Abstract

Improved multi-residence security systems combine distributed cameras with centralized image content processing and interactive monitoring. This particular combination improves cost-effectiveness by increasing the number of residences or other sites that a single operator can monitor, and by providing the operator with the ability to remotely communicate with an intruder.

Claims

1. A multi-residence security system comprising:

a plurality of cameras distributed among remote sites and producing pictorial images;

a central monitoring facility having an image content processor and a monitor, the image content processor analyzing content of the images to prioritize transmission of at least some of the images to the monitor for observation by at least one human operator, wherein the analyzing involves at least some filtering of video images based on image content; and

a plurality of remote speakers producing auditory information at the remote sites under at least partial control of the at least one operator.

2. The security system of claim 1 wherein the plurality of cameras averages at least 75 for each of the at least one operators.

3. The security system of claim 1 wherein the plurality of cameras averages at least 125 for each of the at least one operators.

4. The security system of claim 1 wherein the plurality of cameras averages at least 150 for each of the at least one operators.

5. The security system of claim 1 further having a cost structure that achieves profitability with an average charge of $100 to each of the remote sites per month, in Jan. 1, 1998 dollars.

6. The security system of claim 1 further having a cost structure that achieves profitability with an average charge of $75 to each of the remote sites per month, in Jan. 1, 1998 dollars.

7. The security system of claim 1 further having a cost structure that achieves profitability with an average charge of $50 to each of the remote sites per month, in Jan. 1, 1998 dollars.

8. The security system of claim 1 wherein the at least one operator dynamically affects the prioritizing.

9. The security system of claim 1 wherein at least one of the remote sites has a resident, and the resident employs a wireless remote to dynamically affects the prioritizing.

10. The security system of claim 1 wherein the at least one operator speaks through at least one of the remote speakers.

11. The security system of claim 1 wherein at least one of the pictorial images reaches the image content processor via a dial-up telephone line.

12. The security system of claim 1 wherein at least one of the pictorial images reaches the image content processor via a dedicated telephone line.

13. The security system of claim 1 wherein the plurality of cameras averages at least 75 for each of the at least one operators over a one week period, and further having a cost structure that achieves profitability with an average charge of $100 to each of the remote sites per month, in Jan. 1, 1998 dollars.

14. The security system of claim 1 wherein the at least one operator dynamically affects the prioritizing, and operator speaks through at least one of the remote speakers.

15. The security system of claim 1 wherein the plurality of cameras averages at least 75 for each of the at least one operators over a one week period, and wherein at least one of the pictorial images reaches the image content processor via at least one of a dial-up telephone line and a dedicated telephone line.
