  1. A dvr I've used with MPEG4 uses @12-15Kbps per frame. That means for 7.5fps you'll need at least 90Kbps, and for 19 cameras that comes out to at least 1710Kbps. First, I would get the most upload that you can from your ISP, after knowing how much you got then you tweak the fps and quality.

     

    It is a H.263 MPEG4 DVR with a 100:1 compression ratio. File size per frame is 16kbps/frame, meaning 7.5fps x (16kbps/frame)= 120kbps. This is only for one camera, 19 cameras is 2280kbps for upload! How far away? Maybe wireless better option.


  2. Here are some links,

    I was more interested in the bullet type outdoor WZ-14, -16. An outdoor bullet with those specs like the day-night, resolution, the vari-focal, I think one is 24V, and the IP outdoor rating make it appealing, plus the price. I'll check Speco and Nuvico, those WZ's look like a roll of the dice.
