  • Patent number: 11823545
    Abstract: A threat detection and isolation system is provided. The system includes a housing having an upper wall and a plurality of sidewalls extending therefrom defining an interior volume. A door is affixed to the housing on at least one of the plurality of sidewalls, the door providing access to the interior volume. A camera is disposed within the housing. At least one sensor is disposed within the housing, wherein the sensor can detect the presence of a predefined dangerous object within the interior volume. Upon detection of the presence of the predefined dangerous object, the door moves to a closed position and a lock engages the door, thereby preventing the door from moving to an open position. In some embodiments, a notification is sent to emergency services via a wireless communication system upon actuation of the sensor.
