Aviation and Airport Security Practice Test 2025 - Free Practice Questions and Study Guide

Surveillance cameras are extensively used at airports primarily to monitor activities and deter unlawful behavior in secured areas. The presence of these cameras acts as a deterrent to potential criminals, as they know they are being watched and recorded. This enhances overall security, helping to prevent acts such as theft, vandalism, or other unauthorized activities that could compromise the safety of passengers and staff.

Furthermore, surveillance footage provides valuable evidence in the event of an incident, aiding security personnel in investigations and ensuring that any violations of airport regulations are addressed promptly. This use of monitoring technology is critical in maintaining the high security standards required at airports, which are often targets for criminal activities due to the large number of people and valuable assets present.

The other options, while potentially relevant in different contexts, do not directly align with the primary security role that surveillance cameras play at airports. For instance, while customer service inquiries, flight departures, and luggage handling are all important aspects of airport operations, they are not the main functions of surveillance cameras. Hence, the correct answer emphasizes the cameras' role in enhancing security and preventing crime.
