My company is looking to deploy an outdoor camera processing system. The only connection available between the field and lab is wireless and this is not suitable for transmitting camera images. Instead we will set up the cameras and outdoor computers on a LAN. This will be a stationary system. All of the outdoor hardware I have seen is to do with rugged laptops (doesn't suit our needs), or rugged pcs (intended to be installed in vehicles, not as a stationary all year outdoor system).
My question is: what options are there for outdoor computer hardware. Ideally there will be one weatherproof cabinet that houses a computer rack with multiple server PCs and a switch.
The other option I see is to have each PC be weather proof. Something like this: http://www.tomshardware.com/news/computex-2006-vission-iceman-outdoor-pc,2908.html
However that PC is for home entertainment.
