Technology for webcast
Švehlák, Milan ; Číka, Petr (referee) ; Zeman, Václav (advisor)
This bachelor´s thesis discusses technology for creating webcast and possible methods for its implementation. To begin with, there is mentioned theoretical knowledge about the transmission of multimedia over the Internet. This is followed by a list of basic methods for webcast. In the following parts, these various methods are described in detail with their advantages and disadvantages and they are compared. This thesis also discusses the hardware and software tools necessary for implementing the webcast. Finally, there is a design suggestion for the most appropriate method for making a webcast with respect to the stipulated requirements and subsequently made its implementation.

Web portal for the video transmission from IP cameras
Čučka, Milan ; Doležel, Radek (referee) ; Zeman, Václav (advisor)
This work is about methods for transferring an image from the web cameras, IP cameras and the creation of a live transmission of television cameras with streaming server and subsequent placement on the web. The first part deals with basic methods of webcam image transfer. This information is described in detail, in next section. The third section describes using of IP cameras for live broadcasts or transmission to a common frame. The last section describes creation of a streaming server and the process of creating a live transmission. There are the advantages and disadvantages of each technology. At the end of the work is given the most frequently used multimedia data formats.

Potentials of camera connection to PC computer
Pelc, Lukáš ; Růčka, Lukáš (referee) ; Herman, Ivo (advisor)
Bachelor thesis deals with the possibilities of network cameras and their connection to a PC. Network cameras are analyzed in terms of internal structure, external structure and aspects of their use. Communication with the PC and the user is provided with a communication interface and control software. The most important function in the use of network cameras is their output – a video. It is composed of several individual factors, such as the encoding method, compression and frame rate. The theory is applied in practice as proposed by the best camera, the method of connection and programming of custom control applications in the Java programming language.

IP Cameras Control Library
Schmied, Jan ; Rozman, Jaroslav (referee) ; Luža, Radim (advisor)
This thesis describes the design and implementation of a library that allows control of IP cameras and receives multimedia streams. The thesis briefly introduces standard interfaces of IP cameras and describes in detail VAPIX interface. This interface is also demonstrated by examples. The practical part deals with the design and implementation of the library using the FFmpeg and cURL libraries. Library is subject of a measurement that shows its performance.

Robotic Arm - Navigation by Using Axis 214 Camera
Skládanka, Josef ; Hanáček, Petr (referee) ; Zbořil, František (advisor)
This paper is focused on recognizing the position of a cube placed in the working area of the robotic arm Mitsubishi Melfa 6 SL, using digital image from Axis 214 cameras. It briefly describes few techniques which can be used for detecting the position of an object in the image. The main focus is laid on the implemented method, which detects and analyses gaps in the grid plotted in the robot's working area.

Monitoring and Security System
Felix, Martin ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This master's thesis deals with design and implementation of system for securing and monitoring objects. The whole system is serving as an application getaway between typical TCP/IP network and heterogeneous network containing different end devices such as security cameras, microphones and some sensors (e.g. for temperature measurement). In case of detected event, the notification is created, recorded and the user is informed via administrative front-end. System can be managed from remote location and data from devices can be shown by web interface. Theoretical part of this project concerns with the analysis of different types of connecting devices and sensors and the possibilities of their usage for the monitoring systems along with description of communications protocols for each end device. The next part deals with the cameras interfaces, content analysis and connectivity with central server. Practical part describes methods and techniques used for implementation of system.

Android IP Camera
Chvála, Jan ; Havel, Jiří (referee) ; Herout, Adam (advisor)
The goal of this thesis is to design a system which would allow video data streaming from a mobile device and real time playback using a standard web browser. The technological background and the implementation platform are both part of this thesis. Web Real Time Communications (WebRTC) technology was used for acquiring multimedia data on mobile device. This technology is natively supported in the latest major web browsers and in WebView component (Android version 5.0 and above). Sending push notifications from a server to a mobile device to start the streaming is done with Google Cloud Messaging technology. The resultant system allows a user to start the application on mobile device with easy web browser access. This starts the multimedia stream from device, which can be parametrized and secured by password. The benefit of this thesis is the overview of WebRTC technology and its demonstration. The IP camera implementation shows how easy it is to use the WebRTC in real applications.

Security system using mobile networks
Svoboda, Adam ; Wieser, Vladimír (referee) ; Hanus, Stanislav (advisor)
This master´s thesis deals with design of security system, which transmits captured video using mobile systems. There are chosen representatives of cameras and motion sensors that could be used in the construction. The thesis also deals with the theoretical design of the transmission system, which consists of a camera, a motion sensor, an USB modem and a microprocessor, that manages all operations. There is also a proposed block diagram of a communication method. The security system is designed and tested in various conditions.

Technical project for a camera system i a mountain hotel offering digital and analoque camera alternatives
Tománek, Jiří DiS ; Kos, Jiří (advisor)
The thesis deals with a project of camera observation system for a mountain hotel. The project design goes from the enclosed lay-out plans of the building and from the camera system's requirements. It describes the solutions with analog CCTV cameras and with digital IP cameras. Graphic instruments as a Digital Video Recorder for analog system and as a high-powered computer for digital system are optimised to the number of cameras and the requirements on recording. The thesis describes all hardware and software used for execution of the project including the setting and bonding. The costs of single options and time needed for execution of the project are displayed in charts. The final part of the thesis explains the designed camera systems and their costs and describes their advantages and disadvantages.
