Thanks for the replies.
I am having a tough time deciding on this system:
I am trying to stay in a budget around 700.00. This is for home use. The 4 channel is probably enough, but I know how it goes I will want 1or2 more cameras and wished I had bought the 8 channel system.
It appears that they have an economy system and a step above economy in both the 4 channel and the 8 channel, what are the differences between the economy and the next level higher?
