Comparing different types of barriers for physical perimeter security

When it comes to securing your facility, selecting the right type of barrier is crucial. Barriers serve as the first line of defence against unauthorised access, vehicle ramming, and other security threats. At Westcoast Perimeter Security, we understand the importance of choosing the right barrier for your specific needs. In this article, we will compare different types of barriers to help you make an informed decision for your physical perimeter security.

Fencing
Fencing is one of the most common types of barriers used for perimeter security. It provides a clear boundary and can be tailored to various security levels.

Types of Fencing:
• Chain-link fences: Affordable and easy to install, chain-link fences are suitable for basic security needs. They can be enhanced with barbed wire or razor wire for added security.
• Palisade fences: Made of steel or iron, palisade fences offer higher security with their robust construction and intimidating appearance.
• Mesh fences: These fences provide a balance between visibility and security. They are often used in high-security areas where surveillance is crucial.

Pros:
• Cost-effective
• Easy to install and maintain
• Customisable security levels

Cons:
• May require additional security measures for high-risk areas
• Limited deterrence against determined intruders

Bollards
Bollards are short, sturdy posts designed to prevent vehicle access while allowing pedestrian movement. They are often used in conjunction with other barriers.

Types of Bollards:
• Fixed bollards: Permanent installations that provide continuous protection.
• Removable bollards: Can be removed or replaced as needed, offering flexibility.
• Automatic bollards: Mechanically operated to allow controlled vehicle access.

Pros:
• Effective against vehicle-based threats
• Minimal impact on pedestrian movement
• Versatile and customisable

Cons:
• Limited effectiveness against pedestrian intrusions
• Can be costly, especially automatic versions

Gates
Gates are essential for controlling access points in your perimeter security system. They come in various designs and functionalities.

Types of Gates:
• Swing gates: Open like a door, suitable for low to moderate traffic areas.
• Sliding gates: Slide horizontally, ideal for areas with limited space.
• Bi-folding gates: Fold in sections, providing quick access and space efficiency.

Pros:
• Controlled access to entry and exit points
• Can be integrated with access control systems
• High deterrence value

Cons:
• Requires space for operation
• Regular maintenance needed for mechanical parts

Road Blockers
Road blockers are heavy-duty barriers designed to stop or slow down vehicles. They are often used in high-security areas such as government buildings, airports, and military installations.

Types of road blockers:
• Rising kerbs: Hydraulic systems that raise a steel plate from the ground.
• Wedge barriers: Offer a larger blocking surface and are capable of stopping heavier vehicles.

Pros:
• High security and impact resistance
• Effective against high-speed vehicular attacks
• Can be integrated with other security systems

Cons:
• High installation and maintenance costs
• May require significant ground work for installation

Turnstiles
Turnstiles control pedestrian access, ensuring that only authorised individuals can enter a facility. They are commonly used in conjunction with access control systems.

Types of turnstiles:
• Tripod turnstiles: Common in low-security areas, allowing one person to pass at a time.
• Full-height turnstiles: Provide higher security by preventing individuals from jumping over or crawling under.
• Speedlanes: Designed for high-traffic areas, offering quick and secure access.

Pros:
• Effective control of pedestrian flow
• Can be integrated with access control and surveillance systems
• High deterrence for unauthorised access

Cons:
• Limited to pedestrian use
• Can cause bottlenecks in high-traffic areas

Choosing the right barrier for your perimeter security needs depends on various factors, including the level of threat, the type of facility, and the specific security requirements.
