Abstract

A system and method is provided for image surveillance of areas of interest for items having radio frequency identification (RFID) tags. These areas of interest are often times unmonitored due to privacy concerns. The present invention discloses an image surveillance system and method, that upon indication of an RFID tag coming within proximity of a portal system having an RFID reader, records one or more images of the area of interest, so as to capture a subject associated with the RFID tagged item moving into or through the area of interest. Such applications for embodiments of the present invention are directed to monitor items of interest in retail stores, restaurants, shipping and receiving locations, and other public areas.

Claims

1. A method comprising:

monitoring a portal adjacent to a predefined area of interest for a presence of a radio frequency identification (RFID) tag by sending an interrogation signal from an RFID reader located the portal, the predefined area of interest being an area that is not monitored by video;

determining whether a user has entered the predefined area of interest through the portal with the RFID tag in response to the RFID reader receiving a response from the RFID tag to the interrogation signal;

recording surveillance videos of at least the portal when the user with the RFID tag is determined to be within the area of interest;

determining that the user has exited the portal based on the surveillance videos but that the RFID tag did not exit through the portal; and

transmitting, to a monitor, an indication of the presence of the RFID tag within the area of interest.

2. The method of claim 1, wherein the transmitting the indication of an RFID tag occurs through audible alarm, visual alarm, or text-based message.

3. The method of claim 1, wherein the transmitting comprises transmitting at least the image to a memory component of a processor.

4. The method of claim 3, further comprising:

modifying the image through one or more enhancement options, the one or more enhancement items comprising at least one of;

providing still images;

focusing on a particular image;

increasing image resolution;

increasing quantity of images recorded per second;

changing the images from black and white to color and vice versa;

changing the images to infrared;

enabling motion of a video surveillance device; and

inserting a time and date stamp into the images.

5. The method of claim 1, further comprising panning a first image surveillance device and tracking the RFID tag based on the radio frequency of the RFID tag within the area of interest until a second image surveillance device records one or more images of at least the area of interest, wherein the second image surveillance device is configured to monitor the area of interest.

6. The method of claim 1, further comprising tracking a position of the RFID tag within the area of interest based on the presence of a radio frequency of the RFID tag.

7. The method of claim 6, wherein tracking the position includes active movement of an image surveillance and a physical location tracking.

8. The method of claim 1, further comprising:

determining a selection of an enhancement option to the image from a user;

modifying the image according to the selection of the enhancement option; and

processing the enhancement option of the image through a processing unit while recording through an image surveillance device.

9. A radio frequency identification (RFID) tag surveillance system comprising:

an RFID reader that is located at a portal that is adjacent to an area of interest and that sends an interrogation signal to an RFID tag that passes through the portal, wherein a user is determined to have entered the predefined area of interest through the portal with the RFID tag in response to the RFID reader receiving a response from the RFID tag to the interrogation signal;

an image surveillance device that records surveillance video of the portal when the user with the RFID tag is determined to be within the area of interest; and

a transmitter that transmits a notification when the user is determined to have exited the portal based on the surveillance videos but that the RFID tag did not also exit through the portal.

10. The surveillance system of claim 9, wherein at least the recording component of the video surveillance system is located proximate to the RFID tag reader.

11. The surveillance system of claim 9, wherein the RFID tag reader is coupled to the processing unit through a wired, wireless, or partially-wired network.

12. The surveillance system of claim 9, further comprising a portal system located adjacent to the area of interest, wherein the portal system comprises the RFID reader.

13. A data and image surveillance system comprising:

a radio frequency identification (RFID) reader that reads an RFID tag entering an area via the portal, wherein a user is determined to have entered an area via a portal system with the RFID tag in response to the RFID reader reading the RFID tag;

an image surveillance device that is in communication with the RFID reader and that records one or more images of an area where the RFID tag is located when the user with the RFID tag is determined to be within the area of interest; and

transmitting the one or more recorded images to a monitoring system when the user is determined to have exited the portal based on the surveillance videos but that the RFID tag did not also exit through the portal.

14. The system of claim 13, wherein the RFID reader is located within the portal system.

15. The system of claim 13, further comprising the portal system in communication with the RFID reader, wherein the portal system communicates across a wired, wireless, or partially-wired network.

16. The system of claim 13, further comprising:

a processor that modifies the one or more images through one or more enhancement options, the one or more enhancement items comprising at least one of;

providing still images;

focusing on a particular image;

increasing image resolution;

increasing quantity of images recorded per second;

changing the images from black and white to color and vice versa;

changing the images to infrared;

enabling motion of the video surveillance device; and

inserting a time and date stamp into the images.

17. The system of claim 13, wherein a selection from a user of an enhancement option to the one or more images is received, wherein the selection includes one or more instructions for processing the one or more images while being recorded.

18. The system of claim 13, wherein the triggering event occurs when an item having the RFID tag is within a proximity of the RFID reader or crosses through a threshold established by a portal system associated with the RFID reader.

19. The system of claim 13, further comprising an alarm that is activated upon the RFID tag being read by the RFID reader.

20. The system of claim 13, further comprising one or more portal systems located proximate to the area, wherein each of the one or more portal systems has a radio frequency identification (RFID) reader.
