Abstract

A security system includes at least one audio sensor located at a premises that receives audio signals and converts the audio signals to digitized audio signals. A server is located remote from the plurality of premises and receives the digitized audio signals from each of the premises. A plurality of clients are in communication with the server, which is operative for selecting the client for receiving digitized audio signals for a selected premises. The client is operative for converting the digitized audio signals from the selected premises into audio for an operator that is monitoring the premises.

Claims

1. A security system for monitoring security at a plurality of premises comprising:

at least one audio sensor located at each of the premises that receives audio signals at the respective premises and converts the audio signals to digitized audio signals, wherein each audio sensor includes a processor and memory having a database of audio signatures that process noises of different frequency components to discern real alarms from false alarms corresponding to intrusion noises at a premises and determine if an alarm exists, and a transceiver connected to said processor that is operative for transmitting and receiving voice commands and at least one of passwords and maintenance testing data;

a server located remote from the plurality of premises that receives the digitized audio signals from each of the premises; and

a plurality of clients in communication with said server, wherein said server is operative for selecting a client for receiving digitized audio signals for a selected premises, and said client is operative for converting said digitized audio signals from the selected premises into audio for an operator that is monitoring the premises, wherein said server is operative for selecting a specific audio sensor for two-way communication for transmitting and receiving voice and at least one of passwords and maintenance data between a selected client and selected audio sensor.

2. A security system according to claim 1, wherein said server is operative for load balancing to select a client for receiving digitized audio signals.

3. A security system according to claim 1, wherein said at least one audio sensor at each premises includes a processor that is operative for determining whether any digitized audio signals are indicative of an alarm condition and should be received at the server.

4. A security system according to claim 3, wherein said at least one audio sensor at each premises includes a memory for storing digital signatures of different audio sounds indicative of an alarm condition, wherein said processor is operative for comparing a digitized audio signal with digital signatures stored within said memory.

5. A security system according to claim 3, wherein said processor at said at least one audio sensor is operative for receiving data relating to audio patterns indicative of false alarms, allowing said processor to recognize audio sounds indicative of false alarms.

6. A security system according to claim 1, and further comprising a premises controller located at each premises for receiving the digitized audio signals and transmitting said digitized audio signals to said server.

7. A security system according to claim 1, wherein said at least one audio sensor at each premises includes a transceiver for receiving a communications signal from said server and transmitting a communications signal to said server.

8. A security system according to claim 1, wherein said digitized audio signal comprises a signal representing a voice.

9. A security system according to claim 1, and further comprising a communications network interconnecting said clients and server.

10. A security system according to claim 9, wherein said communications network comprises an internet.

11. A security system according to claim 9, wherein said communications network comprises a local area network.

12. A security system according to claim 1, and further comprising a first receiver located at said server for receiving digitized audio signals generated by said audio sensors and a second receiver for receiving analog audio signals.

13. A security system for monitoring security at a plurality of premises comprising:

a plurality of audio sensors located at each of the premises that receives audio signals at the respective premises and converts the audio signals to digitized audio signals, wherein each audio sensor includes a processor and memory having a database of audio signatures that process noises of different frequency components to discern real alarms from false alarms corresponding to intrusion noises at a premises and determine if an alarm exists, and a transceiver connected to said processor that is operative for transmitting and receiving voice commands and at least one of passwords and maintenance testing data;

a data bus located at each of the respective premises and interconnecting each of the audio sensors located at a respective premises and receiving the digitized audio signals thereon, wherein each audio sensor includes an identifying data address on its respective data bus;

a premises controller located at each of the premises and interconnected to said respective data bus for receiving said digitized audio signals from each of the audio sensors;

a server located remote from each of the premises and interconnected to each respective premises controller for receiving the digitized audio signals; and

a plurality of clients in communication with said server, wherein said server is operative for selecting a client for receiving digitized audio signals for a selected premises for further processing, wherein said server is operative for selecting a specific audio sensor for two-way communication for transmitting and receiving voice and at least one of passwords and maintenance data between a selected client and selected audio sensor.

14. A security system according to claim 13, wherein said server is operative for load balancing to select a client for receiving digitized audio signals.

15. A security system according to claim 13, wherein each premises controller is operative for selectively addressing each audio sensor on said data bus at said respective premises for transmitting or receiving data to or from a selected audio sensor.

16. A security system according to claim 13, wherein each audio sensor includes a processor that is operative for determining whether any digitized audio signals are indicative of an alarm condition and should be received at the server.

17. A security system according to claim 13, and further comprising a communications network interconnecting each client and server.
