JayCrash450,
The heart of the system is the PC Witness Pro V/RT Hybrid NVR/DVR as seen here.

Note this in the description: "...you can then mesh up to 16 DVRs so that they may be simultaneously monitored from an off-site location via the Internet" I had two old computers upgraded with memory and installed commercial hard drives and I have one at my office and one at my parents house, recording at those locations. I can also view my home from either place as well. However this is not part of the $1900 cost of the 'brains'.
For my analog camera I chose one of these:

I bought two of these:

And for my side door, one of these. I favor this one. Good lighting (IR), excellent picture and not in your face like my other ones. My next camera or two will be this model; one looking over my cars and one by the front door.

In the essence of full disclosure, I did purchase my system from cctvwholesalers but I do not work for them nor do I earn a referral fee, points or anything like that. For me, the money I spent is not 'chump change' and I wanted technical questions answered like bit rate, compression ratios, advantage of cat5e over cat6, smartphone access, etc. I also gave them pics and measurements of my driveway, side yards, back yard, available light, desired camera coverage area, and they ensured the cameras would do what I asked. Finally, they oversee project NOLA.

Some points I learned along the way: First, in darkness, analog tends to show better than IP unless you flood the area with IR (infrared) but with the technology developing as it is, IP cams will catch up and surpass analog, thus saving your 'brains' thus your pocketbook having the need to process both. Second, standard hard drives are not the same as commercial hard drives. Commercial hard drives are designed to run non-stop week after week, month after month. You pay more but it is necessary.
Any more questions JayCrash450, let me know.
Forgot to mention, I did my own installation.
