What is the primary function of a Global Positioning System (GPS) in security?

The primary function of a Global Positioning System (GPS) in security is to locate vehicles in real-time. GPS technology provides precise positioning information, enabling security personnel to monitor the location and movement of vehicles. This functionality is crucial for various applications, such as fleet management, theft recovery, and monitoring the transportation of valuable goods. The ability to track vehicles as they move allows for prompt responses to security incidents, ensuring a rapid and effective reaction to potential threats.

In contrast, the other options do not align with the core purposes of GPS technology in security. For instance, tracking financial transactions does not involve location services, while managing employee schedules and monitoring customer interactions pertain more to operational management tasks that do not require real-time location tracking. GPS technology specifically excels in providing geographic positioning, which is essential for real-time vehicle tracking in security applications.
