Fiber Optic Sensor Physical Security Systems Distributed

What are fiber-optic intrusion sensor systems?

For critical sites such as airports, seaports, power plants, government buildings, and power generation plants, physical security is a priority. Perimeter systems are the first line of defense against intruders. As the name suggests, fiber optic sensor physical security systems alert security personnel if a perimeter line is breached by a suspected intruder. Although pressure-sensitive materials are an intelligent approach to perimeter security, motion detection is much more affordable and requires less maintenance in the long run—especially for outdoor applications where they may be exposed to the elements.

What is a Fiber-Optic Security System?

Images

Fiber optic systems allow security images from cameras to be transmitted exceptionally quickly and reliably. The inside of a fiber optic cable contains strands of glass the width of a human hair, and the digital image is transferred as light ...
... to a receiver on the other end.

Optical detection/intrusion alarms

When sensors are used in conjunction with FBG interrogators it is possible to trigger an alarm if the continuity of the stream of light is interrupted. This is a military-grade technology that is now available to the public at increasingly affordable rates.

What are the Benefits of a Fiber-Optic Security System?

Although physical barriers such as fences remain an effective and visible deterrent, fiber optic security systems reinforce the efficacy of those physical barriers by providing an optical deterrent, especially when paired with other strategies such as human patrols and camera monitoring.

Fiber optic security systems decrease false alarms when compared to other types of security alarms. More concerning are false negatives, which lead to possible threats and an overall distrust of the security system. Fiber optic cables can be buried, mounted on fences, run through walls, or fabricated into concrete, and they are a sturdy and reliable technology. Some manufacturers state that their fiber optic cable will not need to be serviced for up to 20 years.

FGB interrogators, which receive data from fiber optic sensors, are built to be exceedingly rugged and reliable, and able to withstand harsh environs such as marine applications, airport runways, and amongst vegetation.

Fiber optic cables are simple to diagnose, and in the event of a break it is possible to estimate where the break happened—something typically not possible with standard data and electrical cables. They are immune to electrical interference and have a longer distance capability than traditional coaxial cable. Fiber optic cables can also carry data two ways, enabling camera operators’ instructions to tilt and zoom on a camera to travel down the same cable as the image.

Unlike copper-based systems, fiber optic security systems are impossible to detect and therefore extremely difficult to disable or bypass. It is simple to install and there are many contractors who specialize in the installation of fiber optic cable.
