Internal Barriers
Have you ever watched a trespasser come into a building? He walks slowly, he looks around, and his eyes go right and left. He is 8 feet into your lobby and sees the turnstile and realizes he has been denied access. So he proceeds to the security desk with a simple question of employment.
Barriers are psychological deterrents allowing unauthorized access. Turnstiles and access control are physical barriers that control entry points and complement your security program and your security officers.
Functions of structural and/or natural barriers include:
1.
Define protection area boundaries.
2.
Delay—slow traffic or access. Consider speed bumps.
3.
Direct access to garages, parking lots, and building entrances.
4.
Deny unauthorized access and allow only authorized visitors.
Designing Security and Layout of Site
Designing security into a new or renovated complex can begin with the exterior or interior. Since we are discussing protective barriers in this chapter, let us assume we started the layout discussion on the outside.
Your main lines of defense are your perimeter barriers or the outer edge to your property line. The second line of defense is the exterior of the building, which includes the roof and roof access and walls, doors, and windows. Remember to eliminate all but essential doors and windows. If this is not done in early stages, they will have to be alarmed and set up as emerging exits. Also included should be adequate lighting (cost-effective) that meets standard and supports exterior closed-circuit TV (CCTV). The third line of defense is the interior. It is important to reduce access points by using access control and have specific areas zoned for access control and added security.
