Internet activity, internet connectivity and nearby Wi-Fi and local network device presence monitoring sensor

A system comprising:

• one or more computers;
• and
• one or more storage devices storing instructions that, when executed by the one or more computers, cause the one or more computers to perform operations comprising:
• obtaining network activity data on a device within a property over a particular time period,
• obtaining, occupancy data indicating a physical presence of people within the property over the particular time period;
• determining (i) that the network activity data for the device within the property indicates abnormal network traffic for the device and (ii) that the abnormal network traffic occurred over the particular time period for which the occupancy data indicated that the property was unoccupied;
• and
• in response to determining (i) that the network activity data for the device within the property indicates abnormal network traffic for the device and (ii) that the abnormal network traffic occurred over the particular time period for which the occupancy data indicated that the property was unoccupied, providing an indication to a user that network security within the property is likely to be breached.

A non-transitory computer-readable storage device encoded with computer program instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:

• obtaining network activity data on a device within a property over a particular time period,
• obtaining, occupancy data indicating a physical presence of people within the property over the particular time period;
• determining (i) that the network activity data for the device within the property indicates abnormal network traffic for the device and (ii) that the abnormal network traffic occurred over the particular time period for which the occupancy data indicated that the property was unoccupied;
• and
• in response to determining (i) that the network activity data for the device within the property indicates abnormal network traffic for the device and (ii) that the abnormal network traffic occurred over the particular time period for which the occupancy data indicated that the property was unoccupied, providing an indication to a user that network security within the property is likely to be breached.
