Abstract

A multimedia surveillance arrangement comprising a surveillance sensor adapted to communicate by a standard communication protocol media representing at least one sensed parameter according, a plurality of networks interconnected by media gateways and at least one network controller, and a surveillance receiver adapted to receive all or part of said media. The network controller also serves as endpoint for media from the surveillance sensor, is adapted to interact with said received media, is responsive to information contained in the received media, and is adapted to communicate an event message and/or all or part of said received media on basis of said information. The multimedia network controller ca be a SIP server or H.323 Gatekeeper, adapted to interact with said surveillance media, for generating an event message.

Claims

1. A multimedia surveillance arrangement comprising:

a surveillance sensor adapted to communicate media according to an industry standard communication protocol, said media representing at least one sensed parameter, a plurality of networks interconnected by media gateways and at least one network controller, and

a surveillance receiver adapted to receive all or part of said media, wherein said network controller also serves as an endpoint for media communicated from said surveillance sensor, said network controller is adapted to interact with said received media, said network controller is responsive to information contained in said received media and is adapted to communicate an event message and/or all or part of said received media on basis of said information.

2. The arrangement of claim 1, wherein said surveillance sensor is a camera and/or a microphone.

3. The arrangement of claim 1 or 2, wherein said industry standard communication protocol is H.323 or SIP.

4. The arrangement of any of the previous claims, wherein said network controller is a SIP server or an H.323 Gatekeeper.

5. The arrangement of any of the previous claims, wherein said information comprises a video and/or audio signal.

6. The arrangement of any of the previous claims, wherein said network controller response to a change in said information.

7. The arrangement of claim 6, wherein said change is a change of a pixel or a group of pixels of said video signal and/or a sample and/or a group of samples in said audio signal.

8. The arrangement of any of the previous claims, wherein said surveillance receiver is a multimedia terminal and/or a mobile terminal and/or a mobile telephone.

9. A multimedia network controller, said controller being a SIP server or H.323 Gatekeeper, wherein said controller is adapted to serve as endpoint for receiving media from a multimedia surveillance device and as endpoint for transmitting a surveillance event message to a receiving device, and includes a means responsive to, and interacting with, said surveillance media for generating said event message.

10. The multimedia network controller of claim 9, wherein said means responsive to, and interacting with, said surveillance media is adapted to forward to said receiving device said surveillance media received from said surveillance device, and/or to arrange a multimedia connection between said surveillance device and said receiving device for transporting surveillance media therebetween.
