When talking about cameras used in city, we used to think about those cameras for capturing drivers who break traffic rules. But now, artificial intelligence-enabled cameras and sensors can keep an eye on the surroundings to monitor and police the city, and in turn enhance the security level in the city. Actually, Chinese are now living in a world that is built with the largest and most sophisticated camera surveillance system. Artificial intelligence cameras are in widespread use across the whole country.
One example of the use of AI camera is when it is applied to detect a traffic junction about its real-time conditions like crowd density, vehicle density and even the walking speed of pedestrians. These real-time data can be accessed accurately. If a junction is too crowded, policeman would come to that spot to maintain order to avoid incidents like stampede happen. This technology is based on deep learning and techniques for computer visions. The real-time monitor and statistical data of the place makes “smart judgements” about whether the place is overly crowded or if it has abnormal gathering of crowds.
Another situation where ai cameras are used is when someone sneak into a “sensitive” or “prohibitive” area and think he or she will not be found because no one is there. In a circumstance like this, the ai camera “knows” you and recognizes you and there is no need for a living person to be there, because on the other side of the camera, every move of yours and even the look in your eyes are clearly seen on the screen by policeman. Through deep learning in the characteristics and movements of human body, this recognition system can automatically detect and mark the spot of someone. When someone abnormally enters a prohibitive area or has some abnormal actions, the system can automatically release warning. A very similar example is when someone is acting abnormally, the warning system can smartly detect whether people are conducting some fast activities or fighting with each other and give off alert to the background.
These are just a few examples of how ai cameras are now applied in real life situations to build a safer, smarter and more efficient city. AI in smart cities development can play a crucial role in urban planning, development and management with things like advanced security systems and traffic monitoring. The implementation of AI in real life is actually more ubiquitous than ordinary people can imagine. The life we are now living in which crimes or illegal events are rarely seen perhaps is not the result of “no dangers for real”, but rather it is the result of the fact that we are now living in the full surveillance of all kinds of lens and cameras whose duty is to provide for us that kind of safe environment. But at the same time, all of our information, whether personal or not, can be fully grasped and kept by the city to be used in ways we are never able to think of. It is true that we are living in a safer environment thanks to technology, yet this camera surveillance network, will it become something that we will never ever be able to escape from either in the near or far future?
