## Description

This standalone vision module combines face recognition, palm vein recognition and QR code decoding in one compact sensor. It uses dual colour and infrared cameras with onboard AI processing, so recognition happens locally without needing cloud access or host-side computation.The binocular RGB + infrared camera system supports 3D liveness detection to help reject photo and video spoofing attempts. Recognition results are sent over a simple UART serial interface, while the USB interface supports UVC video transmission so the module can also provide a video stream.It is suited to secure access control, smart door locks, smart home systems and self-service terminals. DFRobot provides a Product wiki and Development Manual, and the package includes the sensor, a 1.25mm 4-pin to Dupont female connector cable and a USB data cable.Features:Binocular 3D liveness detection resists spoofing via photos/videosNeural network-based algorithms: face recognition, palm vein recognition, QR code decodingLocal storage: 1,000 faces + 1,000 palm vein templatesOperates in complete darkness and non-direct sunlight outdoorsZero host-computation requirement; all AI processing occurs offline on-moduleSpecifications:SoC: Arm CPU@900MHz, NPU@0.5TOPS, RISC-V@600MHzDDR2: 64MBFlash: 32MBCameras: Dual 1/5” CMOS, 2MP, dual MIPI interfacesLens: FOV: 83° diagonal; optimal focus: 60cmLED: IR@850nm, RGB@650nm (90° illumination)USB: UVC video transmission (expandable to UAC); MJPEG output (H.264/YUY2 expandable)Communication: UART@115200 baudSupply voltage: 5-12VOperating current: 320-330mA@8VStandby current: 120–130mA (auto-detection mode)Shutdown current: 0µA (non-auto-detection mode)Operating temperature: -20°C to +60°CStorage temperature: -30°C to +70°CHumidity: 10–93% RH (non-condensing)Audio I/O: Expandable (speaker/microphone)Boot time: 900ms–2.5s (varies with stored user count)User capacity: 1,000 faces; 1,000 palm veinsAlgorithms: Binocular liveness detection, deep learning face recognition, palm vein recognition, QR code recognitionLiveness FAR (False Acceptance Rate): ≤1%Liveness FRR (False Rejection Rate): ≤1%Face recognition pass rate: 98.85%Face recognition FAR: 0.001%Recognition angle: ±20° pitch/yaw; supports multi-angle enrollmentFace detection range: 30–120 cmPalm vein / QR code detection range: 15cmDimensions: 57.8×20×10.12mmA strong choice for makers and integrators building biometric access, payment, attendance or AIoT projects where offline recognition and simple serial integration are important.
