“…The rate of common crimes (especially ones against property) in the zones located further away from police stations could be balanced out by an effective CCTV system. In some Polish cities (including Łódź), studies determining the usefulness of installing industrial cameras to improve public safety were conducted (Waszkiewicz, 2012;Matczak et al, 2021). Although it was expected that the CCTV cameras would reduce crime rates by "expanding" the police supervision of critical locations, the results were not optimistic.…”

The goals of the study presented in the article draw attention to the role of public transport stops in the spatial distribution of crime in the Stare Bałuty estate in Łódź, Poland. Answers are provided to the questions of spatio-temporal structure of criminal acts committed within the estate, the influence zone of transport stops as well as the assessment and effects of environmental crime predictors in their vicinity. Crime location quotient (LQC) was used to assess the intensity of crime and identify the influence zone that attracts certain categories of crimes to the vicinity of stops. The influence of environmental predictors on the level of threat was identified and assessed on the basis of B. Czarnecki’s method. The variables used in the analysis initially spanned 739 crimes and 53 public transport stops evaluated with regard to 20 safety aspects and their impact on the pro-crime effects on the scale of location as well as various forms and functions of urban development. A strong negative influence of public transport stops ‒ attracting various categories of crime, mostly property theft ‒ was discovered. The negative influence of stops on the concentration of crime within 200 metres is reinforced by the existence of environmental crime predictors. The recommendations and discussions resulting from the findings should influence the policy of crime prevention on the level of object location, management and the maintenance of socio-spatial order in the vicinity.

“…El auge tecnológico, ha contribuido en diversas investigaciones que han demuestrado el valor de los sistemas de videovigilancia como mecanismo de disuasión en la seguridad de espacios públicos y privados (Matczak et al, 2023), sin embargo, este efecto debe ir acompañado de canales de comunicación que permitan la interoperabilidad de las redes de seguridad (Jaffe y Pilo, 2023).…”

“…A pesar de estas preocupaciones, existe un consenso sobre el potencial que poseen los sistemas de vigilancia y su valor para reducir el crimen y el temor al delito, como España (Hino, 2022), Polonia (Matczak et al, 2023) y el Reino Unido (Lawson et al, 2018), especialmente cuando se enfocan en áreas de alta incidencia delictiva, conocidas como "hot spots".…”

El objetivo de la presente investigación fue hacer una descripción sobre las herramientas tecnológicas que se emplean para la prevención del crimen, considerando que las estrategias policiales priorizan el patrullaje a través de sistemas de drones, de videovigilancia y uso de inteligencia artificial en determinadas jurisdicciones y/o zonas geográficas y en muchos casos, ha facilitado la identificación y captura de delincuentes. Con respecto al uso de drones, se emplean para el patrullaje y vigilancia ciudadana; por su parte, los sistemas de videovigilancia son incorporados a redes interinstitucionales e interopera con redes de seguridad; sin embargo, han sido objeto de controversia por una potencial vulneración a la privacidad. Además, para su optimo funcionamiento, estas herramientas requieren la formulación de indicadores y construcción de bases de datos para generar información, que posteriormente será empleada para generar patrones delictivos.

“…The development of surveillance videos from closed-circuit television (CCTV) systems become popular around the world, in the last three decades. The crimes are also decreased with the help of surveillance systems [60]. Early detection of human abnormal behavior is very important to maintain security and quality of life, especially in places that are prone to crime [61].…”

Human Abnormal Behavior Detection is needed in several important sectors, especially in the field of public safety. Video Surveillance Systems are a trigger in detecting strange human behavior. However, this abnormal behavior data is rare and requires more costs to obtain, so the unsupervised learning method is used to study normal human behavior patterns only. There have been several previous studies that have provided significant results using this technique. There have been several previous survey studies related to human abnormal behavior detection, but they did not focus on unsupervised learning methods and the scope was too broad. In this paper, I present a survey regarding human abnormal behavior detection in more depth conceptually and classify it into two large parts, such as reconstruction-based detection and generative-based detection. This paper also offers a more extensive comparison with several popular datasets that are often used in previous research. Finally, I also shared several challenges and open research issues that emerged from our survey regarding future directions for future development.
