The OFS system is a centralized high-end perimeter intrusion detection system
based on a defense area localization mode. It uses advance optical fiber
vibration sensing technology and is highly sensitive to any third party’s
intrusion. By using advanced optical and electric signals processing technology
and intelligent mode identification technology, the OFS minimizes any false
alarms resulting from various environment noises such as wind, rain, snow,
passing vehicles, cats, gods and other small animals. The signal processing
terminal and the central processing unit are shown in the right figure.
