1. A system for monitoring a display of products, said system comprising:
- a product display monitoring system configured to generate an invisible wall occupying a portion of a generally vertically oriented plane disposed between at least one associated product held in an associated display and an associated individual; and
a motion detection unit configured to;
receive an electromagnetic signal from a sensor concerning the portion of the plane disposed between at least one associated product held in an associated display and an associated individual;
determine whether the portion of the plane is breached based on temporal deviations in the electromagnetic signal; and
,in response to determining a breach, generate a notification of the breach;
wherein the determination includes determining whether an object moves through the portion of the plane from one side of the plane to the other side of the plane.

Abstract
A system which monitors a display of products includes a motion detection unit. The motion detection unit is configured to receive an electromagnetic signal from a sensor concerning a portion of a plane disposed between at least one product held in a display and an individual. Further, the motion detection unit determines whether the portion of the plane is breached based on temporal deviations in the electromagnetic signal and, in response to determining a breach, generates a notification of the breach.

5. A system for monitoring a display of products, said system comprising:
-
a motion detection unit configured to; receive an electromagnetic signal from a sensor concerning a portion of a plane disposed between at least one associated product held in an associated display and an associated individual; determine whether the portion of the plane is breached based on temporal deviations in the electromagnetic signal; and in response to determining a breach, generate a notification of the breach; wherein the motion detection unit includes; a beam generator which generates an electromagnetic beam continuously scanning across the portion of the plane, wherein the electromagnetic signal includes a reflection of the beam; and wherein the portion of the plane is breached when a difference between reflection times of two consecutives scans exceeds a predetermined threshold.

10. A method for monitoring a display of products, said method comprising:
-
providing a sensor and receiving an electromagnetic signal from the sensor concerning a portion of a plane disposed between at least one product held in a display and an individual; determining whether the portion of the plane is breached based on temporal deviations in the electromagnetic signal; and in response to determining a breach, generating a notification of the breach; wherein the portion of the plane is breached when a limb of the individual reaches towards the display; wherein the determining includes determining whether the limb moves through the portion of the plane from one side of the plane to the other side of the plane; and generating an electromagnetic beam continuously scanning across the portion of the plane, wherein the electromagnetic signal includes a reflection of the beam, wherein the portion of the plane is breached when a difference between reflection times of two consecutives scans exceeds a predetermined threshold.

14. A system for monitoring a display of products, said system comprising:
-
a product display monitoring system configured to generate an invisible wall occupying a portion of a generally vertically oriented plane disposed between at least one associated product held in an associated display and an associated individual; and a motion detection unit configured to; receive an electromagnetic signal from a sensor concerning the portion of the plane disposed between at least one associated product held in an associated display and an associated individual; determine whether the portion of the plane is breached based on temporal deviations in the electromagnetic signal; and
,in response to determining a breach, generate a notification of the breach; wherein the location and the size of the portion of the plane are defined by an operator of the motion detection unit before use of the motion detection unit.
