Abstract

Alarm customers on VoIP may use an adapter for conversion to Internet Protocol (IP) signals or may have an alarm system that uses IP signals to transmit alarm signals over the Internet. IP signals from alarm customers may go to any monitoring center for alarm system monitoring. IP signals from alarm systems using IP conversion equipment can go only to monitoring centers with specialized receiving equipment specific to the type of transmitting equipment in use at the customer'"'"'s premises. There is a pool of customers, whose dealers would convert to IP and stay with the current monitoring center if the center invested in receiving equipment. For the many small centers who will not or cannot invest in receiving equipment, the present invention will take IP signals from any or all brands of IP transmitting equipment, to a central server then retransmit to any center over POTS to the alarm monitoring center. Thus, an alarm monitoring center need not invest in a number of different IP monitoring systems in order to be IP monitoring compliant.

Claims

1. A method comprising the steps of:

receiving, at a middleware server, a plurality of customer alarm signals having different formats, each of the customer alarms signals received from a different alarm panel associated with a different alarm system at a different premises,

converting, at the middleware server, the plurality of customer alarm signals into monitoring center alarm signals having a common format, and

transmitting from the middleware server to an alarm monitoring center, the monitoring center alarm signals having the common format, for display at the alarm monitoring center as respective alarm signal messages,

wherein the plurality of customer alarm signals having different formats comprise a customer alarm signal in a POTS (Plain Old Telephone Service) format, and

wherein the converting step comprises converting the customer alarm signal in the POTS format into an IP signal using a VoIP (Voice over Internet Protocol) converter.

2. The method of claim 1, wherein the customer alarm signals having different formats comprise a customer alarm signal in an IP signal format.

3. The method of claim 1, wherein the step of converting further comprises the steps of:

looking up a customer number derived from one of the customer alarm signals, in a database,

determining customer alarm system type and an associated alarm monitoring center for the looked up customer number, and

converting the one customer alarm signal to one of the monitoring center signals having the common format, based on the determined alarm system type and the determined associated alarm monitoring center.

4. The method of claim 1, wherein one of the customer alarm signals comprises an Internet Protocol (IP) alarm signal, and the monitoring center alarm signals comprise Public Switched Telephone Network (PSTN) alarm signals.

5. The method of claim 1, further comprising the steps of:

at the middleware server, looking up a customer number derived from one of the customer alarm signals in a database,

at the middleware server, determining whether a customer associated with the customer number has elected to be directly notified of a customer alarm signal, and

transmitting, from the middleware server to the customer, a signal indicating that the one of the customer alarm signals has been generated.

12. The method of claim 1, wherein the different formats and the common format collectively comprise IP, POTS, and PSTN formats.

13. The method of claim 1, wherein the middleware server comprises a server farm.

14. The method of claim 1, wherein the different alarm panels comprise IP-enabled alarm panels.

15. The method of claim 1, wherein the different formats comprise different IP formats.

16. The method of claim 1, wherein the different premises have different associated customers.

6. A system comprising:

a plurality of customer alarm systems, each operative to generate a respective customer alarm signal in a different format,

a plurality of communication links, operative to transmit the respective customer alarm signals to a middleware server,

the middleware server, operative to receive the transmitted respective customer alarm signals,

a converter in the middleware server, operative to convert the received respective customer alarm signals to monitoring center alarm signals having a common format,

another communication link, operative to transmit from the middleware server to an alarm monitoring center, the monitoring center alarm signals,

the alarm monitoring center, operative to receive the monitoring center alarm signals, and

one or more displays at the alarm monitoring center, operative to display the monitoring center alarm signals as alarm signal messages,

wherein the system comprises;

a legacy alarm panel operative to generate a customer alarm signal in a POTS (Plain Old Telephone Service) format to produce a POTS customer signal, and

a VoIP (Voice over Internet Protocol) converter, operative to convert the POTS customer signal to an IP (Internet Protocol) format and output one of the respective customer alarm signals that comprises an IP signal.

7. The system of claim 6, wherein one of the customer alarm systems comprises the legacy alarm panel.

8. The system of claim 6, wherein one of the customer alarm systems comprises an IP signal generating alarm panel operative to generate one of the respective customer alarm signals in an IP signal format.

9. The system of claim 6, wherein the middleware server comprises:

a database operative to look up a customer number derived from one of the respective customer alarm signals, in a database, and

a processor programmed to determine customer alarm system type and monitoring center for the customer number, and to implement a protocol conversion based on the determined customer alarm system type and the determined monitoring center.

10. The system of claim 6, wherein the converter is operative to convert between Internet Protocol (IP) and Public Switched Telephone Network (PSTN) formats.

11. The system of claim 6, wherein the middleware server comprises:

a database for looking up customer numbers derived from the respective customer alarm signals, and

a processor programmed to determine whether a customer has elected to be directly notified of a customer alarm signal event, and to transmit alarm notifications for customer receipt.

17. The system of claim 6, wherein each customer alarm system in the plurality of customer alarm systems is associated with a different customer.
