Abstract
Monitoring a premises may comprise receiving signals from a plurality of devices. One or more spatially static devices of the plurality of devices may be determined based on strengths of the received signals. A user activity pattern may be determined based on changes in strengths of signals received from the spatially static devices. Abnormal user activity may be determined based on the user activity pattern and a strength of at least one signal received from at least one of the spatially static devices.
Claims20
A method comprising:
- determining first strengths of a plurality of wireless communication signals received from a plurality of spatially static devices located at a premises;
- determining, based at least in part on the first strengths of the plurality of wireless communication signals, a group of devices of the plurality of spatially static devices that are located in an area of the premises;
- determining, based on one or more changes, during a first time period, of second strengths of wireless communication signals associated with the group of devices, a pattern associated with user activity in the area of the premises;
- and
- determining, based on the pattern and based on third strengths of wireless communication signals associated with the group of devices within a second time period, abnormal user activity in the area of the premises.

A method comprising:
- receiving, from a plurality of devices at a premises, first wireless communication signals;
- determining, based on first strengths associated with the first wireless communication signals, a first group of spatially static devices of the plurality of devices associated with a first area of the premises;
- determining, based on the first strengths, a second group of spatially static devices of the plurality of devices associated with a second area of the premises;
- determining, based on changes in second strengths of second wireless communication signals received from the first group of spatially static devices and the second group of spatially static devices within a first time period, a user activity pattern;
- and
- determining, based on the user activity pattern and third strengths of third wireless communication signals received from at least one of the first group of spatially static devices or from at least one of the second group of spatially static devices during a second time period, abnormal user activity.

A system comprising:
- a plurality of spatially static devices located at a premises;
- and a computing device configured to:
- determine first strengths of a plurality of wireless communication signals received from the plurality of spatially static devices;
- determine, based at least in part on the first strengths of the plurality of wireless communication signals, a group of devices of the plurality of spatially static devices that are located in an area of the premises;
- determine, based on one or more changes, during a first time period, of second strengths of wireless communication signals associated with the group of devices, a pattern associated with user activity in the area of the premises;
- and determine, based on the pattern and based on third strengths of wireless communication signals associated with the group of devices received within a second time period, abnormal user activity in the area of the premises.
