Have you considered (hold your ears BI fans) other software? Find your way to my profile here and check the home page. Click on CAMNET. One license covers a lot. Say 10,000 cameras on 1,000 servers, if you could put that in your house. Business? A bit more for a single location, but still, a single, fixed price. And still less than what you pay for elec. (for a month, I'd say) to run what you have.
Details are there, in about 50 pages. If you don't like it from that you can avoid installing.
