Abstract: An alarm system includes an alarm panel that signals sensed alarm conditions at a premises to a monitoring server over a packet switched data network. The alarm panel also senses and buffers audio at the premises. In response to a sensed alarm condition, buffered audio, buffered prior to signalling the sensed alarm condition, is transferred to the monitoring station. The alarm panel may further receive live audio from the premises. Data representing live audio and buffered audio may be transferred concurrently, allowing an operator at a monitoring center to listen to audio arising from events before and after an alarm is signalled. The alarm system may further allow real-time communication between the monitoring center and panel.

Abstract: An alarm monitoring station is capable of establishing a two way communications channel over a network to connect the monitoring station and alarm panels at monitored premises, for real time voice communication between the panels and the monitoring station. The monitoring station is further operable to provide pre-programmed voice messages to the alarm panels based on the sensed alarm condition over the two way communications channel. In this way, occupants at the premises may be notified of the sensed condition before speaking with an operator at the monitoring station.
