Everything You Need To Know To Find The Best RF970 Fiber Optic Perimeter Intrusion Detection Systems

Fiber optic security detection systems are quickly becoming the market standard for perimeter security. These systems use fiber optic fence sensors to detect any intrusion, providing immediate alerts to the security personnel. Such a system is not only effective in detecting intrusion but is also cost-effective since it requires minimal maintenance. One of the key benefits of a fiber optic security detection system is that it provides high-quality video footage of the intrusion. This feature is especially important in cases where the perpetrator needs to be identified, and it provides visual evidence for legal purposes. Additionally, the system has a high degree of accuracy, reducing the incidence of false alarms. Fiber optic perimeter security systems are ideal for government agencies, prisons, and military installations, but they are equally suitable for commercial and residential properties. They are easy to install and require minimal infrastructure, making them a popular choice for those with limited budgets. One example of the effectiveness of a fiber optic security detection system is in Sierra Leone, where the system is used to secure key government installations. In Fiji, the security system is used to protect coral reefs from illegal fishing and harvesting, while in Iran, it’s used to monitor sensitive military installations. East Timor has also implemented fiber optic fence sensors, particularly at border crossings and checkpoints. In Slovenia, the system is used to protect national parks and wildlife reserves. Fiber optic security detection systems provide a comprehensive solution to all perimeter security issues. They are durable, weather-resistant, and can be customized to meet the unique needs of each property. With the increasing need for perimeter security, such systems are becoming more of a necessity than a luxury.

Fiber Optics Used in Intrusion Detection

3/27/

Many of us have fiber optic cable that delivers Internet access to our homes or offices. But optical fiber cable can be used for more than high-speed data transfer. I'm not talking about artwork or illumination but a vital security application: physical intrusion detection.

To understand how this works, you need to know a little bit about fiber optic cable. There are two types of fiber: single-mode and multimode. Without getting deep into the weeds and mathematics of the transmission of light in the two types of fibers, there are some crucial differences:

Single-mode fiber can be used in applications requiring higher speeds or longer distances.

Single-mode fiber has a minimal diameter compared to multimode.

Single-mode fiber is more expensive per meter, and the equipment is more expensive than that for multimode.

Single-mode and multimode fiber can each be used for intrusion detection, but the mechanisms are significantly different. Vendors who sell intrusion detection schemes based on fiber keep their exact schemes proprietary, but the concepts are similar. For example, one factor the vendors keep confidential is determining whether the intrusion was by a pedestrian or a vehicle.

How it works

In the case of multimode fiber, the concept is straightforward: a laser sends light through the fiber (as when the fiber is used to transmit data). The light at the receiving end forms a speckle pattern when the fiber is undisturbed. When the fiber is under pressure or significantly bent, the pattern of the light at the receiving end changes. This allows a device at the receiving end to analyze the distortion and notify a monitoring device accordingly.

In the case of single-mode fiber, things get a bit more complicated. The nature of light traveling in a single path or mode through the fiber, no pattern at the receiving end can be disturbed. Instead, one wavelength or color of light is sent through the fiber in one direction, and another wavelength of light is sent in the other direction. Pressure on the cable changes the way the cable transmits light that can be detected at the end of the cable.

(Another technique involving light pulses has been used to detect earthquakes, which is beyond the scope of security uses.)

When might it be used?

Using fiber optic cable for intrusion detection is not inexpensive, so when might it be appropriate? Significant applications are in areas where a clear view of a perimeter or internal area cannot be easily viewed directly.

Consider a facility where one or more portions of a perimeter border an area of dense vegetation such as a forest. In that case, the physical plant may want to erect a fence on that perimeter. A cable could be integrated with the fence or placed inside or outside it to detect vehicles or individuals at the fence or trying to cross it.

Inside a facility, a system might be deployed where there is little activity at a particular time of day. Specifically, a system might be used in a server room not generally occupied at night.

Rightly, organizations are often reluctant to discuss their specific security measures. That makes knowing how many and what types of fiber optic intrusion detection systems are in use. But a web search for vendors indicates that the market size is not trivial. Who knows, you or I may traverse such a system daily. But, if you do - knowingly or unknowingly - at least you know how it works.

In the last couple of years, the use of buried sensor for perimeter intrusion detection system, becomes very popular due to the advantage of been a discreet or even an invisible detection system and avoiding the need to build an above-the-ground fence to protect the perimeter due to costs or environmental reasons.

Buried Perimeter Intrusion Detection Systems are used to protect (among others)

Borders

Oil & gas pipelines and facilities

Military bases and other land facilities

Airports and seaports

Prisons

Farms

Airports

Underground Intrusion Detection Systems Advantages

Invisible system, the intruders can’t see the underground intrusion detection system

No need to build anything above ground level

No need for line of sight as required by some security products such as radars, Microwave, IR and video systems.

Three types of Buried Perimeter Intrusion Detection Systems

There are several systems based on different technologies for creating buried intrusion detection system.

Seismic sensors system– seismic sensors are buried underground and by recognizing vibrations in ground, they detect and locate intrusions. In this article we focused on invisiFence by SensoGuard as the ultimate seismic sensors system.

Leaky coax system –the buried leaky coax cable creates an electromagnetic volumetric detection field. The controllers monitor this field to detect and locate variation caused by intrusion.

Fiber Optic system– central controller transmits pulses of signal and analyzes the reflections and disturbances to detect and locate intrusions.

We will focus on the following subjects when comparing the three: performance, installation requirements, limitations and costs.

Systems Topology Description

SensoGuard Seismic Buried Perimeter System (InvisiFence) composed of seismic sensors strings connected to a local processing unit every 50m and a central hub unit every m.

Fiber optic systems- composed of a central controller which can analyze a very long fiber optic cable (up to 80km).

Leaky coax system- composed of leaky coax cables connected to a local controller every 400m (for single cable).

Buried Perimeter Intrusion Detection Systems Installation Considerations and Limitations

All buried systems require digging a trench for placing sensors/cable. However, limitations regarding installation environment and installation depth are different from one system to another.

Seismic Buried Perimeter System (SensoGuard’s InvisiFence)
The trench depth is 30-50cm (precise depth is not an issue, can be anywhere between 30cm and 3m)

Fiber Optic system
Installation depth accuracy is a critical (no more than 20cm)
If installed deeper (30cm for example) the system performance will be greatly reduced.
Shallow installation increases the possibility that cable will be exposed over time (due to environmental elements such as wind) or the detection performance will be poorer overtime if additional soil or vegetation will be added or grown above ca

Leaky Coax cable

Installation depth accuracy is critical. The system’s performance will be compromised if the cable is placed deeper than recommended (23cm for example). Shallow installation increases the possibility that cable will be exposed over time.

System cannot be placed near metal objects – such as metal fences or metal pipes.

Water / snow above the system will cause false alarms. The RF signal cannot bypass water/snow, resulting in poor system performance and false alarms in case of puddles or snow on the ground.

Maintenance after Installation

Among the 3 technologies, the fiber optic system is the most complex system to repair in case of fault. Fiber optic cable replacement is a very sensitive process and there is always the chance of additional mechanical damage during the repair.

Leaky coax systems are easier to repair than optic fiber systems but harder to repair compared to SensoGuard’s InvisiFence. Not always easy to find the faulty point and required to keep the installation requirement and drainage.

All of SensoGuard invisiFence components are replaceable easily and quickly.

Leaky coax systems require periodical calibration due to changing condition of soil above the system. The changing conditions will affect the system sensitivity and false alarm rate. In contrast, SensoGuard buried perimeter system doesn’t require periodic calibration after installation.

System Costs

For projects of several km – SensoGuard buried perimeter system and leaky coax are cheaper than fiber optic system.

For projects above dozens of km – fiber optic system is the cheapest option.

InvisiFence is cheaper for projects of less than 2km.

Performance & False Alarms

All three perimeter security systems: SensoGaurd’s Invisifence, the leaky coax system and fiber optic cable system are buried systems that detect above the ground movement. However, Invisifence does stand out as the most reliable one for three reasons. The first, the actual depth of Invisifence can be anywhere between 30cm-3m without any decrease in the system’s performance. That means that you can bury the system deeper or in case soil will be added (in desert, or after a storm), the system will continue to function without any problems.

In contrast, Leaky coax and fiber optics systems are very much affected by depth. If you bury them too close to the ground or deeper than advised, their performance will be greatly compromised. Secondly, InvisiFence is less affected by environmental changes. While Leaky Coax and fiber optic systems may set off false alarms in case of puddles or growing vegetation, InvisiFence seismic system will by far more reliable and will not set off false alarms in such cases.

Lastly, InvisiFence has smart adaptive deep-learning algorithm. By using the algorithm, the system constantly learns and adjusts to its environment. The system constantly sets a new signature of what is the “normal” state of things in order to detect intrusions and avoid false alarms. Based on environmental changes such as new road or vegetation, the normal state signature is always revised. InvisiFence is the only system which makes the needed adjustments to detect threats without the need of making any external changes.

Perimeter Intrusion Detection: Comparison between 3 Systems Seismic, Fiber Optic and Leaky Coax

Summary: Which Underground Perimeter Intrusion Detection System is preferred?

In one sentence, SensoGuard seismic InvisiFence system is the best choice of the three technologies.

Let’s look at it with more details. Fiber optic systems are more expansive and less reliable than Leaky Coax or seismic systems. So the choice is really between Leaky Coax systems and InvisiFence seismic system.

InvisiFence is far more reliable in terms of threat detection and avoiding false alarms. It is also easier to install which makes it superior to Leaky Coax systems.

As for costs, for securing perimeter of several km, InvisiFence is cheaper than both Leaky Coax systems and fiber optic systems. However, in perimeters of above 10km, Fiber optics systems are cheaper.

SensoGuard’s  InvisiFence is the best cost effective underground perimeter intrusion detection system in the market today. You can read more about it in SensoGuard perimeter security systems  page.
