FA51M: Embedded Biometric Module with Deep Learning, Face and Palm Recognition

FA51M is a binocular camera with a high-precision face and palm recognition module that combines image capture, template extraction and identification. The module has a built-in visible light face recognition algorithm that supports face property recognition, live body detection, face capture, face tracking, etc. 

The FA51M performs algorithm calculations at the device and can use JPG images to register directly. Combines with a rich software development interface, the integrated face recognition function can be realized in a low-configuration application platform, which is widely used in attendance, access control, passages and other fields.
