I’ve toyed with home security cameras since the days of the first X10 systems. First, go wired, CCTV, since wireless cameras suck. Second, buy your cameras and CCTV DVR separate. Third, I hope you are familiar with router port forwarding, etc.. to get the remote access to work.
I use the cameras and DVR below and can see my home from anywhere in the world as long as I have 3G or internet access.
I have a 1TB drive which gives me about 90 days of recording.

I am not very familiar with routers and port forwarding. looks like I got some learning to do.
