Abstract

A portable surveillance camera and a personal surveillance system are disclosed. More specifically, provided are a portable surveillance camera comprising a mini-camera such as a CMOS camera or a CCD camera, and a system for surveilling a predetermined place using the portable surveillance camera. The personal surveillance system receives multimedia data such as image, sound, event and control data on real time from the portable surveillance camera installed in various areas such as a house, a shop or an office with a control device connectable to a network such as a LAN or an internet, and then monitors or stores the multimedia data. Also, the personal surveillance system can search, surveille, control, edit and store multimedia data such as image, sound, event and control data for a desired period of time from data stored in the portable surveillance camera or the control device.
