In this thesis, we will explore video surveillance system. Video surveillance is a necessary tool when we want to ensure a higher level of security of a particular space or location. The very basis of the video surveillance functioning is that it is about transferring visual contact from one space or location to another, in real time with the ability to view the footage backwards. Given that we live in a time of intensive technological development over the last decade, we are witnessing a significant development of different types of video surveillance that will be covered through this paper. It is also necessary to investigate the events of numerous misdemeanors and criminal offenses with elements of violence, the number of which is constantly growing, so numerous scientific studies of the perpetrator's behavior in planning the act, as well as the effectiveness of technical means such as video surveillance. Video surveillance has the status of one of the key items of technical protection primarily due to its ease of use, reliability and complete accessibility. Classic video surveillance means a system of surveillance cameras (one or more) connected to central devices through which the signals transmitted by the operation of surveillance cameras are processed. The resulting image is viewed on the screen and stored at the same time. Other categories of video surveillance that will be covered in this paper are tailored to the specific needs of their users, such as turbo cameras, network ip cameras, thermal cameras, dark fighter cameras and others.
