Claim security...

Ok, just finished building my stone fence yesterday. What a chore that was!
I've been reading about adding torch posts and braziers to also increase security. What do those things do? I checked this morning and if I put a single torch post in the very middle of my fenced in area it will completely cover my entire claim with room left over.
Is 1 enough or should I add more, perhaps, 1 in each corner?
EDIT: I've been looking for the thread that goes into detail about claim security. Think it was titled something like "Secure your $*#%" or something like that. Can someone link it for me?
