There's a recent thread about home surveillance that got me a'thinkin but I didn't want to hijack it so I'm making my own. How useful on a scale from 1 to 10 do you think a home security system is? I can't speak for anyone else's experience but my house has been broken into three separate times. Each time we had a security system armed and well... nothing happend. As far as the police could tell (automatic notification) the thieves just handled business quickly and got out. Of course, they have yet to be found and I doubt that they will be but I find myself wondering, did we really need the security system? I suppose without it, they might've gotten away with more but it doesn't seem like it's worth paying a monthly fees + equipment just to have a loud noise go off and get the police to come to your house too late to do anything. I figure it wouldn't be too difficult to rig up a surveillance and security system on your own and you wouldn't have to pay a fee just for whatever stuff you need to do so. So do you think that the monthly payments of a brand name system are worth it? Do they actually serve a purpose or are they all just for peace of mind?
