Abstract: Systems and techniques are provided for automatic security system mode selection. A set of signals may be received from sensors distributed in an environment with a security system. The security system may be in a first mode. An occupancy model may be received. An occupancy estimate may be generated for the environment based on the set of signals from the sensors and the occupancy model. Mode rules may be received. The mode rules associate occupancy estimates with modes of the security system. A second mode for the security system may be determined based on the occupancy estimate and mode rules. The second mode may be different from the first mode. The mode of the security system may be automatically changed from the first mode to the second mode.

Abstract: A security system includes a plurality of sensors installed at a premises to capture data from an environment in or around the premises, a memory configured to store data captured spanning at least a first period of time, and a processor configured to arm the plurality of sensors in an order determined based on a history of detected activity in the premises as indicated by the stored data.

Abstract: Systems and techniques are provided for security system re-arming. Input invoking restricted credentials may be received. The security system of an environment may be changed from a first mode to a second mode based on the restricted credentials. The restricted credentials used to change the security system to the second mode may be determined to be near expiration based on an expiration condition of the restricted credentials. A notification may be sent to a person associated with the restricted credentials including a reminder to use the restricted credentials to change the security system to the first mode before the restricted credentials expire.

Abstract: A method includes detecting, with a passive infrared sensor (PIR), a level of infrared radiation in a field of view (FOV) of the PIR, generating a signal based on detected levels over a period of time, the signal having values that exhibit a change in the detected levels, extracting a local feature from a sample of the signal, wherein the local feature indicates a probability that a human in the FOV caused the change in the detected levels, extracting a global feature from the sample of the signal, wherein the global feature indicates a probability that an environmental radiation source caused the change in the detected levels, determining a score based on the local feature and the global feature, and determining that a human motion has been detected in the FOV based on the score.

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.

Abstract: In a method for detection of an anomaly related to information about a location of a mobile computing device, the anomaly related to the information about the location of the mobile computing device can be detected by a processor of the mobile computing device. A communication about the anomaly can be provided via a user interface of the mobile computing device. The anomaly can be caused by a bug in an operating system of the mobile computing device. Notifications about the anomaly can be provided to a user of the mobile computing device or other mobile computing devices registered to a shared account.
