Smart city is an interconnected system of communication and information technologies with the Internet of things (IoT), which simplifies the management of internal city processes and improves the standard of living of the population.

What makes a city smart?

– Data center. A single database will help to correlate and use different information when needed. For example, when calling 112, the rescue service may receive data on the location of the victim. And if someone fires a pistol on the street, the information can automatically come to the police along with the image of the suspect from the camera.

– Smart parking

– Smart lighting. We have already talked about street lights that turn on when it gets dark. Lanterns along transport arteries shine a little brighter after rain. This allows drivers to see the road better when the likelihood of skidding increases. Street lights are equipped with motion sensors: the light becomes brighter as soon as a pedestrian or car approaches.

– Video surveillance and photography. High-definition cameras are built into street lights and used to provide security in crowded places.

– Fire detectors. They are used in abandoned buildings where there is a risk of a fire that will affect nearby buildings. These devices contain a solar panel, a microphone and a simple communication module. When the microphone picks up the siren of a conventional sensor, an SMS about a fire is sent to firefighters and neighbors.

– Open information. This also applies to the willingness to exchange experience, and the desire to share the information received with the citizens. For example, people have access to environmental data and other statistics, including those obtained with the help of smart sensors.
