Final answer:
Sarah's statement about the effectiveness of a high fence for security is correct, as fences act as a physical barrier to intruders. Mark's claim that lighting is not important for security is incorrect; good lighting is in fact a critical part of any comprehensive security system in a logistics facility.
Step-by-step explanation:
In the discussion between Mark and Sarah about security in logistics facilities, Sarah's point of view aligns better with the best practices in security management. While Mark suggests that lighting is not an important element, security experts would typically disagree. Good lighting can deter potential intruders by increasing visibility, making it more difficult for unauthorized persons to approach or enter a facility undetected. Therefore, lighting is indeed a crucial aspect of a security system.
On the other hand, Sarah mentions that a high fence creates a barrier to possible intruders, which is a widely accepted security measure. A high fence acts as a physical deterrent and can delay or even prevent unauthorized entry, complementing other security measures such as surveillance cameras and access control systems.
In conclusion, between the two, Sarah is correct in recognizing the significance of a high fence as a security measure. However, it is important to note that comprehensive security systems incorporate a variety of elements, including adequate lighting, fencing, surveillance, access controls, and other deterrent measures.
