Video In and viewing over the internet

So at work we have a video camera system. When we installed it, I put tuner cards in the two computers so that we could watch the cameras on the computers in the office. Everything works just fine. Now, I’d like to find a way to watch it from home. Does anyone know how I’d go about doing that? It’s not a webcam, so it doesn’t have a million programs on the internet meant for doing just that. I was thinking of using Remote Desktop, but I can’t quite figure out how to get that to work yet (although I’ve only tried that once, and it seems to be considerably more difficult when it’s only one person and the computers are 20 miles apart). Does anybody have any ideas on how I could accomplish this. FYI the computer at work has XP home and my computer has XP pro.

I once tried to change the input for my web broadcast software (Yahoo) from the webcam input to my TV tuner card. My friend saw nothing and my computer locked up. I did get remote desktop to work and tried firing up my TV viewer. My friend only saw a blue screen. Probably because the card “overlays” the video on the screen. I then tried to play an MPG file in Windows media player. A bust, all he could see was about 1 frame every 15-20 seconds. It must be possible though. I have heard of daycares setting up security cameras so parents can check in on their kids via a web site broadcasting the images. This sounds expensive.
