What is the fundus of an electronic cat? It is said that five-star hotels such as Hangzhou Huanglong Hotel are already in use. How does it work?

The electronic cat's eye structure comprises a camera and a display screen connected with the camera, and the camera and the display screen are connected with a control chip. The advantage of electronic cat's eye is to provide users with a wider angle and a larger viewing angle. On the contrary, users can freely observe more scenes around tourists without missing any details. The electronic cat's eye also avoids the embarrassment and inconvenience that traditional cat's eyes need to be observed close to the portal. Users don't even need to stop their work, just look at the display screen from a distance, and they can easily grasp the visiting information. In addition, there is a predefined delay closing function, which can set the opening time of the screen in advance, which is not only more flexible to use, but also saves electricity and energy.
