Another tip I can think of: Even if you don't have a security system currently, but you do have a security sign (ADT, Brinks, etc), keep it out front of your home. It *can* act as a deterrent to a criminal thinking of breaking into your home, and will give you a ready excuse to a dude like this Pinnacle character: "I already have a security monitoring service, it's serviced by (that company; eg ADT, etc) & I'm happy with their service. I have no problems with it, please leave my property immediately." Be firm with telling them to leave, if they keep saying typical telemarketer crap like "but I can save you $$", or "you will have a much better system, etc", just respond with "Leave my property now", any further response from you should include "I will call the police if you do not leave now." The last 2 will generally give them a clue that you're too smart for them or they waste their time & will not get a sale from you.
