Which of the following would NOT typically be a recognized security measure?

Operation identification is a crime prevention strategy that focuses on marking property and encouraging individuals to mark their valuables with identifiable information. While it is an important technique used to deter theft and assist in recovery, it does not fall under the category of recognized security measures that physically prevent unauthorized access or provide immediate surveillance of an area.

On the other hand, outside landscaping, aerial lighting, and security cameras are all physical security measures that enhance the safety and security of a property. Effective landscaping can create natural barriers, aerial lighting increases visibility and deters criminal activity during nighttime, and security cameras provide surveillance and can help in monitoring and recording events for later review. These measures actively contribute to creating a secure environment and are commonly recognized in security protocols and practices.
