This thesis deals with complete theoretical design of security system for a family house, from the selection of technologies, security principles and selection of elements, theoretical suggestions of their placement to practical realization. I this thesis, securing of entry points, such as doors and windows, is done by magnetic contact sensors. Windows are secured also against breaking of glass. Inner space is secured using motion sensors. Further, the function principle of optical latches as secondary securing element of inner space is explained. The designed security system implements a central control unit, which is able to provide status information on all security elements to the host system. IQRF wireless communication operationg in licence-free is used for communication among elements of the security system. GSM SIM9000 module is used for communication with the security system.
