Which of the following is NOT an advantage of using Electronic Access Control systems?

In the context of Electronic Access Control (EAC) systems, higher maintenance costs are not considered an advantage. Instead, one of the notable benefits of EAC systems is their ability to provide enhanced security. These systems restrict unauthorized access, allowing only designated individuals to enter certain areas, thereby significantly reducing the risk of theft, vandalism, or other security breaches.

EAC systems also facilitate detailed access records, which are crucial for monitoring who accessed specific areas and when, adding an additional layer of accountability. Furthermore, modern EAC solutions are often designed with user-friendliness in mind, making it easier for personnel to manage access controls without extensive training.

High maintenance costs, however, are typically seen as a disadvantage associated with some types of EAC systems, as they can lead to budget constraints or necessitate resource allocation that detracts from other security measures. Hence, while the first three options represent clear benefits of implementing Electronic Access Control systems, elevated maintenance costs do not align with the advantages of such systems.
