Abstract:
Systems and methods of the disclosed embodiments provide a sensor to detect a side from which a door or window is being opened, and a controller communicatively coupled to the sensor to determine the side from which the door or window is being opened, and to generate a security exception based on the determination of the side from which the door or window is being opened.
Abstract:
Systems and methods for using state machines to manage alarming states and pre-alarming states of a hazard detection system are described herein. The state machines can include one or more sensor state machines that can control the alarming states and one or more system state machines that can control the pre-alarming states. Each state machine can transition among any one of its states based on raw sensor data values, filtered sensor data values, and transition conditions. Filters may be used to transform raw sensor values into filtered values that can be used by one or more state machines. Such filters may improve accuracy of data interpretation by filtering out readings that may distort data interpretation or cause false positives. For example, smoke sensor readings may be filtered by a smoke alarm filter to mitigate presence of steam.
Abstract:
Embodiments of the disclosed subject matter provide systems and methods of adaptively adjusting sensitivity of a sensor of a security system that provide a first sensor to detect a motion event of a door or window of a building, and a controller communicatively coupled to the first sensor, to determine whether the detected motion event is a human-caused motion event or a periodic motion event by a comparison between data of the detected motion event and stored motion data, and to generate a security exception when the detected motion event is determined to be a periodic motion event, where the controller adaptively adjusts a sensitivity of the first sensor to detect the motion event according to data aggregated by the first sensor over a predetermined period of time.
Abstract:
A system is provided including a plurality of inter-connected premises management devices, each including one or more sensors that generate data about an environment, and a control device to control one or more operations of the premises management system, the control device including a movement detector. The premises management system detects an attempt by an intruder to damage the control device based on data from the movement detector indicating an abnormal movement applied to the control device, historical data obtained from the sensors, and current data obtained from the sensors.
Abstract:
A sensor package is disclosed that includes, a compass, an accelerometer, and an electromagnetic flux tag based open/close sensor. The compass may be activated by a microcontroller in response to an indication of movement detected by an accelerometer. The compass's data may be utilized to determine an orientation for the object such as a door on which the sensor package is situated. The orientation data may indicate that the door is ajar and/or that a second magnetic field is present, suggesting tampering. A notice may be dispatched to a controller for the home security system, a client device, a remote system, etc.
Abstract:
A system for analyzing a current movement of a point on a garage door can include a memory, a port, and a processor. The memory can be configured to store a profile. The profile can be produced from one or more previous movements of the point on the garage door. The port can be configured to receive, from a sensor, a signal that corresponds to the current movement of the point on the garage door. The processor can be configured to perform an analysis of the signal with respect to the profile. The processor can be configured to produce a result of the analysis.

Abstract:
Systems and techniques are provided for guided installation feedback for an opening sensor. Detected magnetic field strengths of a magnetic field created by a magnet of an opening sensor as detected by a magnetometer sensor of the opening sensor may be received over a time period. It may be determined that there has been a change in the strength of the magnetic field created by the magnet as detected by the magnetometer sensor based on the received detected magnetic field strengths. Accelerometer data from an accelerometer disposed in the magnetometer sensor may be received. It may be determined from the accelerometer data that the magnetometer sensor was not moving and positive feedback may be provided to an installer of the opening sensor, or it may be determined from the accelerometer data that the magnetometer sensor was moving and negative feedback may be provided to the installer of the opening sensor.
Abstract:
A magnet and magnetometer may be integrated into a smart home environment and allow it to be placed into an away mode of operation despite an entry point being semi-open. The disclosed implementations can detect a magnetic field strength and determine, based on the detected field strength, an approximate distance that a moveable partition is open. In some configurations, the presence of a second magnetic source can be detected. A notice may be generated based on one or more signals received from the magnetometer. The notice may be sent to a controller, a remote system, a remote device, and/or a client device as disclosed herein.
