Abstract: Video Surveillance during night is important as far as security is concerned these days. The current technologies require RFIDs which are costly and hence the security domains in all become expensive. This paper describes the use of low cost single board computer Raspberry Pi which follows motion detection algorithm written in python as a default programming environment. It aims to present a review of various block matching algorithms used for night vision motion estimation. Developing a system which captures real time images and transmit it via a 3G Dongle to a Smart phone through e-mail. The algorithm for motion detection is being implemented on raspberry pi which enables live video streaming along with the human detection. The advantages and disadvantages of the algorithms are mentioned in this paper. The major goal of the paper is to provide a comprehensive reference source for the researchers involved in security.
