HAS ADT SYSTEM AND WAS NOT AWARE THAT IF THE THIEF SNATCHES THE SYSTEM OF THE WALL BEFORE THE 45 SECOND DISARM TIME PERIOD THAT ADT WILL NOT GET A SIGNAL. SOMEONE BROKE INTO MY HOME AND ADT DIDN'T GET SIGNAL. THEY HAD FREE RANGE AND STOLE 20,000 WORTH OF MY POSSESSIONS. IF YOUR SYSTEM IS A FREE 3 IN 1 SYSTEM ADT IS AWARE OF THE PROBLEM AND DOES NOT CARE. THEY DON'T TELL YOU ABOUT IT. I FOUND OUT WHEN THE REPAIR MAN CAME OUT TO RESTORE THE SYSTEM. THEY ARE SCAMMING PEOPLE AND SELLING THEM A FALSE SENSE OF SECURITY. IT IS HARD TO FIND ATTORNEY'S TO FIGHT THEM, THEY HAVE PLENTY OF SCAM ATTORNEYS PAID BY THEM.
