The effectiveness of site lighting in security is significantly enhanced by the presence of fixed security posts or patrols. This is because having personnel actively monitoring an area can deter criminal activity and provide immediate response capabilities. When security personnel are stationed in well-lit areas, they benefit from improved visibility, allowing them to detect unauthorized individuals or activities more effectively. In essence, the combination of adequate lighting and active security presence creates a comprehensive approach to security, making it less likely for threats to occur.

While factors such as plants and landscaping, color selection of lights, and lighting height above ground do contribute to overall lighting effectiveness, they do not directly enhance the security function in the same way as security personnel do. Landscaping can introduce shadows that might obscure visibility, color selection influences visibility and ambiance, and lighting height can affect the distribution of light. Nonetheless, none of these components can substitute for the vigilant eyes of security personnel actively engaged in protecting the area.
