... I thought a 2TB recorder would record for a long time? I am actually planning on adding a couple of cameras or lets say I was to add 4 more cameras inside/outside the house, what would be the best way to do that, 4 individual CAT 5 cables, one to each camera? My NVR is 8 channels, it was just came with 4 cameras.
There are a number of things that will effect how much storage space is required.
Resolution, Frame Rate, Picture Quality, how many hours per day are you recording, etc - but it all controlled by the maximum bitrate. I am not sure your camera has that setting, but check to see if it does and what is it?
There are a number of online calculators out there - here is one that uses the more common settings I mentioned

Here is a chart that shows some bitrates

Hikvision has some a program you can download that uses the bitrate

So this is my next best alternative..
