Security system with mobile phone communication
Ulbrich, Jakub ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
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.

Module of electronic security central with Ethernet communicator
Strašil, Ivo ; Pust, Radim (referee) ; Burda, Karel (advisor)
This diploma thesis deals with a design of a burglar alarm control panel, equipped with an Ethernet interface. The thesis contains a discusson of present solutions of control panels and of present usage of Ethernet communication. An idea of sensors, directly connected to LAN, was discarded on basis of a component price survey. Finally, a new concept of the panel has been chosen. This concept allows a free definition of internal logic using a C-like scripting and provides a possibility to create a network of these panels in a LAN network, using a software-only supervising main control panel. A new control panel following this concept was designed and succesfully tested.

Wireless IR sensor for space intrusion detection
Možný, Radek ; Krajsa, Ondřej (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis deals with design of wireless space breach detection sensor using sensor HC-SR501 and communication module SI4432. In thesis emphasis is on design of device with as low power consumption as possible using sleep modes of microprocessor Atmega328. Thesis includes desighn of temperature measurement, battery state measurement and subsequent broadcasting of gained information to receiving base station. Task of basae station is to evaluate information and among other things decide whether or not is guarded space breached. Two sensor network is further elaborated when sensors are sending periodical notification, person detection alarm, sensor manipulation alarm or warning about low battery state. Base station has regimes guarded and unguarded .

Guard System for Household with Usage of GSM Communication
Křesal, Tomáš ; Drahanský, Martin (referee) ; Hájek, Josef (advisor)
Theme of the Bachelor's thesis is the issue of security of households. Discusses the current methods of protection, of their typical characteristics and shortcomings. Based on information gathered from the opening chapters is designed and engineered an electronic security device with alarm transmission to the mobile phone. Remote control of electrical appliances and supervision households via the Internet extends the applicability of the system. The conclusion of this work is devoted to the hardware implementation of the proposed security system. Software implementation is not discussed here and will be part of further development.

Implementation of Burglar Alarms in Smart Wiring Systems
de Groot, Štefan ; Krajsa, Ondřej (referee) ; Strašil, Ivo (advisor)
The thesis deals with technical and legislative possibilities of realization an electronic security system by components of intelligent electrical installation. In this thesis there are described common types of connection detectors to the installation, requirements for IAS units and depending on these facts, there is the demo panel designed and fixed by buttons, lights, thermoregulation unit, motion detectors, control unit and modules required for maintenance of present components. This system contains standard components of intelligent electrical installation, which in secure mode carries the duty of the IAS system. Output of this thesis is also laboratory exercise demonstrating possibilities of this system. It contains transparent instructions for putting this system into service and a batch of tasks, which will lead student over basics of programming in development environment Mosaic and optimization of the system for specific situations.

Utilization of technical and informaticalservices for protection of property and individuals at schools
Reindl, Filip ; Lustig, František (advisor) ; Stejskal, Martin (referee)
TITLE: Utilization of technical and informatical services for protection of property and individuals at schools SUMMARY: The objective of this work is to deal with problematic of security systems and their possible use at school buildings. It summarizes the current legislative on the field of security systems and in particular the protection of personal data and explains the principles of function of security systems. The main emphasis is on electronic fire alarm system (FS), electronic security systems (ESS), electronic access control (ACS) and closed-circuit television (CCTV) components in terms of hardware, communications and data utilization. The work also includes a model of practical comprehensive security system design for actual school building. KEYWORDS: Functions, systems, FS, ESS, ACS, CCTV 4
