LINK). This cable can be purchased through the Amazon/AliExpress and other major online stores.
If you don't have a Firewire port available on your computer, then you can buy an external card that connects to USB ports or simply use the built-in Memory Card slot to transfer the content to PC using a card reader.
