My security strategy for our home is simple: Motion detectors and a bunch of huge freaking sirens. If someone enters when the system is on, the sirens will go off so loud that it is physically difficult to stay in the house. And of course thieves will need to worry about neighbors being alerted to the noise. (It also sends out SMSes, but I rely completely on it running off intruders well before they get to steal anything or anyone has to intervene.)
