Abstract: A remote monitoring device is provided for monitoring the status of an electronic display unit. The remote monitoring device includes a current detector connected to an input power cord that provides power to said electronic display unit, the current detector outputting a current detection signal based on the current of the input power cord. The remote monitoring device further includes a cellular communication module that communicates via a cellular communication network to an internet-connected server, and a Wi-Fi communication module that communicates with one or more local Wi-Fi access points and obtains access point identification information related to the one or more local Wi-Fi access points.
