Deals with the design of a special security system in which, apart from the usual parts such as camera and motion sensor, a USB dongle will be used to send the recorded videos via UMTS or LTE mobile networks to the server where they can be viewed. Nowadays, when mobile operators offer unlimited tariffs and high-speed internet, this solution is very advantageous because we are not limited by the length of the Ethernet cable that we have to connect to the camera or the range of the Wi-Fi router when installing the camera. The only condition is that the area is covered by a high-speed Internet operator.
The aim of this thesis is to study the possibilities of transmission of video signals in nationwide mobile networks GSM, UMTS and LTE, as well as formats of output video signals from cameras and types of sensors for motion indication. Based on this knowledge, a block diagram of a system for monitoring the disruption of space with a focus on video transmission is proposed.
The entire system will be controlled by the Arduino YUN development board, which has a USB connector for the Huawei E398 modem and an Ethernet connector for any IP camera. If the motion sensor detects motion, the microprocessor sends a video recording request to the camera to the SD card. The time the video will be recorded will be optional in a program that is also part of the work. Once the video is stored in a compressed format on the card, it is sent to the remote FTP server via the modem where it will be available to the user.
The thesis consists of four main parts. The first block is devoted to the theory of motion sensors, their distribution and specific types available in shops, the division of cameras according to the type of sensor, the codecs they use, or the image resolution. Again, a few representatives are selected in the shops and analyzed. The last part of the first block is devoted to mobile communication. There are described individual mobile standards and USB modem Huawei E398, which is used in the thesis. The second block is devoted to a more detailed description of microprocessor communication with individual parts of the security system. There are individual operations needed to communicate with the camera, get the video from the camera in the required format or synchronize with the internet time.
The following is a detailed description of how to save a video to a memory card and then copy it to a remote server. Part of the thesis is also a program for working with videos that are already uploaded on a remote server and a detailed description of its function. The third block summarizes the testing of the security system, the speed of sending data, and comparing the quality of the video sent to the video server captured by another recording device. In the last block is described in detail the installation of the security system. There are individual steps leading to the correct functioning of the whole security system and a photograph of the complete connection.
