Which CPTED principle is demonstrated by improving lighting and sightlines to increase natural surveillance?

• A. Improve lighting and maintain sightlines.
• B. Install more cameras.
• C. Increase fencing with limited visibility.
• D. Remove lighting to save energy.

Answer: (A)

Natural Surveillance is the CPTED principle at work here. It uses the design of the surroundings to maximize visibility so people can observe activity and be seen themselves. Improving lighting and keeping sightlines clear increases the chances that people—whether residents, pedestrians, or security personnel—can notice what’s happening, which deters crime because offenders avoid well-observed areas. Relying on cameras changes the approach to monitoring through technology rather than enhancing the environment’s own visibility. Increasing fencing with limited visibility blocks sightlines, reducing the chance for natural observation. Removing lighting would cut visibility and undermine safety.
