Vibration fiber optic intrusion alarm system host, fiber optic vibration monitoring, fiber optic vibration measurement, fiber optic vibrator, fiber optic vibration monitoring technology, vibration fiber optic perimeter alarm
FJINO provides a distributed fiber optic vibration monitoring system, which uses sensing optical cables as sensing units to monitor various vibration signals directly touched or transmitted to the vibrating optical fibers through carriers such as soil cover, wire mesh, fences, walls, etc. in real-time and continuously. Vibration fiber optic supports multi scenario installation, such as wall embedding, wall hanging, network hanging, buried and other common scenarios. Due to its passive front-end, it is very suitable for flammable and explosive places, as well as projects with long perimeters such as airports.
Principle of Fiber Optic Vibration
（1） Alarm handling
In the security area, when climbing or intrusion occurs, sensors can accurately detect signals and transmit them to the processor. After processing and analysis by the processor, an alarm signal is issued.
When an alarm is triggered, the alarm record is displayed in real time, including the alarm zone. The location of the alarm zone, the start time of the alarm, the number of alarm events, and the note information are displayed in real-time on the map in a record table.
2. The system can adjust multiple sensitivities such as amplitude, frequency, and phase of the detection system at will, filter out some small disturbance signals, and eliminate false alarms caused by environmental factors such as passing pedestrians, vehicle noise, tree branch swaying, and weather changes. This ensures that the entire security system has a high detection probability while having an extremely low false alarm rate.
（2） Global electronic map
Display the distribution of defense zones and alarm points on an electronic map, and can be expanded to selectively display multiple defense zone maps with audio and video assistance.
（3） System monitoring
The waveform curves of monitoring points are published in graphical form, displaying real-time waveform signal graphics of designated sensors in designated defense zones, enabling staff to timely grasp real-time information and relevant historical data on the operation status of each defense zone.
（4） System management
1. Initial setting: After the initial parameter setting of the system is completed, the system can automatically detect the parameter information saved in the last setting during future use, without the need to set it again.
2. Multi level permission user management: It can facilitate the addition, deletion, modification, and browsing of users
Basic information, including account, password, permissions, etc.
3. User login log: When a user logs into the system, the login user information is automatically recorded;
4. Database backup.
（5） Alarm linkage
The defense zone alarm can send alarm protocol data to other devices and software systems through the network or interface. It can freely configure video surveillance linkage, control GSM, on-site recording, lighting broadcasting and other alarm linkage systems. When the fiber optic vibration defense zone generates an alarm, the system can link one-to-one, one to many or many to one video surveillance, sound and light alarm, and related centralized monitoring platforms.
（6） Protection performance against damage
In the normal operation of the distributed fiber optic perimeter alarm system, when someone damages the optical cable, the system will sound an alarm. The system has a complete structure, and each area is complete and independently adjustable, without affecting the monitoring of other defense zones due to disturbances or cuts in one area.
（7） Restoration of alert status
After the activity that caused the alarm state stops,
This system restores the alert state by clicking on the alarm reset button.
（8） The laying method is flexible and versatile, and can be mixed for laying
The sensing optical cable of this system can be directly laid on the surface of fences and walls, buried in walls, or laid below the ground (under grass or sand). It can also be installed underwater without the risk of electric leakage, lightning protection, and stable and reliable performance.
Product features:
Strong anti-interference: The vibration sensing optical cable adopts passive detection principle, which can eliminate the interference of external strong electric and magnetic fields, effectively avoiding equipment damage caused by lightning, and has high system reliability.
High sensitivity: The detection sensitivity of the host can be adjusted in multiple levels to adapt to various complex environments.
Convenient construction: Installation and disassembly are very convenient, plug and play. Effectively reduce installation costs.
High stability: The optical cable has low loss and high stability during transmission, with a maximum detection distance of 500m per defense zone.
Passive detection: The vibration sensing optical cable is a passive detector that is non-conductive and can effectively avoid lightning strikes. It is suitable for flammable and explosive places.
Installation method: The vibrating optical cable can be directly laid on various iron nets to prevent climbing.
Output signal: The standard switch signal can be connected to a universal anti-theft alarm controller.
Multi channel acquisition: The dual channel data collector can collect defense zones from two different media.
