Abstract: A student tracking system deploys distributed sensors throughout a school building. The distributed sensors receive identification information broadcast by user devices carried by occupants of the school such as students, teachers and school administrators. The student tracking system tracks the location of the occupants within the building based on which sensors most recently detected the user devices. The system sends the location information for the occupants to tracking devices operated by tracking users such as school administrators, emergency responders and/or parents. The tracking devices also present to the parents image data captured by surveillance cameras depicting the students. Additionally, the distributed sensors detect the presence of unauthorized individuals within the school building by determining whether an individual detected via a proximity or motion detector corresponds to identification information for a registered user device received by the sensors.

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: A system and method for space management monitoring and reporting using video analytics are disclosed. Such a building occupancy monitoring system monitors building resources that include rooms, areas such as work areas, and chairs and desks in the rooms, in examples. These building resources are monitored to determine whether the resources are being used by individuals, and for how long. In more detail, the system includes an image analytics module that tracks individuals in image data from surveillance cameras, relative to the building resources. The system also includes an occupancy report module that generates occupancy information including building resources that are used/unused by the individuals. The occupancy information is then used to program building control systems. Dwell maps and motion maps generated by the system, based on the occupancy information, can also be used to guide individuals to available building resources in a ‘hot desking’ environment.

Abstract: Aspects of the present disclosure provide systems and methods for access control using multi-factor validation. In an example, an access control system is designed to be used in conjunction with a first recognition system, such as facial recognition system, a gait recognition system, or audio recognition system, that uses a confidence level to determine whether individuals are authorized to access a restricted area. When the first recognition system is unable to confidently identify the individual, a second recognition system, such as a mobile device system or access card system, may be used to provide second factor verification. Further, stored recognition data may be updated to include information gathered by the first recognition system in response to use of the second factor verification.

Abstract: A computer implemented method for controlling the environmental conditions of a building in accordance with feedback from the occupants of the building is provided. The method includes detecting, by one or more processors, an occupant within a building space, and transmitting, by the one or more processors, a notification message to an occupant device associated with the occupant. The notification message includes a request to provide occupant feedback. The method includes receiving, by the one or more processors, an occupant feedback message from the occupant device. The occupant feedback message includes one or more quality ratings associated with one or more building conditions. The method includes assigning, by the one or more processors, a weighting factor to the occupant feedback message and performing an action to modify at least one of the building conditions responsive to the weighted occupant feedback message.
