Product Overview
The iD Multimodal Smart Access Control is a high-performance biometric gate designed for coal mines and other high-risk industrial environments. Powered by a Rockchip processing engine, it supports face recognition, iris recognition, and combined face-plus-iris identification. With an exceptionally low false acceptance rate and false rejection rate, the system delivers reliable personnel identity verification and access management even in the harshest underground conditions.
Product Description
The iD Multimodal Smart Access Control addresses one of the most critical challenges in underground mining safety: ensuring that only authorized personnel enter restricted areas. By combining dual-modal biometric identification — iris and face — into a single integrated terminal, this system eliminates the vulnerabilities of single-factor identification methods such as RFID cards or PIN codes, which can be shared, lost, or stolen.
At the core of the system is a proprietary iris recognition algorithm that achieves a false acceptance rate (FAR) as low as 0.00001% and a false rejection rate (FRR) of just 0.1%. This level of accuracy is essential in mining environments where unauthorized access can lead to catastrophic safety incidents. The dual-eye iris capture device completes image acquisition within 2 seconds, while both iris enrollment and recognition take less than 1 second each, ensuring smooth traffic flow at access points without compromising security.
The intelligent pitch algorithm automatically adjusts the capture angle to accommodate personnel ranging from 1.4 m to 1.9 m in height, eliminating the need for manual positioning and making the system accessible to virtually all workers. An infrared supplementary light operating at 785–835 nm ensures stable recognition performance across varying lighting conditions, from bright surface areas to pitch-dark underground corridors. The system supports both standalone and networked deployment modes; in networked mode, it can match against databases of up to 20,000 enrolled individuals, making it suitable for large-scale mining operations.
The terminal is available in both handheld and desktop form factors, providing deployment flexibility for different access control scenarios. Iris comparison supports both 1:1 and 1:N modes, and the iris image resolution of 640×480 ensures high-quality biometric data capture. With a working humidity range of 0–93% RH and an operating temperature of −10 °C to 55 °C, the device is engineered for the demanding environmental conditions typical of mining facilities.
