Which type of security system is designed to detect unauthorized entry?

The type of security system that is specifically designed to detect unauthorized entry is known as an Intrusion Detection System (IDS). This system monitors a designated area, typically using sensors or alarms, to identify potential break-ins or intrusion attempts. It is equipped to analyze patterns of activity and can alert security personnel or trigger alarms when it detects suspicious behavior or unauthorized access, thus preventing potential security breaches.

An IDS is essential within various environments, such as commercial buildings, data centers, and even residential settings, where safeguarding against unauthorized individuals is a priority. It plays a crucial role in maintaining security by providing real-time alerts and assists in both preventing theft and deterring criminal activity.

Other systems listed have distinct purposes. A Network Security System primarily protects computer networks from cyber threats, whereas an Access Control System regulates who can enter specific physical or digital spaces. An Environmental Monitoring System focuses on conditions such as temperature and humidity rather than unauthorized access. Each of these systems serves its unique function but does not particularly concentrate on detecting unauthorized entry like an Intrusion Detection System does.
