Domovní interkom pro více účastníků s pokročilými funkcemi

Abstract

This thesis presents the design and implementation of an open-source intercom system based on Raspberry Pi. The aim is to create a solution that enables voice communication between the Master Unit and the Client Units using the SIP protocol and the Asterisk software PBX. The system supports mobile phone notifications, remote door unlocking and wireless communication via Wi-Fi, which enables installation even in locations without established Internet cabling.

The work focuses on the installation and configuration of a Raspberry Pi device, a Linphone SIP client and the Mosquitto MQTT broker, which is used to control the door relay and provide notification reception. There is also a focus on security, with communications encrypted using TLS. The solution includes a web application for establishing calls with the Client unit. The individual components are housed in custom-designed and 3D-printed protective enclosures.

This open-source system presents an alternative to conventional communication solutions and offers customization and expansion options according to the specific needs of users.
