CPTED Basic Concepts:

Natural Surveillance

Natural surveillance is the capacity to see what's occurring without having to take special

measures to do so. Clear direct views, such as
is provided by windows, provide natural surveillance. An adult presence does the same, with the notable impact on behavior.

If responding to call for help or a loud noise requires opening a solid door or stepping
around a blind corner, natural surveillance is missing, and response may be too little, too late. We see the aftermath, but we don’t know what initially occurred. If lighting is inadequate, we have even less hope of determining what happened.
