Evaluation of pasive detectors in intrusion and hold-up alarm systems
Kalivoda, Petr ; Hart, Jan (advisor) ; Libich, Ladislav (referee)
Thesis deals with passive safety elements . The issue is dealt with in the theoretical part and
a practical part . In the theoretical section provides information used for introduction and its
current development . The practical part deals with the principles of magnetic -synaptic
contacts , their reliability and proper functioning . It adds an option for simple - holding .
Shown are the practical experiments from laboratory measurements to clarify the issue of
magnetic contacts and compare actual values with the theoretical values indicated by the
manufacturer . Finally, we evaluated the results of the work

Analysis and evaluation of the current motion detectors
Suchý, Jakub ; Hart, Jan (advisor) ; Lešetický, Jan (referee)
This thesis is thematically focused on current motion detectors in an intrusion and hold-up alarm system. The aim of this thesis is evaluation of the selected motion detectors according to specified criteria. This criteria predicates about quality of security that provide detectors (sensor, optics, processing, antimasking, reach, radius, installation height, certification) and the cost of the acquisition detectors (price). This thesis is evaluated by methods of Multi-Criteria Analysis. The values of the weight are determined by Ranking method. The order of the options is determined by Weighted sum Approach. The final order of evalueted detectors was compiled based on the results.

Evaluation of vehicle security systems
Škach, Dominik ; Hart, Jan (advisor) ; Kotek, Tomáš (referee)
The aim of this bachelor thesis is to valorize a car security systems. Firstly it is discribed mechanical locking of vehicles, where is possible to find instructions how to lock various components of the car. The next chapter is a description of car electronic security. There is described how detectors, alarm and emergency systems work. There is also intention to permanent vehicle identification systems and GPS searching systems. Practical part of bachelor thesis is focused on comparing three specific vehicles. There is also comparision between electronic security from production and between additionally installed security.

Comparison of biometric identification systems of the financial and user perspective
Štekerová, Veronika ; Hartová, Veronika (advisor) ; Hart, Jan (referee)
This bachelor thesis deals with comparing identification systems of the financial and user perspective. The first part of the bachelor thesis deals with history of each selected biometric systems. There were selected those four biometric systems: 3D facial scans, fingerprint scans the eye and hand geometry. Furthermore, the thesis explains the concepts of identification and verification, to avoid confusion. Subsequently, the selected biometric methods are described and explained on what principle works. In the practical part were chosen specific individual readers of biometric systems. Based on their evaluation of the user and the financial individual readers compared to each other. For clarity, have been created tables with technical parameters of individual biometric readers. For the evaluation was created a table with specific parameters and using multi-criteria analysis has been selected user and financially friendliest biometric reader.

Comparison PZTS of the financial and user perspective
Košťák, Martin ; Hart, Jan (advisor) ; Hartová, Veronika (referee)
The aim of the thesis was an evaluation of the security alarm and emergency systems of financial and user perspective. The thesis was focused on familiarization with problems of these systems. The overview solved problems was dedicated analysis of data loggers of each type. Their advantages and disadvantages were given for installation and use. In this part were also discussed the most commonly used detectors, security alarm and emergency systems. In the custom processing was solved the evaluation of selected data loggers and the solution was to select the most appropriate of data logger for use in financial and user perspective.

Recognizing people using esoteric identification
Pohanka, Milan ; Hartová, Veronika (advisor) ; Hart, Jan (referee)
The bachelor´s thesis deals with the issue of esoteric systems which belong to biometric systems. The first part of the thesis contains a basic introduction to the characteristics and dividing of biometric systems. From the biometric systems there are chosen five methods, in which are described the basic characteristics and principles of operation. Furthermore, in the thesis are assessed security risks of biometric systems in general and esoteric identification systems. There are also evaluated user aspect of the esoteric systems, which is an important part of their application in practice. The final evaluation is the economic´s one, in which is assessed the economic aspects in general, afterwards there are evaluated the finger vein recognition devices and then there is compared the prize of the three different devices: One of the area of the esoteric systems and two more, which from the biometrics methods are commonly used in the market.

Analysis of security risks of I&HAS from the user and installation perspective
Mrózek, Jan ; Hart, Jan (advisor) ; Hartová, Veronika (referee)
The master thesis discusses the issue of intrusion and hold-up systems. It deals with basic division of particular kinds of protections, detectors and their functions, panels and their types. Especially it discusses detector security risks and the risks due to improper installation.
The next part deals with the multi-criteria analysis options where the panels of several manufacturers are compared and evaluated so we get the best panel in the price/performance ratio.
Then we measure magnetic contact and their maximum distance between two parts of this magnetic contacts. Two hypotheses are given, which approve or disprove the claims of the manufacturer. According to the measured and calculated values it is demonstrated hypothesis that refuses the claims of the manufacturer.

Analysis of wireless transmissions in I
Hrobařová, Zuzana ; Hart, Jan (advisor) ; Hartová, Veronika (referee)
This dissertation deals with Intrusion and Hold-up Alarm System wireless communication (I&HAS). The main objective is to determine security risks of wireless communication between detectors and PBX, eventually to recommend how to avoid these risks. The research was conducted on different detector types. The first theoretical part of dissertation describes variety detector types, wireless communication types and theoretical security risks of these communications. The practical part of dissertation describes the above mentioned security risks investigated in practice as well as the measurement of communication between detectors and PBX. The recommendations how to avoid these risk are placed at the end of dissertation.
