This work introduces a general view on an evolution of door communication systems. The work evaluates a current market of IP-based systems which currently consists mainly of more expensive devices targeted on business customers. The goal is to design a doorphone prototype based on an IP protocol with suitable functions and easy control for a less demanding user. The Raspberry Pi computer was chosen for development together with other suitable hardware to accomplish desired functions. The Linphone open-source project was used to implement phone functionality. The low price or open-source solutions were preferred when selecting ideal hardware and software to use. The conclusion evaluates how successful the implementation was while keeping the device affordable.
