近年來，警察執法透由配戴微型攝影機進行證據蒐集及自我保護，但也同時涉及個人隱私權保障及裝備不足等情形，鑒於勤務執行與推廣重要性，警察配戴微型攝影機之認知與效能議題值得探究。本文透由問卷分析法，以新北市所轄分局警員為樣本，進行對於微型攝影機之認知及對其效能之實證探討。本研究發現，在使用微型攝影機認知、接受度、個人工作約束力、整體工作約束力及使用頻率上，勤務較繁重之分局員警在認知上較高；年齡、服務年資及對使用微型攝影機認知、接受度、個人工作約束力、整體工作約束力及使用頻率亦有顯著影響，但也突顯微型攝影機等機體效能可否跟得上勤務需求腳步之窘境。本文建議應強調對執勤配戴微型攝影機之保障認知，及對資淺警員提供相關之教育訓練，並購置功能及效能較佳之裝備供其使用，以增強員警執勤信心，提高依法行政之正向效果。

In recent years, the police have been wearing Body-Worn Cameras (BWCs) for evidence collection and self-protection in law enforcement, but it also involves the protection of personal privacy and insufficient equipment. This article uses the questionnaire analysis method to conduct an empirical study on the cognition and effectiveness of BWCs by adopting the police officers of the branch bureaus affiliated to New Taipei City as samples. The study found that, in terms of cognition, acceptance, individual work binding force, overall work binding force and frequency of use of BWCs, the police officers in the branch with heavy duty have a higher degree of cognition. Age, years of service, cognition and acceptance of using BWCs, individual work binding force, overall work binding force and frequency of use are also significant. But at the same time, it also highlights the dilemma of whether the performance of BWCs can keep up with the pace. Therefore, this article specifically suggests that the police should emphasize the protection cognition of BWCs on duty, provide relevant education and training for junior police officers, and purchase better equipment.
