3 Common Perimeter Security Mistakes

With the intent of preventing intrusion and keeping your facility safe from all angles, perimeter security is a vital part of any physical security plan. It comes in a variety of forms from cameras to fences to ground sensors, all of which can play an important role in protecting your facility from unwanted outsiders. Unfortunately though, it’s not uncommon for security personnel to ineffectively employ perimeter security measures.

In today’s article, we’ll discuss three common perimeter security mistakes normally associated with ground sensor emplacement and how you can overcome them to improve your facility’s current security setup.

Mistake Number One: Linear Security Placement

First, I would like to clarify that linear security placement is not always a “mistake.” It can be a viable, successful way to keep your facilities secure by creating an invisible fence around your facility like the picture below. This is a commonly used tactic and is great for identifying when something or someone is entering your property, but it can also have a few drawbacks.

The first of which is that linear placement offers little information about who or what is trying to enter your property as well as their intent once they have entered your grounds. Using daisy chain placement only informs you that something or someone has crossed the threshold of your perimeter. After that, you have little to no information about where they have come from or where they plan to go.

Not to mention, often because of costs, linear emplacements are employed right along the defended area, resulting in security personnel only being alerted once the intruder has successfully crossed onto your site. In these situations, the intruder may be able to damage your facility before your staff has time to intercept the threat.

Another issue with linear placement is its tendency to cost more money than needed by securing the whole space but not necessarily the right space. Virtual fencing requires sensor placement around an entire facility, which means you’ll have to purchase more sensors than if you were to adopt a strategic placement approach. And, if you want to ensure personnel have enough time to react after receiving an alert, you must push your linear fence out even further from your facility, requiring even more sensors. With commercial sensors ranging in price from $500 to more than $3,500 a piece, the cost of linear perimeter security can quickly spiral out of control.

Our Solution: We recommend strategic security placement in addition to, or in lieu of, linear security placement. By placing your security measures in strategic points of penetration, such as bridges, gates, fence lines, and rail lines, you’re able to secure the most probable entry points, without having to blow your budget to secure your space. Placement beyond your perimeter will also notify personnel of any suspicious movement near the facility, giving them a chance to monitor and intercept the threat before its able to cause any harm.

Mistake Number Two: The Reactive Approach

Security personnel often take a reactive, instead of a proactive, approach to perimeter security, in which they wait for an alarm to sound and then act without monitoring the situation. Like linear placement, a reactive approach to security also limits your staff’s ability to analyze and intercept the threat before they’re able to cause destruction.

Our Solution: We recommend a proactive approach called threat pattern analysis that allows you to understand normal behaviors within and around your facility’s grounds. You can do this by strategically placing unattended ground sensors outside of your perimeter, which will help you to identify and understand regularly-occurring behavior patterns as well as those that are out of the ordinary.

Once you are able to create a baseline of normal behavior over a period of weeks or months, you can compare your findings to data from previous threatening situations, allowing you to identify anomalies. After this process is complete, you can push your sensors out even further beyond your perimeter to gain insight into how threats are conducting surveillance.

The purpose in collecting the data is to provide security personnel with a more in-depth understanding of how future threats will surveil and approach your facility. These insights will enable them to monitor and identify threats quicker in the future.

Knowing movement patterns will also help you to choose when and where you’ll be able to intercept the threat, creating the perception of a “chance encounter” without disclosing your ground sensor strategy and capability.

Mistake Number Three: Only Employing Visible Security Measures

Many companies employ visible security measures, such as  cameras and fences, as a way to deter intruders. While we support the use of these security measures, attacks or physical penetrations are almost always preceded by some level of surveillance or reconnaissance. In other words, visible security placement enables intruders to study your security setup and devise a plan to avoid or destroy equipment long before an attack.

Our Solution: Covert ground sensors are a great alternative, or partner, to visible security measures. Ground sensors are designed to sit just below the surface, making them a covert security measure that will likely go unnoticed by threats surveilling the area.

For further protection, ground sensors can be placed asymmetrically around your facility, making it even harder for intruders to understand your security layout. As we mentioned earlier, linear placement may allow intruders to predict the placement of your security, allowing them to devise a plan to avoid or damage them. With a sporadic, yet strategic, placement plan, ground sensors can allow you to secretly monitor, analyze, and intercept your threat to keep your facility untouched.

Overcoming the Issues

The best way to overcome weaknesses in your security plan is to implement an integrated security setup that diversifies your security measures to overcome the vulnerabilities of various security plans. 

Pathfinder works well with security cameras and fences to give a well-rounded security solution that will help you to overcome weaknesses in your current security setup. With the ability to send alerts to your cell phone when movement is detected, Pathfinder provides a stealthy alternative to traditional perimeter security.
