Abstract

An integrated security system integrates broadband and mobile access and control with conventional security systems and premise devices to provide a tri-mode security network having remote connectivity and access. The integrated security system delivers remote premise monitoring and control functionality to conventional monitored premise protection and complements existing premise protection equipment. The integrated security system integrates into the premise network and couples wirelessly with the conventional security panel, enabling broadband access to premise security systems. Automation devices can be added, enabling users to remotely see live video or pictures and control home devices via a personal web portal or other client device. Camera management enables automatic configuration and management of cameras in the premise network. The camera management extends to remote control and monitoring from outside the firewall of the premise network to include routing of images or video from a streaming source device to a requesting client device.
