A reference implementation of the Internet-supported home security system

There has been ultra-fast development of home electronics. Even in moderately industrialized countries, the number of applications is growing significantly. In this paper, the authors present a sample of a system, developed at the Technical University of Gdansk. Its idea is based on a home-guarded system for estates with constant Internet access. Its functionality exceeds simple alarming, and can be applied to many other aspects, such as for example child care. Special care was taken for keeping the cost of a system at a very low level, allowing it to be implemented without the need of expensive software of hardware utilities.
