Huawei’s M2221-FL is an intelligent facial recognition camera, with a focal length of 8 mm to 32 mm, designed to ensure high accuracy, efficiency, and stability. It integrates multiple technologies, such as image processing, pattern recognition, and deep learning, to analyze massive videos in real time, filter out useless data, and extract valuable information. It uses a dynamic facial recognition algorithm designed for densely populated scenes to detect, track, and optimize images of people. The camera can be deployed to accurately capture facial images at checkpoints, such as entrances, exits, and densely populated scenes, facilitating the move towards intelligent security.
