The 2 megapixel face recognition machine (binocular) uses the advanced neural network algorithm (CNN), which is a product after tens of millions of algorithm training. It integrates the functions of image acquisition, face detection, face tracking, face comparison and living body judgment. The recognition rate is high and the recognition speed is faster. The off-line dynamic portrait recognition binocular machine does not need the special cooperation of pedestrians, does not need the computer control, is easy to use, simple to install, and is comprehensively ahead of similar products in the industry. It can be widely used in community access control, gateway, office building and other scenes.
