And also, the card I'm referring to (most security DVR products I've seen) are not really recording from 16 cameras at a time. Only one at a time actually. Think of it as only one tuner but there are 16 channels available. Most capture cards used in security DVRs works this way. > If your chipset is bt8xx, linux is well supported even w/ v4l2. Unless of course the card is using a different interface, so even if it's using a bt8xx chipset, there are no guarantees the same V4L drivers will work. -- Gideon N.
