A digital telephone or an analog telephone system with VOIP conversion is
linked into the surveillance system and transmissions therefrom are
treated as an event requiring an emergency response from the system. The
system supports integration of emergency telephone systems into a
multi-media surveillance system to permit comprehensive and multiple
responses to an event triggered by receipt of the emergency phone call
transmission. The telephone transmission is captured and transmitted to a
surveillance system processor. Upon receipt, the system can react with
any of numerous responses. First, the telephone call is transmitted to a
manned station and may be answered in the normal fashion with a live
voice response. The receipt of the call also activates the entire system
in the same manner as a triggering signal from any other sensor or
appliance. In addition, various other responses may be activated, either
manually or in a pre-programmed hierarchy.
