The present invention is directed to a system and method for accessing home monitoring devices remotely via a distributed wide-area network (WAN). More specifically, the present invention is directed towards smoke detector system, which monitors for the presence of smoke and communicates the smoke condition to a remote location. The smoke detection system comprises a smoke detection device connected to a communication device. The smoke detection device outputs a signal or a change in a signal upon detection of smoke. This signal or change in signal is monitored by the communication device. The smoke condition is then communicated to the remote central location via a message system.
