I am looking for a multi-input video capture card for a 6 analog camera surveillance system. I have found one from www.ituner.com called the Spectra 8, but am not sure there is an OS X driver for it (the description on the site mentions Mac support in one sentence, but nowhere else). I am wondering if anybody has tried this card before, or can recommend other multi-input video capture cards. Any recommendation or advice is greatly appreciated. Thanks in advance.
