ANSI / ASIS PAP.1-2012 Physical Asset Protection APP Practice Exam

Lighting is a physical security tool that enhances visibility and supports detection and monitoring. Its deterrent value comes not only from creating a sense of security, but from actually enabling guards, cameras, and responders to observe and react to activity. Relying on lighting alone as a psychological deterrent assumes the lights will always be on, never fail, and always reveal intruders—the reality is that lights can burn out, be compromised, or leave dark gaps that an intruder can exploit.

Therefore, lighting should be part of a layered defense, integrated with barriers, access controls, alarms, and patrols. When combined with other measures, it strengthens actual protection rather than just influencing perception.
