Get the audible alarm if you can (ADT).It's so loud and painful that it will drive them out of the house.Ive managed to set off a friends alarm a time or two 

Are audible alarms illegal where you live?
As you say, police response is not necessary, but a decision based on availability and priority. This is what I'm driving at. Like I said, alarms are great, but not the whole answer.
I know people who believe they are safe because they have a gun. Even though they've never shot that gun and really have no idea how to defend themselves. I also know people who don't lock their doors because they have an alarm system. Yes, that's right, it's not just criminals who are stupid. And that's what I'm driving at. You still have to lock your doors and secure your valuables.
I'm glad that you responded with gusto to every alarm call you had. I'm also glad you caught several bad guys.
I'm moving into a new apartment in August and I'm thinking of having a wireless ADT security system installed as protection for when I am not home. The apartment isn't in a bad neighborhood or anything (it's a college town), I just like knowing that I have the extra security. I think I'm a little paranoid ever since my brother had his apartment burglarized a few years ago but luckily insurance replaced all of his belongings. Does anyone have any opinions/experiences with ADT or similar security system companies?
