The federal legislation views the prevention of juvenile delinquency and antisocial actions as very significant, since an offense is understood as an administrative offense and a criminal offense, and antisocial actions include other offenses. This issue is topical for young offender institutions; however, the special category of detainees implies a special category of crimes and violations of the established order of serving the sentence (disciplinary responsibility of convicts). By the end of 2020, there were 949 people in 18 young offender institutions. According to the statistics, the convicts did not commit crimes, yet there were more than 545 other violations. In the current circumstances, it is necessary to improve the prevention of offenses by focusing on specific activities in penal institutions, including active use of non-contact supervision over the behavior of convicts (stationary video cameras, portable video recorders, biometric identification means, access control and management systems). The researchers and practitioners are discussing the possibility of using electronic monitoring systems to supervise the behavior of convicts. This will allow a better quality of supervision over the special contingent and more effective preventive activities in young offender institutions.
