Camera Recording Management System
Šulc, Ondřej ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
The aim of this bachelor thesis is to create a network security system focusing on compatibility with the widest possible group of IP cameras from various manufacturers and support for remote access to records even from places outside the local network. This problem is solved using two closely cooperating applications. The first application runs on a device in the local network (in our case miniPC Raspberry Pi). The application creates the records by receiving and storing RTSP transmissions from individual cameras. It then modifies these records into a form usable for display on websites and sends the second application from which the user can access them. This application is referred to in the text as agent or agent application. The second application has a web user interface and serves the end user as a tool to manage agents, IP cameras and captured records. By principle of the application, it is important for it to be accessible on a publicly available domain. This application is referred to in the text as web or web application. The use of this architecture does not violate any of the network communication standards, which include, in particular, the initialization of communication from the network behind the NAT service.

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.

Web Browser for IP Cameras
Černý, Pavel ; Veigend, Petr (referee) ; Zbořil, František (advisor)
The aim of the work described in this thesis was to enable live video streaming from IP cameras to selected users, using simply a modern web browser with no need to install special client-side software. The solution was found by utilizing programs FFmpeg (for communication with camera and video conversion to WebM format), Stream-m (for distribution of the data received from FFmpeg to clients), and a newly-created web application built on the Spring framework, which was used to control the aforementioned programs, and also allows camera management and user authorization. The resulting system reduces the effort required for client nodes deployment and maintenance. Thanks to the image size downscaling, the system brings about a considerable reduction of data flow in the network caused by camera output, and minimizes the load on client computers.

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.

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.

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.

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.
