Abstract

The present invention is directed to various methods and systems for analysis and processing of video and audio signals from a plurality of sources in real-time or off-line. According to some embodiments of the present invention, analysis and processing applications are dynamically installed in the processing units.

Claims

1. A method comprising:

storing post-alert action rules in a control unit;

delivering video data over Internet Protocol (IP) to two or more processing units having one or more content-analysis applications installed therein, wherein each of the video processing units receives the video data from a respective video sensor;

detecting a first predefined condition based on content-analysis processing of at least a portion of a video data;

sending a notification to the control unit that the predefined condition was detected;

automatically, instructing to install in real-time at least another content-analysis application into at least one of video processing units from an application bank external to the processing units based on at least one of the post-alert action rules;

delivering audio data over Internet Protocol (IP) to the processing units;

detecting a second predefined condition based on content-analysis processing of at least a portion of the audio data; and

providing to a client computer a real-time data stream of video data, wherein the video data is synchronized video data received from at least two sensors.

2. The method of claim 1 further comprising:

recording at least a portion of the video or audio data.

3. The method of claim 2 further comprising:

providing to the client computer recorded data upon receiving a request from the client computer.

4. The method of claim 1 further comprising:

providing to the client computer a real-time stream of audio data upon receiving a request from the client computer.

5. The method of claim 1 further comprising:

providing to the client computer a real-time stream of video data, audio data or a combination thereof according to a predetermined time-based schedule.

6. The method of claim 1 further comprising:

storing results of the content-analysis processing.

7. The method of claim 6, wherein the results comprises number of people counted by a people counting application.

8. The method of claim 6, wherein the results comprises an identifier associated with a voice recognized by a voice recognition application.

9. The method of claim 6, wherein the results comprises an identifier associated with a face recognized by a face recognition application.
