Abstract: Systems and techniques are provided for guided installation of an opening sensor. A strength of a magnetic field created by a magnet of an opening sensor at a location of a magnetometer sensor of the opening sensor may be determined. Feedback may be provided to an installer of the opening sensor based on the determined strength of the magnetic field. A function of the opening sensor may be configured based on the determined strength of the magnetic field. The function may be associated with reporting the status of an entry point to which the magnetometer sensor may be affixed.

Abstract: Systems and methods are provided for determining, at a controller of a device of a premises management system having a head unit and a backplate, at least a partial removal of the head unit from the backplate based on a position of a removal switch that detects connectivity between the head unit and the backplate. When the controller determines that the position of the removal switch is in an open position, an orientation of the head unit may be continuously determined based on an output signal from an accelerometer coupled to the head unit. A tampering signal is output based on the open position of the backplate removal switch and the determined orientation of the head unit.
