This system is equipped with six overlapping detection zones, each with alarm LEDs that display the exact position of detected metal. With four emitters paired with opposite receivers, it ensures complete coverage without blind spots. The adjustable sensitivity of each zone (0 to 255) allows fine-tuning to avoid interference from harmless items like coins, keys, or belt buckles. A built-in statistics function records both the number of people passing through and the number of alarms triggered, while parallel operation capability allows multiple gates to work side by side (maintaining at least 40 cm distance) to handle large crowds efficiently.

To complement its core functionality, the system includes intelligent and user-friendly enhancements. It offers remote upgrade and control options via internet technology, along with detailed statistics logging for both pass-through and alarm events. A real-time query function provides quick access to system information, and intelligent partitioning allows users to adjust detection zones based on specific needs. Optional PC terminal connectivity enables real-time configuration from any location. The unit features four infrared modes—IR ON, IR OFF, front group IR ON, and back group IR ON—and includes 72 preset application scenarios that automatically adjust zones and sensitivity. It is fully safe for individuals with pacemakers, pregnant women, and magnetic media such as floppy disks and recording tapes.
