Abstract
The system and method of the present disclosure relates to technology for monitoring a broadcast device that is non-network connected. A wireless device monitors for a broadcast message transmitted wirelessly by the broadcast device. Upon discovery of the broadcast message, the wireless device transmits information from the broadcast message to a remotely located sever via a network. The server stores the broadcast information and determines the status (e.g., online or offline) of the broadcast device. The status is determined based on the detection time (e.g., the last seen time of the broadcast device by the wireless device) and an offline threshold value (e.g., a predetermined time period) that is compared to the current time or time upon which the server received the broadcast information. As a result of the comparison, the server determines whether the broadcast device is online or offline.
