What is Crime Prevention through Environmental Design (CPTED)?

Crime Prevention through Environmental Design (CPTED) minimizes the possibility of crime and reassures the safety and well-being of the public.

Crime Prevention through Environmental Design (or CPTED) is a proactive security model using the four principles of natural surveillance, access control, territorial reinforcement, and space management. Using CPTED is effective because it minimizes the possibility of crime and reassures the safety and well-being of the public. Through the SloanSecure™ Process, we analyze your site and security risks to create a safe and effective intrusion detection system for your facility, while implementing core CPTED principles.

Natural Surveillance

With the presence of both natural and technological types of surveillance, Sloan can reduce the appeal of an area as a possible target. Most criminals will look for an easy getaway and hide from plain sight. Carefully designed surveillance makes it possible to view all surrounding areas inside your facility with no possibility for deception. A natural element of surveillance can be as straightforward as lighting public areas, reducing the places someone can hide, or preventing any blind spots in your hallways and parking lots. The goal is to make a perpetrator feel as if there are no easy access points and getaway.

Access Control

Access Control

The purpose of access control is to make a distinct path for people in transit. To deter someone to commit a crime, there are physical and symbolical barriers. Natural access control can be by landscaping a controlled area and keeping those from straying from a specific pathway. One of the ways Sloan designs to prevent incidents is by restricting access through crash-rated barriers and entry point systems (ECP/ACP). The goal of access control is to prevent the criminal from having direct access to a known target.

Territorial Reinforcement

Territorial reinforcement relies on those who utilize the space and have a feeling of ownership over the area. This encourages crime reporting and to be able to recognize an intruder. Sloan often deploys this by implementing a card access system at the site that makes employees feel secure.

Space Management

Proper maintenance and cleanliness of a site and the security systems surrounding it are just as critical as any other principle. It implies that the site is cared for and looked after routinely. By clearing all signs of vandalism, trash and keeping the area clean will discourage vandals to commit more crimes. Surveillance cameras and other security measures should be regularly maintained to demonstrate that the building is actively secured.

In summary 'CPTED' uses these four main strategies to prevent crime and vandalism. Creating a well-lit environment with labeled paths and cut shrubs can contribute to a well-secured area. Having technical and natural preventative features working together can improve the quality of security around a facility.
