server for large installation

[nagano 0]

Hi,

 

i'm looking for solution that would do nice in my company. want to buy 52 * 4 mp sanyo ip cameras, but still don't know what kind of server do i need. some companies who install cctv says i will need 3 separate servers, and some says that 1 will do just fine.

 

thanks for any hints

 

-------

- 5-8 fps, motion activated

- they will be used for watching how employees work and for surroundings of factory ( so not all of them, cams, will be working at full resolution )

- from calculations, i will need around 16-24 TB space for recordings

- network connected by 1Gb fiber thru 3com 2900 switches

Any decent 2 socket Intel xeon Nehalem processors, 6-8 1TB SAS drives with a raid controller and the most important, a 4 port ethernet card. Dell or Sun/Oracle are the low end, HP is the high end, most reliable. Sun/Oracle does make unique servers that allow more drives, like 16 which gets you away from external storage which is not as fast.

 

The key thing is that you seperate the cameras out into 4 seperate networks, each one with a 16 port PoE managed switch. Link up the 4 networks into each ethernet port on the server.

 

Don't know much about Sanyo, but on Mobotix, they provide a low resolution image to the software for multiple camera monitor, but record events in 3MP mode. If there's a way to do that with Sanyo, it would help reduce bandwidth.

This system adds automatic redundancy and expandability.

Before you even start to think about servers you need to decide on your frame rate from each camera, the resolution of the images and how long you intend to store the images (may be different for each camera depending on the operational requirement).

 

Then consider how you are going to deal with time synchronisation, security and redundancy.

 

Consider spare parts, operating software and how you are going to deal with bulk disk replacement at the end of year three, power consumption, power conditioning and cooling.

 

Only then should you be thinking about which server to use

QFT. Your question is like asking "what kind of car do I need" without first answering what you need it FOR.

If chosing the right PC is hard, consider this, get the cheapest PC you can find, spending over $400 is a waste. Then get a really good monitor, maybe 30".

 

Then get a camera system that does not need a PC, like Mobotix. These camera can write directly to a NAS. I use $169 1TB NAS drives, and put 2-3 camera per NAS or you can get a higher end NAS and have more cameras write to it. Since the computer is not doing the recording, you need not worry about PC or network capacity. To me, designing the proper network to manage these camera will be much harder than deciding on if you should get three inexpensive $2,000 servers, or one $6,000 server and the network will end up costing you more than the servers anyway.
