How much Bandwidth should I have?

I am setting up an internet connection so that someone can have remote access onto one of these 8-channel DVRs. They intend to control and monitor the DVR over the internet. Currently they have dial-on access. I don't believe Dial-on will be adequate and I want to get them a high speed connection. The problem is I don't know how much of a high speed connection they need.

Recommendations? What requirements would you give to your ISP if you wanted to remotely connect and monitor one of these things?

Thanks!

Ok, if you have 8 FPS, compressed with Mpeg4, at a resolution 720x480 with all 8 channels going at once, you'll need a 6meg connection. 8 FPS is low, and typical for CCTV cameras, if your feeds are black/white and not color, you could get by with less. That is if all feeds are being sent over the wire at once, one at a time, 800k. Look for mpeg4 bandwidth calculator. If your feed is TV, the FPS in the USA is 24, and adds more bandwidth. These are not real world numbers, but you can get an idea by dividing the size of a file by the length of the file. If a file is 60 minutes long, and 700megs = 194k per second. So record some of these feeds, see how long they are, and their size...
