Indoor and Outdoor Security Solutions
Whenever an area needs to be secured, the most common solution is surrounding the area's perimeter with a fence. Many cases require for the secure area to be extended beyond the confines of the fence; that means to create an external perimeter so that the approach of an intruder will be detected well before he reaches the inner area. Proper Perimeter Security means tailoring a solution based on Virtual Fencing and Physical Fencing.
Virtual Fencing
Perimeter Security can be improved substantially by implementing a "Virtual Fence". In principle it is a combination of detecting elements based on Laser Radar and other optical means that provide for intruder detection in a zone around the secured perimeter. Virtual Fencing allows for easy and fast deployment around critical targets like airplanes, where Physical Fencing is not an option.
Virtual Fencing includes part of all of the following elements:
Physical Fencing
Physical Fencing means a physical obstacle enhanced by the use of sensing elements that detect intrusion. Those elements detect the presence of an intruder by sensing his physical effect on them, which means his touch, the impact of his weight while walking, etc.
Physical security describes measures that are designed to deny access to unauthorized personnel (including attackers or even accidental intruders) from physically accessing a building, facility, resource, or stored information; and guidance on how to design structures to resist potentially hostile acts. Physical security can be as simple as a locked door or as elaborate as multiple layers of barriers, armed security guards and guardhouse placement. Good physical security uses the concept of layered defence, in appropriate combinations to deter and delay intrusions (passive defence), and detect and respond to intrusions (active defence). Ultimately it should be too difficult, risky or costly to an attacker to even attempt an intrusion. However, strong security measures also come at a cost, and there can be no perfect security. It is up to a security designer to balance security features and a tolerable amount of personnel access against available resources, risks to assets to be protected and even aesthetics. There are also life-cycle sustaining costs to consider.
Physical security is not a modern phenomenon. Physical security exists in order to deter or prevent persons from entering a physical facility. Historical examples of physical security include city walls, moats, etc.
The technology used for physical security has changed over time. While in past eras, there was no passive infrared (PIR) based technology, electronic access control systems, or video surveillance system (VSS) cameras, the essential methodology of physical security has not altered over time. Fundamentally, good physical security is a combination of defensive principles designed to:
... to intrusions into critical physical spaces. The first two actions of deter and delay are considered passive defence, while the remaining are active in nature
Perimeter Security
Bollards
Remotely activated or used in conjunction with intelligent authorization systems, automatic bollards allow the responsive, effective control of access. The rising bollard is built to withstand even the most severe attacks while being clearly visible toon coming traffic, yet visually unobtrusive. A new addition to our access control catalogue, the Rising Kerb or step barrier offers excellent protection where there could be a risk of vehicle theft or vandalism to a barrier arm. The Rising Kerb can be raised or lowered in just 2-3 seconds and is of high resistance to impact from cars or vans and provides secure and effective vehicle control.
