Several hundreds of cameras with built-in microphones have been installed as part of the “Safe City” system on the streets of Moscow.
The devices react to certain words and cries, as TASS reports. Video cameras can identify several dozens of artifact words in people’s speech. For example, they can distinguish the word “fire”, as well as to distinguish a normal conversation from a call for help. “The picture is visually emphasized on the main screen, and the relevant services are immediately informed” - Igor Bevzyuk, the Deputy CEO of RTI company which developed the device, said. A complete list of words detected by cameras was not disclosed. The devices are also able to respond to people with increased nervousness in behavior identified by video analytics. According to Bevzyuk, video recorders with microphones are part of the overall system of monitoring and control of urban services.
