Abstract

A system and method for monitoring sensors via surveillance cameras is disclosed. In the system, surveillance cameras generating image data of scenes, where the sensors are included in the scenes. The sensors detect information concerning the scenes and encode the information so that it can be derived from the image data. Preferably, the sensors encode the information concerning the scenes by modulating a visible light source, the signals of which are captured within the image data by the cameras. An analytics system then analyzes the image data and decodes the information from the sensors encoded within the image data. Preferably, an integrated analytics system of the cameras executes the analysis. Exemplary sensors include sensors for detecting temperature, moisture, audio/voice, and product selection in a retail premises.

First claim

What is claimed is:

1. A system for monitoring sensors, the system comprising:
surveillance cameras generating image data of scenes;
sensors in the scenes that detect information concerning the scenes and encode the information wherein the information can be derived from the image data, the sensors including modulated light sources that are modulated to encode the information;
an analytics system analyzing the image data and decoding light from the modulated light sources to obtain the information from the sensors; and
an image data storage system for storing the image data, wherein the analytics system generates meta data from the decoded information and stores the meta data in connection with the image data to the image data storage system and
wherein the sensors are configured to allow sensor-generated information to be included in the image data without the sensors being connected to network components by data networking hardware.

2. A system as claimed in claim 1 , wherein the sensors detect environmental information and encode the environmental information.

3. A system as claimed in claim 1 , wherein the sensors detect security information and encode the security information.

4. A system as claimed in claim 1 , wherein the sensors detect business information and encode the business information.

5. A system as claimed in claim 1 , wherein the modulated light source generates modulated light in the infrared spectrum.

6. A system as claimed in claim 1 , wherein the modulated light source is modulated at less than a frame rate of the surveillance cameras.

7. A system as claimed in claim 1 , wherein the modulated light source is modulated at less than half a frame rate of the surveillance cameras.

8. A system as claimed in claim 1 , further comprising a security control system that receives the decoded sensor information and generates security alarms.

9. A system as claimed in claim 1 , further comprising a business logic system that receives the decoded sensor information and updates product availability information.

10. A system as claimed in claim 1 , further comprising an environmental control system that receives the decoded sensor information and controls environmental systems.

11. A monitoring method, comprising:
generating image data of scenes;
detecting information concerning the scenes with sensors and encoding the information by modulating light sources of the sensors to encode the information wherein the information can be derived from the image data;
analyzing the image data and decoding the information;
storing the image data in an image data storage system along with meta data from the decoded information; and
storing the meta data in connection with the image data to the image data storage system; and
wherein the sensors are configured to allow sensor-generated information to be included in the image data without the sensors being connected to network components by data networking hardware.

12. A method as claimed in claim 11 , wherein detecting information comprises detecting environmental information and encoding the environmental information.

13. A method as claimed in claim 11 , wherein detecting information comprises detecting security information and encoding the security information.

14. A method as claimed in claim 11 , wherein detecting information comprises business information and encoding the business information.

15. A method as claimed in claim 11 , further comprising generating meta data from the decoded information and storing the meta data with the image data.

16. A method as claimed in claim 9 , wherein the light source generates modulated light in the infrared spectrum.

17. A method as claimed in claim 9 , wherein the light source is modulated at less than a frame rate of surveillance cameras that generated the image data.

18. A system for monitoring sensors, the system comprising:
surveillance cameras generating image data of scenes;
sensors in the scenes that detect business information concerning the scenes and encode the business information wherein the business information can be derived from the image data, wherein each of the sensors comprises a modulated light source that is modulated to encode the business information at less than half a frame rate of the surveillance cameras;
an analytics system analyzing the image data and decoding the business information from the sensors;
an image data storage system for storing the image data, wherein the analytics system generates meta data from the decoded business information and stores the meta data with the image data to the image data storage system; and
a business logic system that receives the decoded business information and updates product availability information; and
wherein the sensors are configured to allow sensor-generated information to be included in the image data without the sensors being connected to network components by data networking hardware.

19. A system as claimed in claim 1 , wherein the modulated light source is modulated to encode the business information and a business logic system receives the decoded business information and updates product availability information.

20. A method as claimed in claim 11 , wherein the modulated light source is modulated at less than half a frame rate of the surveillance cameras.
