Which pair represents common performance measurements of entry and access control systems?

• A. Throughput, the measure of time; False readings in the measure of acceptance
• B. Response time and error rate
• C. Availability and reliability
• D. Number of users and accessibility

Answer: (A)

Performance of entry and access control centers on how fast the system can process people and how accurately it makes access decisions. Throughput measures the rate of processing—how many users can be checked and granted access per unit time. This is crucial in busy facilities because it directly affects queues and wait times. The second aspect, false readings in acceptance, refers to errors in the system’s decision to grant access, typically the risk of false accepts where an unauthorized person is admitted. Together, throughput and acceptance accuracy give a clear picture of both the system’s capacity and its security performance. Other options emphasize latency, uptime, or user count, but they don’t capture both how many people can be processed and how accurately access is granted in one pair.
