Hello Ibby: Lucky man to have all that horse power available. IP cameras are really good and for the cost generally more capable than analogue cams but one does need the always on system to record motion or action. During the days I experimented with IP cameras, I have decided to go analogue for my own in house system with DVR, I discovered Blue Iris software, This is just a great package and will allow you to display IP cameras AND analogue cameras from any DVR at the same time, Blue Iris does require a little extra horsepower from your system. Mine is a 16 gbyte, Win 7, 3.5 gig htz AMD four processor CPU and it runs blue Iris displaying 16 cameras (4 IP 12 Analogue from 2 different DVRs) with motion detect on all and full frame count recording. The CPU loading is around 18%, memory loading is about 12% and network loading is at 16%. My LAN is a full gigabit LAN. The advantage of having a DVR system as well as IP cameras is that the DVR keeps running longer during a power failure if on UPS than a full system so you still have some security protection.

If there are main sections of the building where connections between them will only be available during this redo then install plastic conduit between the sections. Absolute minimum ID of 1" recommend 1.5". It will always be there to add through in the future.
