Applying DVR is not suitable as all the camera is IP based, unless we get a NVR but very expensive. They are viewing through Internet, not through LAN. That's why it troubles me a lot. I am planning to get 7 PCs for 4 internet lines, each PC views 16 cameras. How do you think? Some of them said getting 2 servers to handle 100 cameras, 2 broadband lines.
However, I wonder how would the speed is if each server handles 50 cameras, some more they want to do recording.
