The goal of my dissertation was to develop relatively inexpensive and simple surveillance system which could be used in almost any area in order to prevent crimes. My work went on per next manner. Firstly I acquired all the necessary equipment, namely computer Raspberry Pi and webcam Logitech C270, which was then connected to the internet. Afterwards I installed operating system Raspbian and program Motion on Raspberry Pi. The results show that my surveillance system works and has some advantages, for example it is inexpensive, simple to use, it recognizes well unusual situation, which attract attention and so on. On the other hand my system has also some shortcomings, for example system has not yet been tested by multiple users and/or in different situations, also the webcam is not waterproof. All of the shortcomings can be improved in the future.
