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.

First claim

The invention claimed is:

1. A method, comprising:
receiving, at a remote security system, one or more respective inputs from one or more sensors in an environment, wherein the remote security system is a cloud-based system performing a monitoring service and is operating in a first mode;
generating an occupancy estimate for the environment based on the one or more received inputs and an occupancy model;
determining a second mode, wherein:
the determining is based on the occupancy estimate and one or more mode rules that associate occupancy estimates with modes of the remote security system,
the second mode is different from the first mode, and
each of the first mode and the second mode is independently selected from the group consisting of: an armed mode, a disarmed mode, a combination mode, a stay mode, a home mode, a night mode, a vacation mode, and an away mode; and

changing, automatically and in response to the determining, the mode of the remote security system to the second mode.

2. The method of claim 1 , wherein the changing the mode of the security system further comprises determining that the mode rules permit the automatic mode change.

3. The method of claim 2 , further comprising, after changing the mode of the security system to the second mode, sending a notification of the mode change to a computing device associated with a user.

4. The method of claim 3 , further comprising:
receiving, at the remote security system, an override indication from the computing device associated with a user; and
performing the changing the mode of the remote security system in response to the receiving the override indication.

5. The method of claim 1 , wherein the automatically changing the mode of the security system further comprises:
determining that the mode rules do not permit an automatic mode change of the security system;
sending a mode change request to at least one computing device associated with a user; and
receiving a response to the mode change request authorizing the mode change.

6. The method of claim 5 , wherein the at least one computing device associated with the user is a personal computing device or a speaker system.

7. The method of claim 5 , wherein the user is a resident of the environment.

8. The method of claim 7 , wherein the user has most recently left or is expected to arrive at the environment when the environment is unoccupied.

9. The method of claim 5 , further comprising, when the one or more mode rules do not permit an automatic mode change for the security system:
receiving, at the remote security system, a delay period from the computing device associated with the user; and
waiting the length of the delay period before changing the mode of the remote security system to the second mode, when the response authorizes a mode change.

10. The method of claim 1 , wherein the occupancy model comprises a set of machine learning weights configured to be used with a machine learning system.

11. The method of claim 10 , wherein:
the machine learning system is trained to estimate the occupancy of the environment using at least one of supervised training, unsupervised training, online training, or offline training; and
the occupancy model encodes a model of the occupancy of the environment based on the one or more inputs received from the one or more sensors.

12. The method of claim 1 , wherein the one or more mode rules are either parameter-based rules or conditional-clause based rules.

13. The method of claim 1 , wherein the occupancy estimate comprises an indication of one or more of:
a number and an identity of occupants in the environment;
whether the occupants are residents, known guests, or unknown;
a number of pets in the environment;
locations of occupants and pets within the environment;
whether any occupants have recently entered or exited the environment;
whether any occupants are expected to enter or exit the environment in the near future; or
a length of time an occupant who is a resident has been present in or absent from the environment.

14. The method of claim 1 , wherein the determining further comprises matching the occupancy estimate to one of the one or more mode rules.

15. The method of claim 14 , wherein the matching uses one of a best match or an exact match.

16. The method of claim 1 , wherein the changing the mode of the security system further comprises transmitting an output configured to change a state of at least one of:
one of the one or more sensors; or
a control.

17. The method of claim 16 , wherein the changing the state of one of the one or more sensors comprises one of:
placing the sensor in an armed state from a disarmed state; or
placing the sensor in a disarmed state from an armed state.

18. The method of claim 16 , wherein a state of the control is changed, the control is a lock, and the changing the state of the control comprises one of:
placing the lock in a locked state from an unlocked state; or
placing the lock in an unlocked state from a locked state.

19. The method of claim 1 , wherein, when the security system is in the combination mode:
at least one of the one or more sensors is in an armed state, and
at least one of the one or more sensors is in a disarmed state.

20. The method of claim 1 , further comprising filtering, before generating the occupancy estimate, the one or more received inputs to remove received inputs which are not related to the determining the occupancy of the environment.

21. The method of claim 1 , wherein the one or more inputs comprise a time of day.

22. An apparatus, comprising:
a remote security system configured to:
operate in a first mode;
receive one or more respective inputs from one or more sensors configured to monitor a respective aspect of an environment, wherein the remote security system is a cloud-based system configured to perform a monitoring service;
generate an occupancy estimate for the environment based on the one or more received inputs and an occupancy model;
determine a second mode, wherein:
the determining is based on the occupancy estimate and one or more mode rules that associate occupancy estimates with modes of the remote security system,
the second mode is different from the first mode, and
each of the first mode and the second mode is independently selected from the group consisting of: an armed mode, a disarmed mode, a combination mode, a stay mode, a home mode, a night mode, a vacation mode, and an away mode; and

change, automatically and in response to the determining, the mode of the remote security system to the second mode.

23. The system of claim 22 , wherein the remote security system is further configured to determine that the mode rules permit the mode change.

24. The system of claim 23 , wherein the remote security system is further configured to send, after changing the mode of the security system, a notification of the mode change to the second mode to a computing device associated with a user.

25. The system of claim 24 , wherein the remote security system is further configured to:
receive, at the remote security system, an override indication from the computing device associated with a user; and
perform the changing the mode of the remote security system in response to the receiving the override indication.

26. The system of claim 22 , wherein the remote security system is further configure
