Smart doorbell

V diplomskem delu se opisuje izdelavo pametnega zvonca, ki omogoča pogovor med mikroračunalnikom Raspberry Pi in aplikacijo za operacijski sistem android ter komunikacijo z videokamero. Komuniciralo se je preko tehnologije VoIP, ki omogoča prenos komunikacijskih podatkov preko internetnega omrežja. Zvonec vključuje videokamero, ploščico ReSpeaker, na kateri sta dva mikrofona, ter priključek JST 2.0, na katerega je povezan zvočnik. Vse te dele povezuje mikroračunalnik Raspberry Pi 3 Model B+. Pametni zvonec se je bilo testiralo na večih lokacijah, ki so imele različno moč signala brezžičnega omrežja.We explain the smart doorbell system, implemented on Raspberry Pi microcomputer and android application. The doorbell streams the video and displays it in real time in the application. The communication is supported by VoIP technology, which delivers voice communications over the internet. Doorbell consists of a video camera, ReSpeaker 2-Mics Pi HAT board, which also includes a JST 2.0 connector used for our speaker. All the components are controlled by the Raspberry Pi 3 Model B+ microcomputer. The testing of the product was done on various locations. They differed in the strength of WIFI signal
