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 multimedia surveillance sensor arrangement comprising an H.323 or SIP adapted first end-point and adapted for establishing a multimedia connection for communicating surveillance media according to a multimedia communication protocol standard corresponding to the H.323 standard recommendation or the SIP standard recommendation, and connected to a first multimedia H.323 or SIP adapted network, said surveillance media representing at least one sensed parameter;

a surveillance receiver comprising an H.323 or SIP adapted second end-point and adapted to receiving all or part of said surveillance media and connected to a second multimedia adapted network; and

a network arrangement comprising said first and second multimedia adapted networks and interconnected by media gateways and at least one network controller;

wherein said network controller is a SIP server or an H.323 Gatekeeper and adapted to serve as an endpoint for receiving said surveillance media communicated from said surveillance sensor, said network controller further adapted to interact with said received surveillance media, said network controller responsive to information contained in said received surveillance media and adapted to communicate an event message or at least part of said received surveillance media to said multimedia surveillance receiver on basis of said information.

2. The arrangement of claim 1, wherein said surveillance sensor includes a camera.

3. The arrangement of claim 1, wherein said surveillance sensor includes a microphone.

4. The arrangement of claim 1, wherein said information comprises one of a video signal and an audio signal.

5. The arrangement of claim 1, wherein said network controller is responsive to a change in said information.

6. The arrangement of claim 5, wherein said change is a change of one of (1) a pixel or a group of pixels of said video signal and (2) a sample or a group of samples in said audio signal.

7. The arrangement of claim 1, wherein said surveillance receiver is one of a multimedia terminal, a mobile terminal, and a mobile telephone.

8. A multimedia network controller, said controller being a SIP server or H.323 Gatekeeper for use in a multimedia surveillance arrangement, said arrangement including a network according to a H.323 standard recommendation or a SIP standard recommendation, at least one first multimedia terminal in communication with said network and having an associated surveillance sensor, and at least one second terminal in communication with said network for receiving an event message generated by the multimedia network controller, wherein said controller is adapted to serve as an endpoint for receiving surveillance media from said at least one first multimedia terminal and to serve as an endpoint for transmitting a surveillance event message to said at least one second terminal and said controller including a surveillance media processing means responsive to, and interacting with, said surveillance media for generating said event message on basis of at least one event information item contained in said surveillance media.

9. The multimedia network controller of claim 8, herein said surveillance media processing means is adapted to forwarding to said at least one second terminal said surveillance media received from said at least one first multimedia terminal.

10. The multimedia network controller of claim 8, wherein said surveillance media processing means is adapted to arranging a multimedia connection between said at least one first multimedia terminal and said at least one second terminal for transporting surveillance media there-between.
