System and method smart stand-alone multi-sensor gateway for detection of person-borne threats

A method of detecting person-borne threats using a stand-alone multi-sensor gateway system, the method comprising the steps of:

• providing a first pillar and a second pillar spaced apart to define a passageway;
• providing a plurality of first sensors on the first pillar and a plurality of second sensors on the second pillar, the sensors including at least one magnetic sensor and at least one optical break-beam sensor;
• providing an integrated camera on the first or second pillar;
• providing a Wi-Fi® module on the first pillar configured for the pillars to communicate over Wi-Fi®;
• providing a display screen on the first pillar and second pillar for displaying a plurality of screen states wherein:
• the first display screen is configured to face incoming patrons and display a screen state selected from a group consisting of:
• a READY state, a SCAN state, a PASS state, and an ALERT state;
• and
• the second display screen is configured to face security personnel and display alert information including a visual indication of a detected threat;
• an edge computing device housed within one of the pillars, comprising a processor configured to:
• receive sensor and camera data;
• perform threat detection using embedded artificial intelligence models locally, without reliance on a remote server;
• trigger a change in the screen state based on the threat detection result;
• and
• transmit alert data wirelessly to a security system.
