ABSTRACT:
A method and system for providing redundancy for security systems served by the public switched telephone network (PSTN) includes a cable modem interconnected to a security system controller. Upon detection of inoperability of a telecommunications line serving the system via the PSTN, the cable modem extends an alert message to a security monitoring service via a packet data network. Advantageously, the cable modem can also send video images and audio from the secured premises to the security monitoring system due to the bandwidth capabilities of the packet data network.
