So I don't doubt that there's a good security company out there with a good system. I'd totally recommend getting one. That said, alarms are only after the fact - I highly recommend adopting some physical and landscaping measures along with an alarm system. These measures prevent them from even trying to break into your house which is really what you're after. Alarms just mean they'll have 2 minutes vs 60.
Locks, bars, and strengthening of doors is the obvious one and some of those are desired. They're also not the most pretty things, so do some research into landscape security. Essentially things like lighting, sightlines, and prickly plants can be used to deter attempts.
A quick google found this article - it's old, but the concepts are still sound. I'm sure there's more out there.
