In the discussions around smart cities – there are different types of sensors to more efficiently manage city resources – the role of audio can sometimes be overlooked. Audio is often used as a valuable complement and even an alternate to cameras or other IoT sensors in cities. Selecting a contemporary connected audio system can make sure that important communication takes place at the proper time, within the right place and with the sound quality needed to stay citizens safe and secure. Here are three principal scenarios when audio solutions can contribute to a better and safer city:

1. Sound detection

Many security incidents during a city are preceded or initiated by some quite noise, for instance, aggressive behavior and raised voices, gunshots or breaking glass. Today’s solutions can automatically detect and recognize pre-defined sounds and send alerts for potential and real incidents as they occur. Surveillance cameras together with sound detection capabilities can add great value to security systems covering public spaces, sort of a park or square. the mixture of sound and video is often a strong solution to both detect and verify a situation, and enable quick, relevant action to attenuate the results.

2. Emergency announcements

Each year many cities are exposed to emergencies, like natural disasters. In situations like this, it’s important to tell citizens as soon as possible and guide them to stay people safe. With audio speakers its possible to succeed in people in selected zones quickly and effectively. The audio announcement systems are often installed to organize cities for emergencies. within the case that something happens, it’s crucial to possess a reliable and dealing system. With the proper network speaker solution, the condition of the system and audio quality is under full and constant control, ensuring that messages are delivered as clearly as is important for an emergency.

3. Prevent crime

Having enough resources to keep a city safe is a common challenge in cities all over the world. A lot of cities are working with a surveillance system to monitor the city and manage law enforcement resources most efficiently. With video, we can detect crimes such as intrusion into buildings or restricted areas, but in many cases, police or guards will not reach the location in time to prevent theft or vandalism. By implementing video surveillance in combination with an audio solution, the camera can prompt an automated audio warning to the intruder, or alert a security guard to give a live warning directly to the intruder using the audio system. In many cases, this type of warning is sufficient, preventing the need for additional security measures. The safety and security of citizens are often highlighted as one of the most important aspects of livability in a modern city. With authorities increasingly looking to use connected technology to improve their cities, it is a combination of different sensors and devices that offer the maximum potential, and audio can play a central role.
