State-of-the-art “Metal Material Classification Detection” intelligent technologies to distinguish threats items from daily necessities like phones, keys, and belt buckles,
Suitability for flexible working modes to adapt versatile applications:
- Weapon Mode: Detect mass casualty weapons by Filtering daily items such as cell phone/belt buckle/keys;
- Electricity Mode: Detect Electric devices such as cell phone/smart watch;
- High Precision Mode: Detect small-size metal (the diameter or length is more than 1cm) by filtering out belt buckle;
- GA Mode: Detecting all metals, comply with Aviation security level
Preset Detection Programs: Nexus301 is delivered with multiple preset detection programs based on different working mode, ready to use immediately.
Easy to install and operate: with its immunity to electromagnetic interference and vibration, Nexus301 is easy to install in the most demanding environments, and the automated startup self-check make the calibration process easy, eliminating the time consuming trial and error method.




IOT system architecture enables multiple detectors connected to one network andsupports centralized security management, remote monitoring and adjustment
Embedded AI programs support live video analytics such as face capture andrecognition, and ensure alarm records with the information of passing person.
Edge computing hardware and HD cameras are configured to support AI programsrunning locally, video encoding, data storage and communication with cloudserver.
Zone display: Accurate 30 segment zone display locates the alarmed item(s) on aperson quickly making the screening process effective and improving thethroughput.
Distinguish the front and back of the body zone, and the left/middle/right zonesof body as well
Monitoring Display with friendly user interface: with 18.5inch high-definition LCD, the following information are shown: the threats object concealed zone on the body shape, the material feature of alarmed object, live video and captured photos of alarmed people.
Real-time audio and visual alerts, alongside alarm lights and detailed detection data displayed on the APP of local/remote tablet
Seamless networking with cloud-enabled system allows centralized management and third-party integration
