Phase-Trajectory Identification
The system analyzes RFID tag phase trajectories to determine whether tagged items are entering or leaving the monitored area.
Simultaneous Entry and Exit Detection
It can distinguish entry and exit directions when multiple RFID tags move through the access area at the same time.
Stray-Read Filtering
The system controls unintended RFID reads around the entrance and supports up to six EPC filtering rules.
No On-Site Direction Adjustment
The page states that the device can be used after installation without repeated on-site direction or parameter adjustment.
Multi-Tag Processing
It supports batch RFID tag reading and writing, with a stated identification speed of more than 500 reads per second.
Ceiling-Mounted Design
The device can be installed on the ceiling using a top-mount bracket, side-mount bracket, or suspension cable, without occupying passage floor space.
Audible and Visual Alarm
A built-in buzzer and red-and-blue light strips can be controlled for audible and visual alarm notifications.
Operating-Status Monitoring
The system supports access-control operating-status reporting and can automatically report internal hardware component faults.
This AI-powered ceiling-mounted UHF RFID access control system uses an ultra-thin structure with multiple built-in narrow-beam antennas. Based on AI algorithms and a multi-transmit, multi-receive mechanism, it analyzes RFID tag movement and identifies entry and exit directions in dynamic multi-tag environments.
The system determines entry and exit status by analyzing RFID tag phase trajectories. It does not rely on signal strength, infrared sensors, radar, or visual recognition for directional judgment.
It supports simultaneous entry and exit identification, stray-read filtering, batch tag processing, ceiling installation, audible and visual alarms, offline data retransmission, and communication through TCP, HTTP, and MQTT.
UHF RFID
The stated identification speed depends on tag performance and orientation, item material and quantity, and movement speed.

Frequently Asked Questions
How does this RFID access control system determine entry and exit direction?
It analyzes RFID tag phase trajectories and the movement process of tags to determine whether tagged items are entering or leaving.
Does it require infrared sensors, radar, or cameras?
No. The page states that directional judgment does not depend on infrared sensors, radar, visual recognition, or signal-strength-based judgment.
Can it identify multiple tags entering and leaving simultaneously?
Yes. It supports multi-tag processing and can distinguish entry and exit directions when multiple tags move through the monitored area together.
What passage width can the system cover?
It supports a passage width of up to 3 m without auxiliary antennas and up to 6 m with two additional auxiliary antennas.
What communication protocols does it support?
It supports TCP, HTTP, and MQTT, with wired Ethernet as standard and Wi-Fi available as an option.
Does it support cloud management and offline data retransmission?
Yes. It supports MQTT-based centralized cloud management and can retransmit stored data after a network interruption.
