A palmcorder is a small camcorder, one which fits in the palm of your hand.
Get the Panasonic Palmcorder PV-L454 Camcorder.
You cannot use a Firewire with this Camcorder
All I needed was a USB cable that will fit into the DV outlet on the camera. The camera came with a USB cable that fits into the outlet labeled TO PC, but this only works with PCs, not Macs, so I needed to buy a USB cable that fit into the outlet labeled DV. Then, it worked like a dream. I'm using a Panasonic Palmcorder miniDV Web Camera, Model No PV-DV2020D.
