CPTED (Crime Prevention Through Environmental Design)
A 40-year-old security discipline based on four principles: natural surveillance, natural access control, territorial reinforcement, and maintenance.
In Detail
Crime Prevention Through Environmental Design (CPTED) originated with C. Ray Jeffery in 1971 and was refined by Tim Crowe and others. It is adopted by ASIS International, the International CPTED Association, and most urban planning departments — including the City of Houston. Its four principles — natural surveillance, natural access control, territorial reinforcement, and maintenance — operationalize through modern technology like elevated cameras (surveillance), LPR on ingress (access control), and visible monitored deterrent presence (territorial reinforcement).
Why It Matters in Houston
CPTED is the framework executive risk and insurance buyers use to justify site-security spend on a designed, evidence-based rationale rather than a cost line. It is referenced throughout the Guardtress strategic brief at /strategic.
