What actions can security personnel take to create a deterrent effect?

Increased visibility and enforcement of rules by security personnel serve as a primary deterrent against undesirable behavior or potential criminal acts. When security personnel are visible, it creates an atmosphere of safety and vigilance. Individuals are less likely to engage in illicit activities when they know that security staff is present and attentive. Furthermore, actively enforcing rules reinforces the seriousness of compliance and the consequences of violating these rules, which contributes to a perception of readiness and authority. This proactive approach effectively discourages negative behavior or criminal activity, as potential offenders recognize the consequences of their actions in the presence of vigilant security measures.

The other options may not effectively contribute to a deterrent effect in the same way. Reducing the number of staff on duty could create an impression of vulnerability, while marketing campaigns and providing free services may not have a direct impact on individual behavior or compliance with security protocols.
