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.","vendor":"DFRobot","product_type":"Biometric Vision Sensor","in_stock":true,"options":[],"variants":[{"id":15935,"title":"Default Title","sku":"DF-SEN0677","mpn":"SEN0677","price":120.45,"on_sale":false,"in_stock":true,"available_quantity":187}]}
