What is one effective way to deter criminal activity in a given area?

Increased visibility of security personnel is an effective way to deter criminal activity because the presence of security guards serves as a psychological deterrent. When potential offenders see security personnel actively monitoring an area, they are less likely to engage in criminal behavior due to the increased risk of being caught. This proactive approach not only discourages crime but also fosters a sense of safety and security among residents and visitors. Additionally, visible security can quickly respond to incidents, further reinforcing the notion that illegal activities will not be tolerated.

The other options, while they may have some impact, are generally less effective as standalone measures. For example, reduced lighting can actually create opportunities for crime by providing cover for offenders. Raising property fences may enhance physical security but does not address the psychological impact that visible security can have. Lastly, while installing surveillance cameras can help in documenting incidents and providing evidence after the fact, it does not deter crime as effectively as the presence of security personnel who can intervene in real time.
