We've been with ADT ever since I started travelling for work (10+ years). Honestly though I think the signs (front and backyard) and a couple window stickers are enough to disuade most thieves.

For the rare home invasion where they're looking to hurt people a security system isn't going to help. Having a gun won't help either unless you happen to be watching the Simpsons with a loaded gun in your lap.
