Abstract

A method and apparatus are provided for operating a security system. The method includes the steps of providing a network video camera coupled to the security system through a network, detecting a predetermined activity and increasing a video quality parameter of video transmitted between the network camera and the security system in response to the detected activity for a predetermined period of time.

Claims

1. A method of operating a security system comprising:

providing a network video camera coupled to the security system through a network;

detecting a predetermined activity; and

increasing a video quality parameter of video transmitted between the network camera and the security system in response to the detected activity for a predetermined period of time.

2. The method of operating the security system as in claim 1 wherein the increased video quality parameter further comprises frame rate.

3. The method of operating the security system as in claim 1 wherein the increased video quality parameter further comprises a size of a group of frames between I-frames in an MPEG process.

4. The method of operating the security system as in claim 1 wherein the increased video quality parameter further comprises resolution.

5. The method of operating the security system as in claim 1 wherein the increased video quality parameter further comprises bit rate.

6. The method of operating the security system as in claim 1 wherein the predetermined event further comprises motion or activity in a field of view of the camera.

7. The method of operating the security system as in claim 1 wherein the predetermined event further comprises camera sabotage.

8. A security system comprising:

a network video camera coupled to the security system through a network;

means for detecting a predetermined activity; and

means for increasing a video quality parameter of video transmitted between the network camera and the security system in response to the detected activity for a predetermined period of time.

9. The security system as in claim 8 wherein the increased video quality parameter further comprises frame rate.

10. The security system as in claim 8 wherein the increased video quality parameter further comprises a size of a group of frames between I-frames in an MPEG process.

11. The security system as in claim 8 wherein the increased video quality parameter further comprises resolution.

12. The security system as in claim 8 wherein the increased video quality parameter further comprises bit rate.

13. The security system as in claim 8 wherein the predetermined event further comprises motion or activity in a field of view of the camera.

14. The security system as in claim 8 wherein the predetermined event further comprises camera sabotage.

15. A security system comprising:

a network video camera coupled to the security system through a network;

a predetermined activity detected by the security system; and

a video quality processor that increases a video quality parameter of video transmitted between the network camera and the security system in response to the detected activity for a predetermined period of time.

16. The security system as in claim 15 wherein the increased video quality parameter further comprises frame rate.

17. The security system as in claim 15 wherein the increased video quality parameter further comprises a size of a group of frames between I-frames in an MPEG process.

18. The security system as in claim 15 wherein the increased video quality parameter further comprises resolution.

19. The security system as in claim 15 wherein the increased video quality parameter further comprises bit rate.

20. The security system as in claim 15 wherein the predetermined event further comprises motion or activity in a field of view of the camera.

21. The security system as in claim 15 wherein the predetermined event further comprises camera sabotage.
