I modded this article up.
Now you can mod me down.
I wanted at least one article from junk in firehose to mod up.
The article itself has not much value for me, but discussion has.
You can have surveillance system, but you must have person to watch screens.
Cameras must see every corner. If not, people will find them. Areal cameras have problem to find difference between noise (trees, flags) and moving persons. Night vision motion detection is useless, noise level is too high.
This is my experience with cameras from 2005, 2000$ each.
Today we have Cell, Tilera, FPGAs http://en.wikipedia.org/wiki/Field-programmable_gate_array at no cost, but I doubt it would be more useful than systems I know.
