Introduction: Preparation is Eeverything

It takes more than a tall fence topped with barbed wire to properly protect a perimeter. A well-secured perimeter consists of multiple defense layers, reinforced by robust security solutions. To ensure these layers complement each other effectively, you need a solid plan.

More than ever, businesses realize the importance of stopping criminals before they can damage property or harm customers or employees. According to IFSEC Global, referencing Research and Markets (a leading market research company), the global perimeter security market was valued at around €17.4 billion in 2020 — and it continues to grow.

Yet a fundamental problem remains: many organizations still struggle to develop and implement a comprehensive perimeter security plan. That’s why it’s crucial to work with experienced, certified installers. At the same time, having a basic understanding of key considerations will help you actively contribute to the planning process.

To assist you, we've summarized the six most important questions to ask when designing your perimeter security blueprint:

‍

1. How do you define "perimeter"?

A perimeter refers to the boundaries that outline or protect an area. Perimeter security involves securing vulnerable locations or structures within those boundaries.

When developing a perimeter security plan, one of the first things to consider is the size of the perimeter. Typically, longer perimeters require more fencing and additional security solutions. The shape also matters: perimeters with many curves and corners can challenge certain security technologies (more details in our Ultimate Outdoor Detection Guide).

While each site has its specifics, a few constants remain. Think about:

• Identifying all entry and exit points: These are typically the easiest areas for intruders to breach.
• Evaluating the physical perimeter: This can include walls, fences, natural vegetation, or other barriers.
• Understanding the consequences of a breach: Should an alarm trigger as soon as a fence is crossed? Or is the direction and distance of the movement more important?

It's critical to view the site's layout as concentric circles, with the innermost area being the most critical — like an onion, where each layer represents a line of defense.

2. Is the technology we want to use up to date?

Using the latest technology is essential for several reasons:

• Regulatory compliance: Especially for healthcare facilities or businesses working with federal agencies. For example, in Belgium, the law of April 7, 2019, requires healthcare sites to regularly update their security solutions to protect against (digital) breaches.
• Improved product efficiency: Video motion detection technology has evolved from pixel-based to object-based detection, capable of identifying objects based on size and speed. Thanks to innovations like Edge AI, processing can now happen directly on devices, improving efficiency and reducing false alarms.

Edge AI systems (like Secury360’s solution) not only minimize false alerts but also isolate failures: if one device malfunctions, it doesn't bring down the entire system — unlike centralized solutions.

• Cyberattack protection: IoT technology, such as IP cameras, is inherently connected to networks and vulnerable to cyber threats. Deloitte reports that Distributed Denial-of-Service (DDoS) attacks are increasing in frequency and scale. Keeping solutions updated is vital. Advanced systems like Secury360 also allow remote updates to ensure your security is always current.

When evaluating updates, consider whether detection methods like fence loops, passive infrared, radar, dual-sensor technologies, thermal cameras, loudspeakers, and lighting integrate seamlessly into your overall security plan.

3. Will climate or environmental conditions affect detection?

Environmental factors will always influence detection accuracy. Some examples:

• Lighting: Cameras pointed at sunrise or sunset may struggle without wide dynamic range (WDR) or thermal technology.
• Wind: Strong winds can cause camera shake. Electronic Image Stabilization (EIS) helps reduce this.
• Humidity: Moisture inside camera lenses can blur images and damage electronics. Premium cameras often feature internal fans or fast-drying technology.
• Corrosive Environments: Coastal locations and chemical-heavy facilities require corrosion-resistant cameras, often made from stainless steel or polycarbonate.
• Extreme Temperatures: Icy conditions can freeze components. Without proper technology, a camera might fail to start or operate correctly.
• Mounting Surfaces: Cameras mounted on porous or thermally unstable surfaces can experience condensation and should be carefully considered during installation.

4. Who receives the alert when detection occurs, and how?

Modern IP detection technologies allow for remote perimeter monitoring. Security teams can observe from control rooms, patrol facilities, or monitor sites via mobile devices. The Secury360 app (available for iOS and Android) lets customers decide who receives alerts: security staff, owners, or both.

Effective perimeter solutions only alert when a real threat is detected. Reducing false alarms is crucial, as excessive false notifications can overwhelm personnel and lead to costly mistakes.

Secury360 stands apart by combining location-trained AI with certified local alarm centers for a second verification layer, offering:

• Lower costs from fewer false alarms: False alarms can lead to fines or legal action if police respond unnecessarily.
• Reduced material damage and losses: Quick reactions to intrusions prevent costly incidents.
• Reduced emotional impact: Invasions damage trust, and businesses operating warehousing or logistics operations could lose customers if seen as "poorly secured."
• Minimized business interruptions: Especially critical for sensitive sectors like healthcare, government, and pharmaceuticals.

5. How can I identify what caused the alert?

The right perimeter solution makes it much easier to understand what triggered an alert.

For example, thermal cameras with intelligent analytics produce fewer false alarms and are less affected by rain, snow, or fog. Some also feature EIS to remain stable in windy conditions.

In poor lighting, Wide Dynamic Range (WDR) or 950nm infrared cameras can reveal hidden threats. Although IR doesn’t capture natural color, it enables stealthy surveillance. However, keep in mind:

• IR is less effective in rain, where droplets distort reflections.
• IR works better in cluttered environments rather than on plain surfaces.
• Low-wavelength IR emits a faint red glow detectable by criminals.

In some cases, adding external lighting might be necessary to ensure proper object identification — though this can increase long-term costs.

6. What level of detection do I need?

A key goal should be eliminating blind spots along the perimeter. Ask yourself: Is it equally important to detect a threat at 5 meters and 500 meters?

If yes, don’t just rely on product specs — evaluate the real-world application. Even the best product can fail if poorly installed.

For example, a thermal camera rated for 500 meters is great — but if you need to distinguish between a human and an animal, it might not be sufficient without proper settings or additional technologies.
