Abstract
The purpose of this study is to verify the practical effectiveness and sustainability of accident prevention through the introduction of video monitoring systems, such as intelligent CCTV and body cams attached to signalers/workers, in construction sites. In particular, this study aims to investigate whether the introduction of such technology increases workers' compliance with safety regulations and how this effect changes over time specifically, the occurrence and dissipation of the 'Hawthorne Effect'. Existing literature and data analysis indicate that while the introduction of smart safety equipment (CCTV, AI integration, etc.) significantly reduced site disaster rates (e.g., an average reduction of approximately 23%), the behavioral change effect induced by monitoring tended to decrease after a specific period (e.g., about 8 weeks). Furthermore, it was confirmed that if the monitoring system is combined with a 'punitive culture,' it can lead to adverse effects such as a decrease in 'near-miss' reporting and the concealment of hazardous behaviors. Therefore, this study, focusing on actual cases, utilizes pre- and post-indicators to suggest that monitoring systems can achieve sustainable and positive accident prevention effects only when utilized as tools for 'data analysis' and 'real-time feedback' beyond simple 'surveillance and control'.
