AI Binocular 3D Offline Sensor for Face / Hand Vein / QR Code

The Offline AI Binocular 3D Vision Sensor is a powerful multimodal recognition module for secure identity authentication. The module combines three recognition methods in one compact device: face recognition, hand vein recognition, and QR code scanning. Two cameras (RGB and infrared) capture 3D depth information and enable reliable liveness detection, preventing spoofing attempts with photos or videos. A dedicated system-on-chip with 0.5 TOPS NPU processes all AI algorithms directly on the module without burdening the host system.

Features:

• Three-in-one recognition combines face, hand vein, and QR code in one module
• 3D liveness detection with binocular camera prevents spoofing with photos or videos
• Offline AI processing requires no computing power from the host system
• Local storage for up to 1000 faces and 1000 hand vein templates
• Extremely low false acceptance rate of 0.001% in face recognition
• Operates in complete darkness thanks to IR illumination at 850 nm

Application Examples:

• Access control systems for offices, workshops, and secured areas
• Smart door locks with biometric authentication
• Self-service terminals in retail with payment functionality
• Time tracking systems with tamper-proof employee recognition
• Smart home integration for personalized automation
