Security monitoring methodology using digital audio
First Claim
1. A universal controller comprising:
- two or more inputs that receive signals from two or more audio sensors;
a data compressor that compresses signals received from the audio sensors into compressed data comprising at least compressed audio data, said data compressor in communication with said two or more inputs to receive the signals from the audio sensors;
a buffer in communication with said data compressor to store the compressed data;
a detector in communications with said data compressor to receive the compressed data and determine when a triggering event has occurred; and
a packet transmitter that transmits the compressed data to disparate locations in response to the determination of the triggering event,wherein the transmitted compressed data comprises not only audio data which corresponds in time to the triggering event but also buffered audio data which corresponds in time with a predetermined amount of time preceding the triggering event.

Abstract
A security monitoring methodology and device using digital audio. A security control device integrates physical intrusion detection functions, physical access control functions, and compressed, streaming, digital audio transmission capability. The device provides interfaces for a number of sensor inputs, including standard alarm monitoring sensors and audio sensors. The device is capable of communicating with a monitoring system over a variety of digital networking configurations options, including TCP/IP, via embedded Ethernet interface, or serial modem communications over telephone or digital cellular networks using PPP network protocol. The device may use backup channels of communications including telephone and cellular network communications. All communications with the device, whether to monitoring receiver or other local devices, may be secured with a minimum AES 128-bit encryption.

8. A method of processing signals received from security systems, comprising:
-
receiving two or more audio input signals from two or more audio sensors; summing the two or more audio input signals; digitizing the summed two or more audio input signals; compressing the digitized signals as data; buffering the compressed data; detecting the compressed data to determine when a triggering event occurred; and transmitting the compressed data to disparate locations in response to the determination of the triggering event in substantially real-time, wherein the transmitted compressed data comprises not only audio data which corresponds in time to the triggering event but also buffered audio date which corresponds in time to a predetermined amount of time preceding the triggering event. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A security control system, comprising:
-
remote sensor devices to detect when a triggering event has occurred, wherein at least two of said remote sensor devices simultaneously monitor audio; controller devices for processing input data from the remote sensor devices for storage as multiple data streams, and for routing the data streams over networks, wherein at least two of said input data comprises audio data; memory devices for buffering the input data; and network interfaces providing communications between the controller and one or more networks, wherein each one of the controller devices is connected to a plurality of the sensor devices; and wherein, upon detection of a triggering event, the controller devices transmit not only the audio data streams which correspond in time to the triggering event, but also the buffered audio data streams which correspond in time to a predetermined amount of time preceding the triggering event. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
