This paper meta-analyze from image and cognitive psychological point of view the preceding researches on the effects of CCTV on criminal identification, which have been made by the British criminalists and cognitive psychologists since 1990s. By doing so, I aim to reveal the powers and the limits of CCTV for human identification. The conclusion is summarized as follows. First of all, there are many limits of CCTV for the human identification from a image point of view. First, CCTV images give an operator too massive and boring visual information at the same time. Second, it is difficult to compare and identify the CCTV images, because they are not standardized. Third, it is hard to extract a full face photo of a criminal from CCTV images. Fourth, it is difficult to identify exactly the human face of which characteristics vary continuously among individuals. In addition, from cognitive psychological point of view, the effect of CCTV for human identification depends on the observer’s prior knowledge of the observed. It is revealed that the observer cannot identify strangers easily from very high quality CCTV image. On the contrary, the observer can identify the observed known, even from the very poor quality CCTV image. This is where the significance of CCTV for human identification is most obvious.
