Abstract

In some embodiments, methods and systems of detecting and monitoring shoplifting of products by individuals at a retail facility include sensors coupled to a product and located at a fixed threshold distance relative to each other. The sensors are configured to generate an alert signal indicating that the fixed threshold distance between the first and second sensors has been altered. An alert sensor positioned in the product stocking area of the retail facility is configured to receive the alert signal from one or both of the product sensors. A central computing device at the retail facility is configured to determine the alert sensor that received the alert signal, and to activate a video camera in order to acquire a photo or video of the portion of the product stocking area of the retail facility associated with the alert sensor that received the alert signal.

First claim

What is claimed is:

1. A system for detecting and monitoring shoplifting of products by individuals at a retail facility, the system comprising:
a first product sensor attached to a product stocked in a product stocking area of the retail facility;
a second product sensor attached to the product, the first and second product sensors being located at a fixed threshold distance relative to each other, wherein at least one of the first and second product sensors is configured to:
transmit a signal indicating a current distance between the first and second product sensors; and
generate an alert signal indicating that the fixed threshold distance between the first and second product sensors has been altered;

an alert sensor not attached to the product and configured to receive the alert signal from at least one of the first and second product sensors;
a video camera positioned to monitor a portion of the product stocking area of the retail facility associated with the alert sensor;
a processor-based computing device in communication with the first and second product sensors, the alert sensor, and the video camera, the computing device being configured to:
determine the alert sensor that received the alert signal; and
activate the video camera;

wherein the activated video camera is configured to acquire at least one moving or still image of the portion of the product stocking area of the retail facility associated with the alert sensor that received the alert signal.

2. The system of claim 1 , further comprising an electronic database configured to store:
data indicating identifying information associated with the product, the first product sensor, and the second product sensor;
data indicating the fixed threshold distance between the first and second product sensors; and
data indicating a current distance between the first and second product sensors.

3. The system of claim 1 , further comprising an electronic database configured to store identifying information associated with the alert sensor.

4. The system of claim 1 , wherein the computing device is configured to detect, based on the signal indicating the current distance between the first and second product sensors received from the at least one of the first and second product sensors, that the fixed threshold distance between the first and second product sensors has been altered, and to send a control signal to the at least one of the first and second product sensors in order to cause the at least one of the first and second product sensors to generate the alert signal.

5. The system of claim 4 , wherein the computing device generates a time stamp indicating a time when the control signal is sent by the computing device to the at least one of the first and second product sensors.

6. The system of claim 5 , wherein the at least one of the first and second product sensors is configured to transmit the alert signal to the alert sensor and the alert sensor is configured to transmit, to the computing device, a notification signal indicating that the alert signal was received by the alert sensor from the at least one of the first and second product sensors, and wherein the computing device generates a time stamp indicating a time when the notification signal is received by the computing device from the alert sensor.

7. The system of claim 6 , further comprising a plurality of alert sensors positioned such that at least one of the alert sensors is located at each portion of the product stocking area of the retail facility, and wherein the computing device is configured to analyze the data indicating the time stamp when the control signal is sent by the computing device and the data indicating the time stamp when the notification signal is received by the computing device from the alert sensor in order to determine which of the plurality of the alert sensors was the first to receive the alert signal from the at least one of the first and second product sensors.

8. The system of claim 1 , wherein the activated video camera is configured to transmit, to the computing device, the at least one moving or still image of the portion of the product stocking area of the retail facility associated with the alert sensor that received the alert signal.

9. The system of claim 8 , wherein the computing device is configured to transmit the at least one moving or still image of the portion of the product stocking area of the retail facility associated with the alert sensor that received the alert signal to the at least one of the electronic database and an electronic device of a security worker at the retail facility.

10. The system of claim 1 , further comprising at least one scanner proximate an exit from the retail facility, the scanner being configured to:
detect whether a product being removed from the retail facility by an individual includes the first and second product sensors; and
generate an alert when the product being removed from the retail facility by the individual includes at least one of the first and second product sensors.

11. A method for detecting and monitoring shoplifting of products by individuals at a retail facility, the method comprising:
providing a first product sensor attached to a product stocked in a product stocking area of the retail facility;
providing a second product sensor attached to the product, the first and second product sensors being located at a fixed threshold distance relative to each other;
providing an alert sensor not attached to the product and configured to receive a signal from at least one of the first and second product sensors;
providing a video camera positioned to monitor a portion of the product stocking area of the retail facility associated with the alert sensor;
providing a processor-based computing device in communication with the first and second product sensors, the alert sensor, and the video camera;
transmitting, via at least one of the first and second product sensors, a signal indicating a current distance between the first and second product sensors;
generating, via the at least one of the first and second product sensors, an alert signal indicating that the fixed threshold distance between the first and second product sensors has been altered;
receiving the alert signal via the alert sensor;
determining, via the computing device, the alert sensor that received the alert signal;
activating, via the computing device, the video camera; and
acquiring, via the activated video camera, at least one moving or still image of the portion of the product stocking area of the retail facility associated with the alert sensor that received the alert signal.

12. The method of claim 11 , further comprising providing an electronic database configured to store:
data indicating identifying information associated with the product, the first product sensor, and the second product sensor;
data indicating the fixed threshold distance between the first and second product sensors; and
data indicating a current distance between the first and second product sensors.

13. The method of claim 11 , further comprising providing an electronic database configured to store identifying information associated with the alert sensor.

14. The method of claim 11 , wherein the transmitting step further comprises detecting, via the computing device and based on the signal indicating the current distance between the first and second product sensors received from the at least one of the first and second product sensors, that the fixed threshold distance between the at least one of the first and second product sensors has been altered, and sending, from
