Security system with distributed audio and video sources

A method of monitoring for an alarm condition with an alarm system of an installation area that includes:

• a hub station that includes a hub station controller within in a hub station housing,
• a plurality of client stations that are distributed in a plurality of architectural zones of the installation area, the plurality of client stations each including a client station housing and located therein a client station power transformer, a client station speaker, a client station microphone for capturing sounds including audio, a client station video display, a client station image sensor for capturing images including video, and one of a plurality of client station controllers;
• the method comprising:
• monitoring the plurality of client stations over a short range telecommunications network, wherein the short range telecommunications network is a local area network or a personal area network;
• determining, from the monitoring, that an alert condition exists in a corresponding architectural zone of the architectural zones based on the capturing sounds in the corresponding architectural zone;
• and thereupon:
• establishing a first bidirectional communication over the short range telecommunications network with two or more of the plurality of client stations distributed in the plurality of architectural zones;
• establishing a second directional communication with a central station, over a long range telecommunications network that includes one or more Public Switched Telephone Networks (PTSN);
• and
• establishing another bidirectional communication, over a public communications network, with a mobile device,
• wherein each of the bidirectional communications include:
• transmitting voice and image data, representing audio captured from the corresponding microphones of the two or more of the plurality of client stations and video captured from the corresponding image sensors of the two or more of the plurality of client stations, to the central station and the mobile device;
• and
• receiving voice and image data, representing audio and video transmitted by the central station and the mobile device, for outputting via the corresponding client station speakers and the client video displays.
