Abstract

A process of identifying suspicious object movements in an incident location. An electronic computing device obtains incident information identifying a time of occurrence and a location of an incident. The electronic computing device identifies internet-of-things (IoT) devices deployed in the incident location and accesses received signal strength indication (RSSI) information associated with a selected IoT device. The RSSI information includes historical RSSI values that were captured at the IoT device during the time of occurrence of the incident. The electronic computing device generates a suspicious object movement pattern corresponding to the at least one IoT device based on variations within the historical RSSI values that were captured at the at least one IoT device during the first time period. A display or audio output device provides a corresponding visual or audio output indicating the suspicious object movement pattern corresponding to the IoT device.
