Hello chokatella & welcome to MacosX
Not knowing the type/brand of cam you have, I can offer that it's likely you would either need:
- 6 to 6 pin Firewire cable
- 4 to 6 pin Firewire cable
You should be able to determine this by examining the Firewire port on your cam, it'll either be a 4 or a 6 pin connector.
Check any manual that came with the cam and you can try Googling your Cams brand name/specifications to find out info about the accessories ... the Firewire cable specs should be mentioned ....
Depending on where you live, you can pick one up fairly cheaply at either Dick Smith or Wallmart ....or similar type business
