This thesis deals with the question of electronic security systems. In the forepart are described electronic security system components such as keyboards, detectors, alarm devices etc. Various methods of security or de-security of properties, trespassing and other events detection methods, and ways of alarm calling are described there too. The next part of the master’s thesis focuses on the construction of an alarm system which is designed for security of a common-size flat with one entry. The system manages to control up to four movement detectors. The operation of the system is handled by a 16 button keyboard, and easy orientation is provided thanks to a liquid crystal display. The alarm is signaled by an indoor alert siren, however, other alarm announcing devices with an input matched for the log. 0 or log. 1 reception can be connected too. The system contains communication equipment (mobile phone) which signals alarm at a distance to the three telephone numbers. User can use a distance control by text message to unlock system or to determine its status. The system is controlled by the microcontroller AVR ATmega16, the product of Atmel company. A brief description of all components of the electronic alarm system is included in this work.
