My house was burglarized 2 days before Christmas. The burglar threw a brick through the window to get in. Neither the glass break sensor nor the motion sensor triggered the alarm. They were both positioned correctly and showed no errors in SimpliSafe's system, on the app, or during the alarm test. The alarm did not trigger until the burglar left through the front door. They had plenty of time to ransack and steal my belongings. Very unnerving.
