非成套窃照专用器材检验方法研究

Perception into Verification of Function-deficient Illegal Furtive-photographing Special Equipment

非成套窃照专用器材由于存在结构或功能上的损坏或缺失,无法直接采用成套窃照专用器材的检验方法进行检验,因而成为窃照专用器材检验工作的难点。本文首先对窃照专用器材进行了分类,定义了非成套窃照专用器材,然后从照相、摄像器材的结构和功能定义的角度对非成套窃照专用器材的完整性进行了分析,认定检材只有满足功能完整的条件才能进行进一步检验。最后在非成套窃照专用器材的完整性分析的基础上介绍了非成套窃照专用器材的检验方法,并结合一个实际检验案例进行了分析。本文介绍的非成套窃照专用器材检验方法,将为此类型窃照专用器材的检验提供有效的途径和思路,从而推动窃照专用器材检验业务的发展。

The function-deficient illegal furtive-photographing special equipment is difficult to verify directly with the methods that are eligible for those function-complete ones because of its structural or functional damage or fault,hence making it a handicap for the examination of illegal furtive-photographing special equipment.Through classifying the illegal furtive-photographing special equipment at the beginning,this paper defined the function-deficient illegal furtivephotographing special equipment,with the analysis into the integrity of function-deficient illegal furtive-photographing special equipment from the definition of structure and function of camera and photo-taking device,concluding that none of evidential materials can be examined further but the complete functional requirements being met.Finally,the verifying method of function-deficient illegal furtive-photographing special equipment was introduced from the analysis of functional completeness,demonstrating into an actual case.The here-elucidated method to verify the function-deficient illegal furtivephotographing special equipment,will provide effective choices and reference for examination of illegal furtive-photographing special equipment,thus capable of promoting the development of such forensic service.
