Abstract: A multi-point security system employing network communication is provided. The system includes a main unit (10) being connected to a digital server (50), a video and audio recording unit (20) and a sensor and alarm unit (30), wherein the video and audio recording unit (20) and the sensor and alarm unit (30) are formed by a plurality of monitoring devices (21) and sensors (31), which simultaneously collect scanning data and feed the data back to the main unit (10) by wireless means. Multiple monitoring points can be set up in strategic locations for close surveillance of the site situation around-the-clock, and the scanning data can be accessed through a personal computer (60) or cellular phone (61) with a predetermined network or email address.
