Product Overview
This ceiling-mounted UHF RFID dual-sensing access control system features an ultra-thin design with built-in antennas. It supports dense RFID reading, multi-tag identification, tag filtering, RSSI signal-strength detection, intelligent tag judgment, and audible and visual alarms.
The system can automatically record tagged items entering and leaving the monitored area. Its ceiling-mounted installation saves floor space and does not require separate external antennas.
The product is designed for RFID-based item access management in warehouses, apparel stores, enterprises, institutions, libraries, archives, hospitals, retail stores, schools, and other listed environments.
