Abstract
A barrier alarm device for reducing the number of false alarms that may occur in a home security system. In one embodiment, a barrier alarm device, such as a door or window sensor, determines whether a barrier, such as a door or a window, has been opened, determines whether a human being is in proximity to the door or window inside a monitored premises. If a human being is inside the monitored premises when the door or window is opened, it indicates that the human being is authorized to be inside the monitored premises, and an alarm signal is not transmitted to a central security panel, thus reducing false alarms.
