Floorplan analysis for monitoring wireless-enabled devices on a property

A system for monitoring a property having multiple rooms, the system comprising:

• a communication interface;
• and
• a processor, configured to:
• ascertain respective locations and types of the rooms by analyzing a floorplan of the property,
• receive via the communication interface, from a Wi-Fi management system of the property, data relating to communication exchanged between one or more wireless-enabled devices on the property and one or more Wi-Fi access points on the property,
• based on the data, identify one or more characteristics and an estimated location of one of the devices,
• based on the estimated location of the device and the locations of the rooms, identify the room in which the device is likely located, and
• based on the characteristics of the device and the type of the identified room, output an alert indicating that the device may be unwanted at least at the estimated location.

A computer software product for monitoring a property having multiple rooms, the product comprising a tangible non-transitory computer-readable medium in which program instructions are stored, which instructions, when read by a processor, cause the processor to:

• ascertain respective locations and types of the rooms by analyzing a floorplan of the property,
• receive, from a Wi-Fi management system of the property, data relating to communication exchanged between one or more wireless-enabled devices on the property and one or more Wi-Fi access points on the property,
• based on the data, identify one or more characteristics and an estimated location of one of the devices,
• based on the estimated location of the device and the locations of the rooms, identify the room in which the device is likely located, and
• based on the characteristics of the device and the type of the identified room, output an alert indicating that the device may be unwanted at least at the estimated location.

A method for monitoring a property, the method comprising:

• receiving by a processor, from a Wi-Fi management system of the property, a preliminary estimated location of a wireless-enabled device on the property and respective signal strengths with which communication from the device was received by one or more Wi-Fi access points on the property;
• identifying by the processor, from a floorplan of the property, respective materials of any signal-attenuating structures between the preliminary estimated location and the access points;
• computing respective estimated distances between the device and the access points, based on the signal strengths and the materials of the signal-attenuating structures;
• computing an estimated location of the device based on the estimated distances;
• and
• outputting an output based on the estimated location.
