What do you use for security in your home? We unfortunately had an expensive package stolen from us, pawned, got it back and then the criminal approached me at my house yesterday when I was home alone with the girls. He lives 2 houses down. We are really looking to amp up our home security since I'm home alone a lot. We were looking into SimpliSafe because of the great reviews but may want something in addition to that.

What do you use? Alarm system? Cameras? A dog? Something else?
