Mediation Device and Method for Remotely Controlling a Camera of a Security System Using Dual-Tone Multi-Frequency (DTMF) Signals

摘要

A mediation device located in the user's home receives dual-tone multi-frequency (DTMF) signals via a Plane Old Telephone Service (POTS) connection and decodes the signals into signals that are used to control one or more cameras of the user's home security system. The mediation device may be a device that serves only this purpose, or it may be part of another device, such as, for example, an answering machine, a fax machine, or a cordless telephone.
