Which of the following is a key component of an electronic access control system?

An access control panel is a fundamental element of an electronic access control system because it serves as the central hub that manages and regulates access to secured areas. The access control panel communicates with various components such as card readers, biometric scanners, and locks. It processes the information received from these devices to determine whether an individual has the proper credentials to gain entry, thereby controlling who can access specific locations within a facility.

While the other components listed, like surveillance cameras, alarm systems, and motion detectors, play important roles in overall security, they do not directly manage access control. Surveillance cameras monitor and record activity, alarm systems signal breaches or emergencies, and motion detectors enhance security by detecting movement. However, only the access control panel directly handles authorization and access management, making it a critical component of an electronic access control system.
