video capture devices

I work offshore doing the hurricane recovery of the damage rigs. We work with the divers who of course do all of the work. My question is that the divers have live feed from their helmets. I want to capture some video from it. Depending on the dive company some will burn DVDs and some have it piped into a black video box. I know that you can use a video capturing device and that there are different means to plug into the box to get the video. It appears to just be plug and not fire wire. I am not looking to make a blockbuster hit so I don't want to spend to much. I would appreciate any insight.

is it just like a normal analog video cable?


If so you will need an analog to digital converter to be able to capture it.

Hey thanks for the input. They do look just like that. Any suggestions on a device?

I assume you are using a Mac. The Canopus ADVC-110 unit works great. It will import any video source and export via firewire to imovie. Imovie recognizes it as a camcorder source. About $300. There are cheaper units available (some USB), but may not work as well.
