The statement regarding site lighting being a deterrent to unauthorized entry while enhancing observation is accurate and highlights the critical role of lighting in physical security measures. Properly designed and implemented site lighting serves two main functions:

1. **Deterrence of Unauthorized Entry**: Well-lit areas can discourage potential intruders from attempting to breach security barriers because visibility increases the likelihood of detection. Criminals tend to avoid well-lit environments for fear of being observed, which makes lighting a proactive security measure.

2. **Enhanced Observation**: Adequate lighting improves the ability of security personnel to monitor the premises and identify potential security threats. It also helps in the surveillance processes, whether through direct human observation or the use of cameras. The clarity provided by good lighting allows for better image capture at night, aiding in identification and reporting of suspicious activities.

This understanding emphasizes the importance of integrating effective lighting as part of a comprehensive security strategy, rather than viewing it as merely decorative or ineffective on its own. Other options suggest limitations to the role of site lighting, which do not align with the established principles of security and environmental design.
