Deterrence in security refers to the prevention of criminal behavior through a visible security presence. This concept rests on the idea that the more visible security measures are—such as guards, surveillance cameras, and security signage—the less likely individuals will engage in unlawful activities. The rationale is that potential intruders or criminals assess the likelihood of getting caught or facing consequences; thus, a strong security presence serves as a psychological barrier that discourages crime.

While physical barriers can stop intruders and the identification of criminals is essential for law enforcement, such measures do not inherently deter crime on a broader level in the same way that a strong visible security presence does. Similarly, reporting crimes is a response to security breaches that have already occurred rather than a proactive measure aimed at preventing crime through deterrence. Hence, the notion of deterrence is fundamentally linked to how the visibility of security influences behavior.
