From talking with my local police and my own experience, it is not worth the money to have it monitored.
If it is a business, that is a different animal but monitoring your home, in my opinion does not do much.
Placing the stickers on your windows, the motion detectors and the audible alert will send someone running just as fast.
Hell, I moved onto my street about 5 years ago. At least, twice a week one of my neighbors house alarms go off. When we first moved in I would run outside and see if someone was breaking in, I would walk through their back yards and check to see if any windows were broken or doors ajar. Then I would stand in the street until the police showed up 15 minutes later. I live in a town where the police are awesome and that is their reaction time. If you live in a place like Jackson, I can only imagine what the reaction time, if they showed at all, would be.
My point being that 90% of house alarms are false alarms and neighbors and police know it and react like it is a false alarm.
If you are having it monitored for fire, that is a different thing entirely but to pay to have it monitored strictly against break ins is not worth the money.
