Which of the following is a common objective of an Intrusion Detection System?

1. Prevent unauthorized entry

2. Track movement within a building

3. Provide video surveillance

4. All of the above

The correct answer is: All of the above

An Intrusion Detection System (IDS) is designed with multiple objectives to enhance security. One of the primary goals is to prevent unauthorized entry; this is fundamental to ensuring that individuals who do not have permission to access a location are kept out. The system achieves this by using various sensors and alerts to notify security personnel of any breaches. Additionally, tracking movement within a building is another important function of an IDS. This capability allows businesses or homeowners to monitor the presence and activities of individuals within their premises, which can be crucial for identifying suspicious behavior or potential threats. Furthermore, many modern intrusion detection systems integrate video surveillance as part of their security measures. This combination of video monitoring with detection technology provides a comprehensive overview and serves as both a deterrent and a method for reviewing incidents after they occur. Since a well-designed Intrusion Detection System encompasses the prevention of unauthorized entry, tracking of movement within the premises, and the provision of video surveillance, stating that “All of the above” accurately reflects the comprehensive role such systems play in modern security protocols.
