    摘要: A device, system and method for determining incident objects in secondary video is provided. An electronic device: plays, at a display screen, a primary video from a primary video source located at a primary location; determines an incident type associated with the primary video; determines incident object(s) associated with the incident type; detects a particular incident object in a secondary video from a secondary video source located at a secondary location within a threshold distance of the primary location, the particular incident object appearing in the secondary video within a threshold time period from a current playback time of the primary video; determines a relative direction of a location of the particular incident object from the primary location; and controls the display screen to render a particular visual indicator of the particular incident object over or adjacent the primary video at a position indicative of the relative direction.

    摘要: A device, system and method for interoperability between digital evidence management systems (DEMS) is provided. A DEMS proxy computing device received, from a requesting device, a search string requesting digital evidence. The proxy provides, to a plurality of separate DEMS devices maintained by separate public safety agencies: corresponding search strings; and identification information identifying one or more of: a public safety role of a user of the requesting device, and a public safety agency membership of the user. The proxy receives, from at least a particular DEMS device, of the plurality of separate DEMS devices, a digital evidence record based on the search string, the digital evidence record describing a piece of digital evidence managed by the particular DEMS device, and including chain-of-custody information. The proxy provides, to the requesting device, the digital evidence record and the chain-of-custody information.

    摘要: A device, system and method for positioning monitors in schools is provided. One or more memories store: adversarial relationship data identifying adversarial relationships between students at a school; and schedule data indicative of spatiotemporal locations of the students having the adversarial relationships. A device accesses the adversarial relationship data and the schedule data. The device determines, based on the schedule data, spatiotemporal crosspaths at the school of the students having the adversarial relationships. The device determines a ranking of the spatiotemporal crosspaths. The device assigns one or more monitors to one or more of the spatiotemporal crosspaths. The device transmits notifications to communication devices associated with the one or more monitors, the notifications to instruct the one or more monitors to move to a respective assigned spatiotemporal crosspath.

    摘要: A device, system and method for controlling a passage barrier mechanism is provided. While failing to detect, via a biometric imaging system in communication with a passage barrier mechanism, unauthorized users in a first area of interest of the biometric imaging system, a device: maintains the passage barrier mechanism in a multiple entry state in which multiple users at a time authenticate, via the biometric imaging system, and enter therethrough. Responsive to detecting, via the biometric imaging system, an unauthorized user in the first area of interest, the device: transitions the passage barrier mechanism from the multiple entry state to a single entry state in which only a single user at a time authenticates, via the biometric imaging system, and enters therethrough; and changes a biometric authentication range of the biometric imaging system from the first area of interest to a smaller second area of interest.
