How do different camera systems in the store function?

The correct answer indicates that camera systems in the store serve a multifaceted role, primarily focused on observing ongoing activities and providing evidence. This encompasses monitoring various aspects of store operation, including customer behavior, employee actions, and potential theft or loss prevention scenarios.

The camera systems are designed to capture visual evidence that can be crucial in incidents of theft or disputes. This capability not only aids in loss prevention but also enhances overall store safety and operational efficiency. By having a comprehensive view of the store environment through surveillance, management can identify patterns or issues that may require intervention, thus improving the overall security posture of the establishment.

The other options limit the function of camera systems to specific areas, such as only monitoring employees or solely focusing on sales transactions, which does not capture the broader scope and utility of surveillance in a retail context. Additionally, while inventory management is an important aspect of retail operations, camera systems are not primarily designed for this purpose, further distinguishing the correct answer as the most accurate representation of the cameras' purpose within the store.
