די fiber optic vibration sensing perimeter security system can effectively detect illegal intrusion, suitable for any environmental, climatic, and geomorphic characteristics, and can reliably respond to various emergencies. Once an alarm occurs, the system can perform feature analysis on the intrusion signal, use environmental intelligent mode analysis to filter and shield false alarm signals, and transmit the alarm signal to the control center in the first time. It also links with cameras, broadcasting, lighting and other equipment on site to monitor and process the situation from multiple locations, thus establishing a comprehensive security guarantee system. The system is widely used in typical perimeter scenarios such as communities, prisons, airports, and railways. The response time of the video linked fiber optic vibration sensing perimeter security system is less than 15ms, with an accuracy rate of over 92% and a false alarm rate of less than 2%. It can achieve the goal of quickly and accurately judging and protecting against external intrusion and disturbance.

Traditional perimeter defense is no longer suitable for the security needs of critical departments, and installing advanced security technology prevention systems has become an inevitable measure. The perimeter alarm system is an important component of the security technology prevention system and the first line of defense for the security alarm system. In some important areas, such as communities, prisons, airports, railways, אאז"ו ו, perimeter security systems can be built to prevent illegal intrusion and various destructive activities, ensuring the safety of people’s lives and property. Traditional perimeter security systems that use technologies such as infrared radiation, laser radiation, pulse electronic fences, tension electronic fences, and leaky cables have high costs, ranging from four to five hundred thousand yuan to millions of yuan. אָבער, the use of vibration sensing optical fibers linked to monitoring videos can achieve higher security and meet the needs of various application scenarios at a lower price.

Installation and laying method of distributed fiber optic perimeter security sensing and monitoring system:

1. Prevent unauthorized access

wire mesh

Linear laying: A single sensing optical cable is fixed in a horizontal straight line on the railway grid, which can detect intrusion methods such as climbing and crossing, and is suitable for occasions with low security requirements.

Parallel line laying: Multiple sensing optical cables are horizontally fixed on the iron grid to increase the detection and sensing area, enhance the sensitivity of intrusion signal detection, and detect intrusion methods such as climbing, climbing over, and cutting nets. It is suitable for occasions with high security requirements.

Metal fence

Due to the hard texture of the metal fence, in order to reduce false alarms, it is necessary to increase the number of sensor optical cables laid to ensure detection sensitivity, such as laying one sensor optical cable at the top, middle, and bottom of the fence. When security requirements are high, the perimeter can be increased

The number of sensing optical cables laid in the middle of the column.

Circular iron network

The circular iron network is usually located at the top of the fence and has a lightweight and scattered structure, which is susceptible to environmental disturbances and false alarms. דעריבער, sensing optical cables should be laid on both sides of the fence near the bottom of the iron network. Due to the inability of this laying method to prevent wall excavation intrusion

It is best to use it in conjunction with other laying methods.

2. Prevent wall intrusion by chiseling

Lay multiple sensing optical cables in parallel on the wall to detect the vibration alarm generated during wall chiseling. To reduce false negatives, the number of sensing optical cables should be increased according to the height of the fence, and the optical cables should be fixed at equal intervals on the wall.

3. Underground anti crossing intrusion

The buried laying of sensing optical cables is relatively concealed and not easily detected by intruders in advance. Determine the laying depth based on the ground conditions (such as grassland, sand, אאז"ו ו), lay the sensing optical cable in an S-shaped or parallel manner with multiple sensing optical cables, and then re cover it. When an intruder enters the defense zone or the vibration generated by underground excavation is detected, an alarm will be triggered. The embedded fiber optic grating perimeter system can detect various vibrations around it, and through linked video surveillance, it can distinguish various intrusion behaviors. פֿאַר בייַשפּיל, when someone passes within 3 meters of the vibrating optical cable, the system can detect abnormal signals and retrieve monitoring information of the intrusion location to determine whether it is an intrusion behavior.
