Abstract
Systems, apparatuses, and methods for determining a security status are described. Magnetic fields may be detected by sensors that are positioned to determine the location of a magnet. The location of the magnet may be used to determine the configuration of an object to which the magnet is attached. The use of multiple sensors may be used to detect null regions of magnetic fields that may not be detected by one of the sensors. Further, potential malfunctions in the sensors may be determined automatically.
