Presuming you got the originally included accessories... you got the AV cable. If you didn't get the cable, you need to buy one - likely direct from Sharp.

The other item you need is an analog/digital bridge like those from Canopus or Pinnacle Systems. The Canopus units are preferred because they transfer video via FireWire - which means you will need an available, operational, FireWire port on your computer, too.... and you should have a LOT of available hard drive space on your computer for the video when it is transferred...

The camera plugs into one side of the AV cable. The other side of the AV cable goes into the analog/digital bridge. The bridge plugs into your computer.
