Review of the e-JIKEI Network: Security camera system for privacy protection and community safety

Abstract

We review our proposed concept, the “e-JIKEI Network”, and relating social activities. Recently, security camera has attracted considerable attention for improving security in public places such as the station, shop, and street which is full of people's traffic. However, in the local community which is more important for individual person, installing of security camera makes little progress because of high installation cost and the problem of violation of privacy. To solve these problems and promote the installation of security camera, we established “The e-JIKEI Network Promotion Institute” (http://www.e-jikei.org/index_e.html) and developed two types of security camera systems. In order to reduce the installation cost, we developed computer-based security camera system named “Dairi-EYE” series and a stand-alone type security camera. The Dairi-EYE series can construct a security camera system with a computer and inexpensive cameras connected by using USB and LAN. The stand-alone type security camera can work with power-supply only and don't require wiring for video and network cables which raises the installation cost. To solve invading of privacy, we proposed privacy protection concept and introduced it into the Dairi-EYE and a stand-alone camera. A lot of social experiments using our security camera system have been carried out.
