Hardware for a high end NVR

[spdfreak]

I need to build a NVR for a 40 camera (IP cameras), 12 TB of storage, surveillance system we are installing and I am wondering about hardware specs. I typically use an AMD A8-5600 FM2 system for the smaller 12 camera systems, but the question is whether the CPU and MB chipset will have any effect on larger systems like this 40 camera job. I'm thinking that as long as it has the 6Gb SATA connections it will be fine. With 12 cameras, the systems generally just sit there recording data to the HD's and barely use any resources at all- like CPU at 4% and memory at 15-20%. With dual NIC's one card is attached to the switch that all the cameras are plugged into and the other goes out to the internet for remote viewing, etc. Anyone with experience have any advice or wisdom?

Why don't you use actual dedicated NVR machines... I would never trust a 40 camera CCTV system to consumer grade PC parts and god knows what operating system.

Cost is a big reason- a high end NVR from a typical supplier is about 6000.00... plus we are trying to learn how to do larger systems more cost effectively. When I looked at the system specs on one of these high end systems, it was nothing exotic- core I5 and an Intel MB, 8GB RAM, running Win7 pro, etc. I don't know if they use server grade HDD's or something like WD 2TB drives that are marketed for Surveillance systems.

the biggest spot where you will spend money on is drives really.
You can build the rest of the system for relatively cheap, core i5, b75/b85 board, 4-8gb ram, 512mb vid card, win7

While I have never used those ones in particular, I had tried green drives and found them too slow for access when needing to search, especially when trying to view mulitple cameras at one, not so bad for one or two

I had build a system for client recently it was almost $5000 cnd for 8x 4TB enterprise drives. This is where i would say about 75% of the cost is located
