Recently, body-worn cameras (BWCs) have become a must-worn type of equipment for police officers to use in law enforcement. While the use of BWCs continues to increase, studies on the user experience of end users are still lacking. To understand how the multifaceted features are valued by the users (police officers) and identify the common dimensions behind these features, we conducted the present study by distributing a satisfaction questionnaire covering important features identified by a previous qualitative study. In total, 181 frontline police officers (Mage = 30.36, 86.7% are male) completed an online questionnaire in which they assessed their satisfaction with multiple features of BWCs, including waterproof, battery endurance, video quality, etc. Individual characteristics such as age, gender, working experience, and current position were also collected. Exploratory factor analysis revealed a three-factor structure: Adaptability, Portability, and Ease of use. We also found that all three factors significantly correlated with recommendation intention and overall satisfaction. These findings presented fresh and in-depth insights into how to design future BWCs. BWCs producers could increase technology satisfaction with police officer body-worn cameras by considering these factors and individual differences to enhance key features and provide personalized products and services.
