闭路电视监控系统人身识别证据的质量是一个值得关注的课题。研究表明,熟悉面孔的识别和陌生面孔的识别都具有相当难度,比较而言,熟悉面孔的识别较为可信;反复观看录像资料能否提高对嫌疑人面孔的熟悉程度还需更多的实验;专家证据对于其他法庭证据是一种印证和加强,认为高清晰图像不一定要求专家意见来佐证的看法是错误的。 The quality of CCTV personal identification evidence is a topic of concern. Research shows that it is quite difficult to recognize familiar faces and to identify strange faces. In comparison, the recognition of familiar faces is more credible. More experiments are needed to see whether the repeated reading of video materials can increase the familiarity of the faces of suspects. Expert evidence is a corroboration and reinforcement of other forensic evidence, and the view that high-resolution images do not necessarily corroborate expert opinion is wrong.
