Break-in detection system
First Claim
1. A break-in detection system for detecting intrusion into a surveillance area, the system comprising:
- an intrusion detection unit;
a monitoring system for monitoring the detected intrusion, the monitoring system comprising industrial television cameras maintained in coordination with said intrusion detection unit; and
an industrial television control system,wherein said intrusion detection unit comprises fibro-optic detection sensor means provided with fiber optic cables distributed in the surveillance area to work in coordination for detecting intrusion signals generated by means of external force exerted thereto, and as a transmission channel for said intrusion signals,said intrusion detection unit being capable of receiving said intrusion signals from said optical fiber cables, each fiber optic cable having first and second core wires arranged therein in parallel to each other for signal transmission,said intrusion detection unit being capable of enabling light pulses to enter said first core wire and be reflected in the form of said intrusion signals, andsaid second core wire being capable of transmitting televised image signals from the industrial television cameras and image control signals to and from the industrial television control system.

Abstract
A break-in detection system includes a detection sensor of an FBG type for detecting an intruder trying to climb over a fence around a premises, and a detection sensor of an OTDR type for detecting an intruder trying to demolish the fence. A fiber optic cable used as a detection sensor has a sensor core wire and a LAN transmission core wire arranged in parallel to form a LAN transmission channel. The LAN transmission core wire transmits videotaped image signals from ITV cameras and image control signals two ways between a monitoring room and an ITV control device. The LAN transmission channel is available for connection by IP telephone sets, a LAN terminal, a wireless LAN terminal, and an IP-BOX for internet communication. The system has excellent reliability and maintenance-free characteristics.
