Crime is a social problem that after the confinement of COVID-19 has increased significantly worldwide, which is why it is important to know what technological tools can be used to prevent criminal acts. In the present work, a systemic analysis was carried out to determine the importance of how to prevent crime using new information technologies. Fifty research articles were selected between 2015 and 2021. The information was obtained from different databases such as IEEE Xplore, Redalyc, Scopus, SciELO and Medline. Keywords were used to delimit the search and be more precise in our inquiry on the web. The results obtained show specific information on how to prevent crime using new information technologies. We conclude that new information technologies help to prevent crime since several developed countries have implemented their security system effectively, while underdeveloped countries do not have adequate technologies to prevent crime.

Currently, video surveillance systems play an important role in ensuring the safety of citizens, their property, etc., which greatly contributes to the reduction of crime. Due to the high intrinsic value and/or high efficiency of their use for the prevention and detection of crimes, they themselves often become the objects of illegal actions (theft, damage). The main purpose of video surveillance systems is to provide continuous visual monitoring of the situation at a particular facility or territory, as well as event registration. The breakdown of the camera is detected by the loss of signal in the control center. However, the absence of a signal for reasons other than these can also be caused by an accident on the power line, a communication channel break, software or hardware breakdown of the camera itself. In this regard, there is a problem of determining the exact cause of the lack of signal and, consequently, the need for a rapid response to it. The paper proposes an approach of video surveillance arrangement according to their main functional purpose, as well as their ability to monitor each other. Based on this approach, a mathematical model of the choice of locations and conditions of location of video surveillance equipment from a set of potentially acceptable as a problem of nonlinear Boolean programming is developed. This model maximizes the functionality of the video surveillance system, taking into account the importance of areas and objects of surveillance with restrictions on the number of video surveillance of each type, the nature of the terrain and existing buildings. An algorithm for solving this problem is proposed.
