Which of the following statements about CCTV is not true? ? A. CCTV is a good example of a deterrent system. ? B. CCTV is a good example of an automated intrusiondetection system. ? C. CCTV is effective at deterring security violations. ? D. CCTV is a good example of a detection system
The correct answer and explanation is:
Correct Answer: B. CCTV is a good example of an automated intrusion detection system.
Explanation:
Closed-Circuit Television (CCTV) systems are widely used in security for monitoring and recording activities in specific areas. While they are versatile tools, the characterization of CCTV as an automated intrusion detection system is not accurate. Here’s why:
A. CCTV is a good example of a deterrent system.
This statement is true. CCTV cameras act as a visible deterrent to potential intruders. Knowing they are being watched often discourages unauthorized activities, such as theft or vandalism. Their presence can help establish a perception of surveillance, which can reduce the likelihood of security breaches.
C. CCTV is effective at deterring security violations.
This statement is also true. By deterring malicious actors, CCTV contributes to crime prevention. For instance, studies have shown that areas with visible CCTV systems often experience lower rates of criminal activity compared to unmonitored locations.
D. CCTV is a good example of a detection system.
This is true as well. CCTV systems can be used to detect unusual or unauthorized activities in real-time, especially when monitored by human operators. They provide valuable visual evidence of security breaches, which can be reviewed later to identify culprits or understand incidents.
B. CCTV is a good example of an automated intrusion detection system.
This is not true. While modern CCTV systems can incorporate analytics like motion detection or facial recognition, they are not inherently designed as automated intrusion detection systems. Automated systems typically include specialized sensors and algorithms to identify intrusions without human intervention, often triggering alarms or alerts. Traditional CCTV systems, on their own, rely on human monitoring and interpretation for detecting intrusions.
In summary, CCTV is primarily a tool for deterrence and detection, but it lacks the fully automated capabilities of dedicated intrusion detection systems.
