Abstract

Data processing apparatus comprising a video data receiver configured to receive video data, and an audio data receiver configured to receive audio data. The apparatus further comprises an alarm engine configured to analyse said received video and audio data and generate an alarm signal based on an output signal generated by said analysis.

Claims

1. Data processing apparatus for generating an alarm based on the output of at least one camera, comprising:

a video data receiver configured to receive video data; and

an alarm engine configured to perform sequential analysis of said received video data to determine a sequence of at least one incident and to generate an alarm signal the video data corresponds to at least one configuration file in the alarm engine;

the data processing apparatus including a graphical user interface (GUI) for generating the at least one configuration file, which is operable;

(i) to accept user input to generate a plurality of incident analysis functions representing incidents that may be present in the video data, and to display the incident analysis functions so generated;

(ii) to accept user input to generate a plurality of contemporaneous analysis functions that define operations that are performed on at least one incident analysis output signal based on Boolean logic, and to display the contemporaneous analysis functions so generated; and

(iii) to accept user input to generate a plurality of sequential analysis functions that define operations that are performed on at least one of the contemporaneous analysis functions occurring sequentially based on Boolean logic, and to display the sequential analysis functions so generated.

2. The data processing apparatus of claim 1, wherein at least one of the plurality of sequential analysis functions comprises a sequential analysis rule defining a Boolean logical operation and a timeout period that defines a period of time after the sequential analysis rule has been satisfied for which the output of the sequential analysis function remains true.

3. The data processing apparatus of claim 1, wherein the contemporaneous analysis functions comprise a contemporaneous analysis rule defining a Boolean logical operation and a timer period which defines a period of time for which the rule must be satisfied for the contemporaneous analysis output signal to be generated.

4. The data processing apparatus of claim 1, wherein the incident analysis functions comprise a representation of a result of one or more pattern recognition operations performed on the received video data.

5. The data processing apparatus of claim 1, wherein the incident analysis functions performed on the video data are performed on a detection area that comprises a sub-area of said video data.

6. The data processing apparatus of claim 5, wherein the detection area comprises a plurality of sub-areas.

7. The data processing apparatus of claim 1, wherein the video data is data representative of output signals generated by a plurality of cameras.

8. The data processing apparatus of claim 1, further comprising an audio data receiver configured to receive audio data, and wherein the alarm engine is also configured to perform sequential analysis on said received audio data.

9. The data processing apparatus of claim 1, further comprising an external data receiver configured to receive external data, and wherein the alarm engine is also configured to perform sequential analysis on said received external data.

10. A method of operating a data processing apparatus to generate an alarm based on the output of at least one camera, which comprises:

receiving video data from the at least one camera; and

performing sequential analysis on said received video data by an alarm engine to generate an alarm if the video data corresponds to at least one configuration file in the alarm engine;

the at least one configuration file having been generated by means of a graphical user interface (GUI) which is operable;

(i) to accept user input to generate a plurality of incident analysis functions representing incidents that may be present in the video data, and to display the incident analysis functions so generated;

(iii) to accept user input to generate a plurality of sequential analysis functions that define operations that are performed on at least one of the contemporaneous analysis functions occurring sequentially based on Boolean logic, and to display the sequential analysis functions so generated.

11. The method of claim 10, wherein performing sequential analysis comprises sequentially applying a plurality of sequential analysis functions to the received video data, wherein applying at least one of the plurality of sequential analysis functions comprises applying a sequential analysis rule defining a Boolean logical operation and a timeout period that defines a period of time after the sequential analysis rule has been satisfied for which the output of the sequential analysis function remains true.

12. The method of claim 10, wherein performing sequential analysis on said received video data comprises:

performing contemporaneous analysis functions on said received video data; and

generating a contemporaneous analysis output signal, wherein said contemporaneous analysis output signal comprises a representation of the result of one or more contemporaneous analysis functions applied either directly or indirectly to the received video data.

13. The method of claim 12, wherein performing contemporaneous analysis functions comprises applying to the received video data a contemporaneous analysis rule defining a Boolean logical operation and a timer period which defines a period of time for which the rule must be satisfied for the contemporaneous analysis output signal to be generated.
