Abstract

A security monitoring system including: an alarm system having detectors for detecting an unauthorized individual in a structure; at least one camera for capturing first image data of the unauthorized individual; a memory for storing second image data of at least one individual authorized to be in the structure; and a data link for transmitting third image data to a remote location upon the detection of the unauthorized individual. The third image data including at least portions of the first and second image data for comparison at the remote location. In a preferred implementation, the first image data includes image data of more than the face of the unauthorized individual and the system further includes a computer vision system for detecting the face of the unauthorized individual from the first image data. In such an implementation, the first and second image data are face images and are arranged in a picture having the unauthorized individual at a top portion of the picture and the authorized individuals arranged along a bottom row of the picture.

Claims

1. A security monitoring system comprising:

an alarm system having means for detecting an unauthorized individual in a structure;

at least one camera for capturing first image data of the unauthorized individual;

a memory for storing second image data of at least one individual authorized to be in the structure; and

transmitting means for transmitting third image data to a remote location upon the detection of the unauthorized individual, the third image data comprising at least portions of the first and second image data for comparison at the remote location.

2. The security monitoring system of claim 1, further comprising means for compressing the third image data prior to transmission to the remote location.

3. The security monitoring system of claim 1, wherein the at least one camera also captures the second image data.

4. The security monitoring system of claim 3, further comprising means for commanding the at least one camera to capture the second image data.

5. The security monitoring system of claim 4, wherein the means for commanding the at least one camera to capture the second image data comprises entering a unique key sequence on a keypad associated with the alarm system.

6. The security monitoring system of claim 1, wherein the first image data comprises image data of more than the face of the unauthorized individual and the system further comprises a computer vision system for detecting the face of the unauthorized individual from the first image data.

7. The security monitoring system of claim 6, wherein the second image data comprises face image data of the authorized individual and the third image data comprises a comparison of face image data of the unauthorized and authorized individuals.

8. The security monitoring system of claim 1, wherein the transmitting means comprises a data link between the structure and the remote location.

9. The security monitoring system of claim 1, wherein the first image data is video image data.

10. The security monitoring system of claim 9, wherein the second image data is still image data.

11. The security monitoring system of claim 10, wherein the third image data is composed in a picture comprising a frame from the video image data arranged in a first portion and the still image data of the at least one individual authorized to be in the structure arranged in a second portion.

12. The security monitoring system of claim 11, wherein the first portion comprises a top portion of the picture and the second portion comprises a row of the still image data for each of the at least one individuals authorized to be in the structure arranged along a bottom portion of the picture.

13. A method for security monitoring of a structure, the method comprising the steps of:

storing second image data of at least one individual authorized to be in the structure;

detecting an unauthorized individual in the structure;

capturing first image data of the unauthorized individual; and

transmitting third image data to a remote location upon the detection of the unauthorized individual, the third image data comprising at least portions of the first and second image data for comparison at the remote location.

14. The method of claim 13, further comprising the step of compressing the third image data prior to the transmitting step.

15. The method of claim 13, further comprising the step of capturing the second image data prior to the storing step.

16. The method of claim 15, further comprising the step of commanding the capturing of the second image data.

17. The method of claim 16, wherein the commanding step comprises entering a unique key sequence on a keypad associated with an alarm system for detecting the unauthorized individual in the structure.

18. The method of claim 13, wherein the first image data comprises image data of more than the face of the unauthorized individual and the method further comprising the step of detecting the face of the unauthorized individual from the first image data.

19. The method of claim 13, further comprising the step of composing the third image data in a picture such that the first image data is a frame from video image data arranged in a first portion and the second image data is still image data of the at least one individual authorized to be in the structure arranged in a second portion.

20. The method of claim 19, wherein the first portion comprises a top portion of the picture and the second portion comprises a row of the still image data for the at least one individual authorized to be in the structure arranged along a bottom portion of the picture.
