The aim of the "Intelligent door viewer" project is to develop an IoT door viewer that uses AI to identify familiar people, such as letter carriers, family members and friends. The notification is audio-visual. Text-to-speech can be used to make voice announcements, which is particularly helpful for visually impaired people.
Computer vision technology, AI and synthetic speech output form the software basis. Developer boards such as Raspberry PI incl. smart sensing and camera system including loudspeaker as well as networking in the sense of IoT systems represent the infrastructure.
