Access control systems play a crucial role in preventing unauthorized access to a building. These systems include mechanisms such as card readers, biometric scanners, keypads, and electronic locks that regulate who can enter specific areas at any given time. By implementing these systems, organizations can ensure that only authorized individuals, such as employees or contractors who possess the correct credentials, can gain entry.

This measure adds a layer of security by automatically controlling access and can often be integrated with alarm systems or monitoring systems to enhance overall safety. Surveillance cameras, while they help monitor areas and can deter potential intruders, do not actually prevent access; they only allow for observation after an event occurs. Security personnel can also deter unauthorized access actively and respond to incidents, but they rely on human presence and are not a standalone solution. Emergency lighting systems are essential for safety during power outages or emergencies, but they do not contribute to access control in a proactive manner. In summary, access control systems are specifically designed to manage and restrict entry, making them an effective security measure for protecting a building from unauthorized access.
