IP Server Build Help

post #1 of 7
Thread Starter 
Hello,

I am building an IP Server for a Store, it is a small system probably 4-6 cameras but they will be at least 3mp h.264 camera running at 15fps 24hrs a day. Data backup is not a big issue considering the info will be rewritten every 30 days. I am planning on using these main components:

Xeon E3 processor
12gb 1333mhz ram (ECC)
6 2tb WD Enterprise hard-drives in Raid 0
Asus P8B-X Motherboard
Quadro 600 Graphics Card

My main question is will there be any bottlenecking here, I have built many mainstream systems but do not have too much experience with Security Camera systems. So I am not too sure if this will be able to run not only the 4-6 cameras but also more cameras in the future if needed (with more storage of course). What do you guys think?

Thank You

I haven't had much experience with that, but the one thing that stands out is the storage. Change that over to RAID 5 or 6 for safeties sake. If a drive goes down, the entire array is lost, and will cause a good bit of down time.

no need for anything but the most basic of GPUs - a Quadro ain't required. I doubt you need that much RAM or CPU either - but that will depend on the specific cameras and you'd need to check with the manufacturers. I'd never run anything like this on a RAID0 array for definite. You should also have separate OS drives in RAID1 too.

I really wouldn't build it yourself though - to be honest for security systems I'd be going to a specialist. The laws surrounding usage & storage of recorded images is a minefield - you don't won't to have a lovely clear image of a thief making off with your stuff only to have the judge rule it as inadmissible because you had the recording stored in the wrong format or your camera was pointing in slightly the wrong direction - and yes, this has happened (my partner is a lawyer).

Not to mention the fact that you want your CCTV system to be bullet-proof reliable. And no home brew system can ever be close to that.

Thank you for the responses, how many 2tb drives would I have to add to be able to achieve the same amount of physical storage if I am switching to RAID 5 and also if the drivers are in Raid 5 is enterprise necessary?

Secondly I do have the system behind 2 bulletproof areas, so that is not an issue

why dont you make it a bit easier on yourself and set it up so

They record 15FPS for 48 hours so you have two days with constant video BUT at same time record at say 5FPS.

ie once 48 hours are over the 15fps streams start at the beginning of the file again whilst the 5fps ones continue recording until 30 days is over. that way you dont need such a large amount of hard drive space

also you'd need 7 drives, 6 in use (12TB) and 1 redundant though raid 6 would be safer and require two redundants

I don't mean you need to protect it from bullets - I mean the reliability has to be as high as possible...

@OP

I agree with the_beast; for something like this you should go to a specialist, especially considering the legal ramifications.

However, if you insist on building it yourself, you could look at Western Digital's AV and AV-GP drives. They are designed for continuous, sequential recording of data, as opposed to having to deal with random access patterns of consumer and enterprise drives.

One thing to note with them: they NEED to be in a redundant RAID array (think RAID 5 or 6), since they don't bother with retrying a read or write on a bad block, they just keep on truckin'. This is important in video recording, since you don't want to miss any action.
