Systems and methods for detecting potential theft and identifying individuals having a history of committing theft use an electromagnetic emission associated with a personal electronic device associated with an individual is received from at least one of a sensor that is coupled to at least one of a traffic camera or an aerial drone camera. One or more signal properties of the electromagnetic emission are analyzed to determine an emission signature. Video data and video analytics are correlated with the emission signature to identify the individual having possession of the item. The emission signature and video data are stored for later use during a checkout procedure. If an emission signature detected at a checkout station matches that of the individual having possession of the item, and the item is not processed through the checkout station, an alert is issued and the individual is flagged as a potential shoplifter.

It is provided a method for detecting people, the method being performed by a people detector provided by a doorway. The method comprises the steps of: receiving an open signal indicating that a door of the doorway is open; setting a people sensor of the people detector in an active mode based on receiving the open signal; detecting when a person passes through the doorway, using the people sensor; receiving a closed signal indicating that the door of the doorway is closed; transmitting a result of the step of detecting, wherein the step of transmitting is performed based on receiving the closed signal; and setting the people sensor in a power save mode based on receiving the closed signal.

Methods, systems, and apparatuses for managing a wireless network are described herein. A wireless network may include a gateway device, an access point, and a group of client devices. An analytics engine may determine a signal characteristic data for a client device, which may indicate network telemetry data for each of the client devices or associated locations during a time period. The analytics engine may utilize a trained classifier to determine that a signal characteristic indicated by the signal characteristic data for a client device satisfies a threshold.

Systems and methods for detecting or following a person within an observed area. One example system includes a sensor and a processor configured to: receive, from the sensor, a series of readings indicative of the person in the observed area, wherein the observed area is divided into a plurality of zones; determine a sequential occurrence of each of a plurality of ordered events by applying a detection threshold value to the series of readings, wherein the detection threshold value is lower than a noise threshold of the sensor, and wherein each of the plurality of ordered events is associated with at least one of the plurality of zones; and determine a trigger condition based on the sequential occurrence of each of the plurality of ordered events; and provide an instruction to a fixture based on the trigger condition.

Use of multiple sensors to determine whether motion of an object is occurring in an area is described. In one aspect, an infrared (IR) sensor can be supplemented with a radar sensor to determine whether the determined motion of an object is not a false positive.

A anti-theft device with a remote alarm feature is provided. The device is configured to attach to an item of retail merchandise and detect when a predetermined motion and light condition are met which together are indicative of a potential retail theft. Upon detection, the device is configured to generate a local alarm, and send a radio frequency to a remote device to generate an alarm at the remote device.

A system for serving legal documents for initiating legal proceedings which includes a repository, the form of a database which is stored on a server (not shown), for receiving and storing legal documents for initiating legal proceedings, a notification means, in the form of a notifier, for notifying a recipient via an agreed digital address (not shown) of receipt by the database of a legal document, and a payment means (not shown) for allowing the recipient to access the legal document free of charge.
