Description

UNIT-V M12 is an AI camera unit with M12 lens specifications and K210 processor, which integrates dual-core 64-bit RISC-V CPU and neural network processor edge computing system-on-chip, it equippes with M12 optical lens OV7740 wide-angle camera module (can replace other M12 lenses), the body is equipped with two programmable buttons and TF card expansion slot. Its bottom provides an HY2.0-4P interface and a TYPE-C interface for data connection to the controller. The UNIT-V M12 AI camera is very small, it is suitable for embedding in various devices, with machine vision processing capabilities, supporting a variety of image recognition capabilities (such as real-time acquisition of the size and coordinates of the detected target Real-time acquisition of the type of detected target), and it can perform convolutional neural network calculations, which is a low-threshold machine vision embedded solution.
