CPTED (pronounced sep-ted) is a multi-disciplinary approach to deterring criminal behavior through environmental design. Michael Mercer Consulting is a highly sought-after certified Crime CPTED educator, providing expert knowledge to architects, city planners, builders, and businesses to reduce the risk of crime and increase the value of properties, thereby increasing the value of life itself!

The main goal of CPTED is to alter the physical design of the communities in which people reside and congregate in order to deter criminal activity.

CPTED uses planned strategies in neighborhoods and organized living communities to reduce the risk of crime. Natural surveillance strategies, such as: placing windows overlooking sidewalks and parking lots; creating landscape designs that provide surveillance, especially in proximity to designated points of entry and opportunistic points of entry; using transparent weather vestibules at building entrances; and security lighting act as crime deterrents.


CPTED Michael Mercer Consulting


CPTED is based on a set of four design and usage concepts that can lead to a reduction in the incidence and fear of crime, and an improvement in the quality of life. These concepts are defined briefly as follows:

  1. Surveillance: Involves the use of electrical and mechanical devices, and the location of physical features, activities, and people to provide good visibility in the environment. Creates a risk of detection for offenders and a perception of safety for legitimate users.
  2. Access Control: Employs electrical and mechanical devices, people, and natural measures to create a perception of risk to offenders and deny them access to targets. Also guides legitimate users safely through the environment.
  3. Territorial Reinforcement: Uses physical features and signs to define ownership and control activities in the environment. Delineates spaces with limited or no public access.
  4. Maintenance: Allows the continued use of spaces for their intended purposes. Maintains the effectiveness of measures employed for surveillance, access control, and territoriality.
