Abstract: A video camera system includes a video capture device and a camera controller. The video capture device includes a sensor that receives light, a shutter that selectively permits the light to be received at the sensor based on a shutter speed, and a frame processor that generates a plurality of video frames based on the light. The camera controller includes a frame parameter calculator that calculates a luminance parameter of the plurality of frames, a frequency domain analyzer that executes a frequency domain analysis based on the luminance parameter to generate a plurality of luminance amplitude values mapped to a plurality of frequencies, and a control signal generator that generates a target shutter speed based on the plurality of luminance amplitude values mapped to the plurality of frequencies, and transmits a control signal based on the target shutter speed to cause the shutter to operate at the target shutter speed.

Abstract: A frictionless access control system and method embodying satellite cameras for facial recognition are disclosed. The cameras capture image data of individuals at an access point such as a door. Preferably, two or more cameras are placed on opposite sides of the access point to increase the likelihood that the individuals are captured in the image data. A facial cropper module extracts facial patches from the image data, and a facial signature module computes facial signatures from the facial patches. A facial recognition module receives the computed facial signatures from the facial signature module, matches the computed facial signatures to stored facial signatures, and sends user identity information of individuals corresponding to the stored facial signatures to the facial signature module when the computed facial signatures match the stored facial signatures.

Abstract: Methods and system for distributed cameras and demographics analysis are disclosed. In one embodiment, the enterprise security system includes a tracking system for tracking individuals within the enterprise, surveillance cameras that capture image data including the individuals within the enterprise, a physical classifier module for determining physical characteristics of the individuals in the image data, and a security integration system for determining whether the tracked individuals match the physical characteristics.

Abstract: Methods and system for monitoring and assessing employee moods are disclosed. A proposed enterprise employee monitoring system includes surveillance cameras, a facial recognition module, an emotional analyzer module, and an employee database. The surveillance cameras capture image data including employee individuals within the enterprise. The facial recognition module identifies the individuals in the image data, and the emotional analyzer module determines an emotional state of the individuals based upon the image data. The employee database stores employee information and the emotional state information from the emotional analyzer module, based upon the identification performed by the facial recognition module.

Abstract: Methods and system for employee monitoring and business rule and quorum compliance monitoring are disclosed. A proposed system includes one or more tracking systems for tracking movement of individuals in an enterprise, databases of business rules and operations schedules, and a business rules validation system for determining whether compliance with the business rules based on the operations schedule and the movement of the individuals in the enterprise has been achieved.

Abstract: A frictionless access control system and method providing ultrasonic user location are disclosed. The access control system authorizes users within proximity of an access point such as a door, based upon user information (e.g. credentials) sent in RF wireless messages from user devices carried by the users. When the users are authorized, the system instructs the user devices to transmit coded acoustic signals. An positioning unit at the access point includes an ultrasonic microphone array, which is located above the access point and detects the acoustic signals. The positioning unit determines an angle of arrival (AoA) of the acoustic signals at microphones of the array, and determines positions of the users relative to the access point from the AoA. In one implementation, pre-authorized users are granted access when the determined positions of the users are within an inner zone of the access point.

Abstract: Methods and systems for controlling access to enterprise resources based on tracking are disclosed. In one implementation, an enterprise security system includes one or more tracking systems, an information technology (IT) system, and a security integration system (SIS). The one or more tracking systems track movement of individuals throughout the enterprise. The SIS blocks access to the computer resources based on the tracked movement of the individuals within the enterprise.
