Advantages of Fiber Optic Perimeter Security Monitoring and Alarm System

The fiber optic perimeter security monitoring and alarm system has significant advantages compared to other similar technologies:

Long measurement distance: The detection distance can reach 15km and the intrusion point can be accurately located.

Continuous distributed measurement: It can achieve simultaneous monitoring of multiple points and events without affecting each other.

High sensitivity and precision: The system parameters can be configured according to the environment, and standard communication optical cables can be directly used. The monitoring area is divided according to the site.

Rich pattern recognition: Backend pattern recognition accurately determines intrusion events through pattern analysis.

"0" missed alarm, extremely low false alarm: can be used in dangerous and harsh environments such as wind, rain, lightning, etc., with strong false alarm resistance. The system has undergone multiple rounds of high and low temperature, alternating humidity and heat environmental testing to confirm its adaptability to various harsh environments.

Flexibility: Adopting a positioning principle, the system has high spatial resolution; And the defense zone can be set arbitrarily through software without the need for reconstruction.

Excellent electromagnetic insulation, not affected by electromagnetic interference, essential lightning protection: The temperature sensing optical fiber used in the system is made of quartz, completely insulated, and not affected by lightning strikes; The frequency band of laser pulses transmitted in optical fibers is much higher than that of electromagnetic fields, and is completely unaffected by electromagnetic interference. Therefore, even working in a strong electromagnetic field environment is completely unaffected.

Intrinsic safety and reliability: The optical fiber used in the system does not generate any electrical sparks, and the average power of laser pulses transmitted in the optical fiber is very low. Even if the optical fiber is broken, there will be no danger.

Simple construction and easy maintenance: The armored optical fiber used in the system has excellent compressive and tensile strength, making construction easy and simple. It is difficult to encounter problems during use, and even if there is damage, it can be restored to work after being re fused by professional personnel.

High tolerance for additional losses: The system can tolerate an additional loss of 3dB, and can operate normally with 50% additional loss after removing attenuation loss.

Highly intelligent, easy to realize unattended: the system can send the report to the person in charge through SMS and the Internet when detecting abnormalities. Open design facilitates data management and on-site control.

High reliability and low cost: Unlike technologies such as video surveillance and electronic fences, detection fiber optic cables installed on the ground, underground, or walls have less obvious targets and are less likely to be maliciously damaged; And double-layer protective optical cables can be set up to distinguish the direction of intrusion. At the same time, if one layer of optical cables is maliciously damaged, the other layer can continue to conduct security detection, and double-layer protection does not significantly increase security costs.
