For using Quad graphics cards, we would need a special motherboard so that each motherboard can support 2 graphics cards each.
That would mean. 2 computers, 4 graphics cards (each with 4 outputs). A total of 16 outputs, multiply it by 2 using splitters.
This is probably the best in terms of quality and value for money
Went around Sim Lim and got some good quotations as well as a feel of what exactly is available.
Graphics Card (Quad output)
ATI HD3870×2 – S$559
Leadtek Quadro NVS440 – S$899
Matrox QID LP - S$1699
PNY NVS440 – S$899
(The most expensive)
Leadtek Quadro FX3450 – S$2399
I also found some VGA to RCA converters (about $70 each but there should be a cheaper one), VGA Splitters – 1 split to 4 ($90). There are RCA splitters as well.
Detailed information on analog cameras.
A high resolution Sony CCD Camera (Dome shaped) has 2 models, one for $149 and one for $199. The most expensive one is for $500, but that is probably too high end.
We have to bear in mind that with a quad graphics card, there might be potential issues of heat buildup in the computer as well.

Viewcast Osprey-230 only BNC and s-video input
Canopus ADVC-55, or bigger.

here comes a solution with a quad video card. the 4 video outputs from one computer would need to be multiplied or split by a multiplexer or splitter to a vga or bnc/rca/composite video signal which will then feed each of the mini lcd screens.
quad video cards
(1) fireMV 2400 PCI 128MB PCI architecture, 128 MB memory, dvi-v and vga connectors. ~US$400
(2) Matrox G200 MMS Quad VGA Sgram PCI 32MB cheap but i am not sure if strong enough. ~US$120
more matrox and ati quad cards.
i tried to find an equivalent form nvidia but they seemed to be more expensive see the following overview for a lots of quad monitor video cards, with my favorite being the ati 2400 card.
an overview of multimonitor multi head video cards.
usb to vga
this usb to vga adapter looks interesting but seems a bit experimental for what we have in mind. any thoughts about this approach? (Maximum: 6 units USB 2.0 VGA adapters on one PC (not suggestion for playing, can arrange monitors in a 2 x 3 matrix found at ebay)
video splitter
a nice overview of different splitter techniques at smartvm.com.
what we would need is a dvi or vga to rca splitter. splitter here can be a multiplier of the same image of a “box” that can split an image into 4 parts and feed component video (rc or bnc).
I found this link that seems to be a better solution. It is quite similar to the previous one. Still have not received a reply from the other site, so will drop these guys an email as well. I am pretty sure these are available in Singapore, just have to scour around a bit. Once my cast is off on Friday I’ll be a bit more mobile.
adding more to the list:

I did some research on some CCTV cameras, they have some decent ones. A good budget would be at least $200 for a decent quality camera. Better quality ones would cost a bit more for sure. But what is the budget for the camera? Maybe it would be good to get the camera first before doing anything else.
Also, it might be good to get a camera that is slightly wide angled.
Any thoughts?
