Product Overview
The HOMSH MD31 Iris Recognition Module is a compact USB-based iris
coding and recognition module, leveraging the independently
developed third-generation Phaseiris™3.0 iris recognition
technology. It enables iris capture, recognition, and matching
(local/remote/template/image matching) within a 370mm~500mm working
distance. With a compact form factor (80mm×24mm×25mm), it allows
easy integration into smart door locks, intelligent cabinets,
access control systems, and other intelligent terminal devices,
delivering secure and efficient identity authentication.The
quantity for this specification is 5000.
Core Functions and Technical Features
1. Full-Process Iris Recognition & Matching
The module integrates a complete iris recognition workflow:
● Iris Capture & Recognition: Utilizes an 850nm imaging band to
capture high-quality iris images that meet iris database standards,
with Phaseiris™3.0 technology enabling precise feature extraction.
● Multi-Mode Matching: Supports local matching, remote matching,
template matching, and image matching; also enables both offline
and online iris comparison.
● Dual Comparison Modes: Allows comparison of image data and
template data, catering to flexible application scenarios.
2. High-Performance Imaging & Algorithm
● Advanced Camera Module: Captures images at a 640×480 resolution
with a 25 frames/s rate (pixel depth: 8 bits/pixel), and achieves a
spatial resolution of >4.0 Lp/mm (>16 Pixels/mm) to ensure
clear acquisition of iris textures.
● Industry-Leading Algorithm Accuracy:
False Accept Rate (FAR): 10−7
False Rejection Rate (FRR): 10−3
Encoding speed: 20 pictures/second; Comparison speed: 10,000
templates/second.
● Compliance with Standards: Algorithm performance meets
GB/T20979-2019 "Information Security Technology Iris Recognition
System Technical Requirements"; image quality complies with the
GB/T 33767.6-2018 iris image data standard.
3. Hardware Specifications & Environmental Adaptability
● Compact & Efficient Design: Dimensions: 80mm (L) ×24mm (W) ×25mm
(H); Power consumption: <4W; Connection: USB 2.0 (with an SDK
provided for secondary development).
● Wide Working Range:
Working distance: 370mm~500mm (supports optional VCM lens for
precision adjustment).
Light intensity: 0~6000 Lux; Humidity: 0–93% RH.
Temperature tolerance: 0℃～45℃ (standard operating range) / -10℃～55℃
(wide operating range).
● Eye Safety: Conforms to IEC 62471 "Photobiological Safety of Lamps
and Lamp Systems".
4. Storage & User Capacity
● Multiple Storage Versions Available: Offers different storage
capacity versions, supporting user storage for 500, 1,000, 2,000,
5,000, or 10,000 people, flexibly adapting to diverse needs from
small-scale access control scenarios to large-scale systems.
Typical Application Scenarios
Leveraging its high accuracy, compact size, and wide working range,
the MD31 module excels in:
● Smart Access Control: Smart door locks, office and building access
systems (the 370-500mm range enables convenient "stand-and-scan"
operation).
● Intelligent Cabinets: Confidential file cabinets, medical supply
cabinets, and tool management cabinets (ensuring secure access
through iris authentication).
● IoT Terminal Integration: Embedded into handheld devices,
self-service kiosks, or industrial terminals for identity
verification in sectors such as finance, healthcare, and industry.
