In technical terms, this system includes a number of parameters. It is not only a normal appearance but also the data in the infrared range and color characteristics.
All this information allows you to accurately identify people, and even in the dark. All data is, as stated, will be processed on the device itself without transmission to the network. To analyze them is the neural network.
