Final answer:
Effective security patrols cover as much of the property as possible while following unpredictable routes to deter unauthorized activities and address security risks over the entire area.
Step-by-step explanation:
To be effective, security patrols should cover as much of the property as possible, but follow different routes so as not to be predictable. The correct answer is D) cover as much of the property as possible, but follow different routes so as not to be predictable. Security patrols that are unpredictable are more likely to deter unauthorized access or activities because potential intruders cannot easily guess the patrol patterns. Additionally, by changing routes regularly, security personnel are more likely to encounter and address potential security risks throughout the property.
A predictive security patrol pattern can be easily learned by potential intruders, making certain times and areas more vulnerable to breaches. Therefore, it is important that the security patrols are not only comprehensive in terms of area covered but also vary their patterns to maintain an element of surprise and effectiveness in their security measures.
