This paper addresses the problem of person re-identification and its application to real world scenarios. We introduce a retrieval tool that helps a human operator in browsing a video content. This tool is designed for determining whether a given person of interest has already appeared over a network of cameras. In contrast to most of state of the art approaches we do not focus on searching the best strategy for feature matching between pairs of cameras, but we explore techniques that can perform relatively well in a whole network of cameras. This work is devoted to analyze current state of the art algorithms and technologies which are currently available on the market. We examine whether current techniques may help a human operator in solving this challenging task. We evaluate our tool on the publicly available dataset and demonstrate practical advantages of the proposed solutions.
