I own an A18R 3-D face and palm-vein recognition camera but was given no material to work with. To start development I need three things: the official user manual, the full technical datasheet, and a working sample project that illustrates how to build a custom application around the device. If you already have the original PDFs or verified scans and have written code for this model, I would greatly appreciate them. A C++ or Python example is ideal, yet I can adapt to any language that ships with the manufacturer’s SDK. The demo should cover device initialisation, enrolment, matching, and retrieval of results so I can plug those routines into my own software. Deliverables • User manual (English preferred) • Complete datasheet, including pinout, protocol, and electrical specs • Compilable custom-application demo with step-by-step build/run notes I will verify the documentation for completeness and run the sample against my camera; once it connects, captures, and returns recognition matches as described, the milestone is complete.
