• Fence detection systems provide 360-degree coverage. Unlike cameras, which can only capture a limited field of view, fence alarm systems can detect intrusions from any direction. This means that potential intruders will have no blind spots to exploit, making it much more difficult for them to break into your property undetected.
• Fence sensor-based systems are more cost-effective. Cameras require a significant upfront investment in equipment and ongoing costs for maintenance (e.g. regular lens cleaning) and storage of recorded footage. On the other hand, Fence sensor-based systems are very cost effective to install and require minimal maintenance.
• Fence detection systems are more reliable. Cameras can be easily damaged or tampered with, compromising their effectiveness. On the other hand, Fence detection systems are designed to be highly durable and resistant to tampering. This means they are less likely to fail or be disabled by potential intruders.
• Fence sensors can better withstand harsh weather conditions, such as heavy rain, wind or extreme temperatures. This means that they are less likely to be damaged or become inoperable due to adverse weather conditions, whereas cameras may be more susceptible worse detection or to damage.
• Fence sensors are less obtrusive than cameras and can be installed directly onto a fence or underground. This means they are less visible to potential intruders and can provide a more discreet form of security.

Perimeter Fence Detection System &#; CHOOSE The right TECHNOLOGY For Perimeter Security

Choose the Right Perimeter Detection System for Your Business

Since there is common confusion about the different perimeter detection technologies, where they are used and the cost associated with each of them RBtec team thought it would be a great tool to clarify the differences and advantages and cases you should choose one or the other.

But let&#;s start first with the definition of what is a perimeter security system. By Wikipedia &#;A security alarm is a system designed to detect intrusion &#; unauthorized entry &#; into a building or other areas such as a home or school. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders.&#;

That means that our main goal when choosing a perimeter fence detection system is to remember the goal is to detect the intruder no matter what technology you chose! Now the next step is to understand what technology meets your needs, budget, and infrastructure.

The Different Technologies

Strain/vibration sensor cable mounted on a chain-link/welded mesh/barbed-wire fence.
Knowing if this is the right product for you is based on 3 categories:

• Length of your perimeter &#; Copper solutions fit mostly short to medium perimeters. In most cases, it will work best for fences up to 4km/ft/2.5 Miles.
  Where most cases are perimeters up to 600m/ft in commercial use.
• Budget &#; The copper sensor cable is the most economical way to transform your fence into a smart fence. This technology allows people who just want to add an alarm system to their fence in a simple, cost-effective, and user-friendly way.

Advantages

• 100% coverage of the perimeter no matter the shape, the cable is flexible. A great alternative to photoelectric beams / IR sensors at the same price level, easy to install. Unlike cameras that detect only if they can see the IRONCLAD will detect in any weather or lighting conditions.
• Dry contact relay output &#; simple to connect, simple to monitor with any standard alarm system or DVR.

Perimeter fence detection system vary in design but each is generally based on the detection of an intruder attempting to cut or climb over a fence. Depending on the version selected, it can be sensitive to different frequencies or levels of noise or vibration. The system is based on a coaxial sensor cable with the controller having the ability to differentiate between signals from the cable or fence being cut, an intruder climbing the fence, someone lifting the fence, or bad weather conditions.

The systems are designed to detect and analyze incoming electronic signals received from the sensor cable, and then to generate alarms from signals which exceed preset conditions. The systems have adjustable electronics to permit installers to change the sensitivity of the alarm detectors to suit specific environmental conditions. The tuning of the system is usually accomplished during the commissioning of the detection devices.

2. Infrared Sensors / Beams / Infrared Barrier

These are also called motion detectors, trip sensors, line-of-sight, or &#;laser&#; sensors. Though similar to the PIR motion sensors you may use inside your home or office, they&#;re designed for outdoors. Usually, there are two sensors aligned with one another to form a &#;gate&#; where If someone breaks the beam, the sensors trigger an alarm. Available in wire or wireless versions, sensors are typically installed inside the perimeter and require a clear path around the fence line to create a &#;no-go zone.&#; This means nothing can be parked or stored along the fence line.

Though this technology may sound like a great way to protect your facility it has drawbacks, the main issue is false alarms.
False alarms can be triggered when something disrupts the sensor &#;line of sight&#;. Since this sensor works similar to the human eye if the sensors can&#;t &#;see&#; they won&#;t be able to detect and trigger a false alarm. The false alarms can be caused when a physical object (vegetation, vehicles, dirt, animals, etc.) blocks the view or direct sunlight blinds the sensors. Even extreme temperature can affect detection distance and capability, as these are based on an infrared heat signature. Sensors also tend to require frequent maintenance. They&#;re usually cheaper in the short term but expensive in the long term since you need to add more and more layers to compensate for the false alarms.

3. Cameras and Video Analytics

HERE ARE FIVE REASONS WHY SECURITY CAMERAS ARE NOT ENOUGH:
1. Cameras are a forensic tool, in most cases, you will see the video AFTER the event already ended. It does not help you stop or prevent the break-in event.
2. Usually, cameras won&#;t cover 100% of the perimeter, in comparison to a fence alarm system you will always have blind spots where people can come in undetected.
3. Video analytics ability to detect is heavily relying on its ability to &#;see&#;, it&#;s a common mistake to think it will be able to monitor the perimeter 365/24/7. If weather conditions or objects (Vehicles, solar panels, containers) will block its line of sight the camera won&#;t able to detect an intrusion.
4. If you currently have no outdoor security the trespasser has an opportunity to plan their attack by surveying the area from the outside without being detected.
5. Indoor security does not protect the outside of your building, nor any items, property, or machinery left outside of the alarmed zone.
