Product Overview
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.

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.
