The answer is A. All other answers are physical ACCESS controls, while cameras are physical DETECTION devices.

It is rare any one of us gets to say this quite so triumphantly and dogmatically on account of the subjective nature of a lot of these questions but I can ASSURE you with complete certainty that the answer is A. Please navigate to the CompTIA Network+ n10-008 Exam Objectives. Look under section 4.5 "Explain the importance of physical security" Camera is listed under detection methods, case closed. The answer is A. I was formerly under the impression it was ACV, for those also labouring under that misapprehension, please consult the exam objectives and you'll find that Access Control Vestibules are listed as "Prevention Methods" and NOT detection methods. Physical was not the word to focus on, they're all physical methods.

Hi guys, I'd pick C. Searched the web for companies that make access control vestibules, and came across Hamillton's Entrance System Vestibule: Hamilton's Entrance System Vestibule provides a tough first line of defense in preventing fire-arms from entering your building, school or university. The unit incorporates key features such as metal detection, motion sensors and door locking controls with warning alerts to help prevent takeover robberies. https://hamiltonsecuritysolutions.com/solutions/entrance-security/entrance-security-vestibule.html A camera will not detect something like a weapon, then cameras cannot be used in the dark to detect anything or anyone

The answer is A. Everyone saying its C is trying to make you fail because they dont want their jobs to be taken over by newbies.

it is A or C?

A is the correct answer - an access control vestibule prevents access, not detect it.

A. Cameras are considered a physical security detection device. Cameras are used for surveillance and monitoring purposes, allowing security personnel to observe and detect potential threats or security breaches. They are often used in combination with other physical security measures such as access control systems, alarms, and security guards. Cameras can also provide valuable evidence in the event of a security incident.

A is the correct answer

Hear me out - Access control vestibules can have metal detector built in, hence why they may be considered a physical security detection device. They really like to trick people with these questions.

A. Cameras Cameras are considered physical security detection devices because they are used to monitor and detect unauthorized access or suspicious activity in a given area. Biometric readers and access control vestibules are access control devices, and locking racks are used for securing physical equipment but are not detection devices.

Physical.

Access control vestibules, also known as security or mantrap vestibules, are a highly effective means of hardening commercial security. These enclosed entryways are designed to restrict and monitor access to a building by allowing only one person to enter at a time, typically through a series of interlocking doors. How camera is not also a physical detection measure, I don't know.

Detection devices include door alarms, glass breaks, and motion sensors C. Access control vestibules An access control vestibule, or mantrap, is part of a physical access control system that typically provides a space between two sets of interlocking doors.

GPT picks (A): "(A) Cameras are considered a physical security detection device. Cameras, also known as surveillance cameras or CCTV (Closed-Circuit Television) cameras, are used to visually monitor and record activities in a specific area. They are a common component of physical security systems and are used to detect and deter unauthorized access or suspicious activities. (B) Biometric readers, (C) Access control vestibules, and (D) Locking racks are also components of physical security systems, but they are not typically categorized as "detection" devices"

key word physical detection

A cameras. Access control vestibules are not considered a physical security detection device as they are a security mechanism used to control access to a secure area, but they do not detect security incidents. Instead, they physically restrict entry and exit to an area by allowing only authorized personnel to pass through. For example, a vestibule may consist of a secure entry and exit point, with a turnstile or locked door, that requires a key card, biometric reader, or other form of authentication.

Cameras are often found in data storage rooms, computer labs, co-location / data centers, and anywhere else where physical security is beneficial. Video surveillance is generally a combination of human monitoring of live or recorded feeds and image processing by software designed to detect particular patterns in video images. Cameras can optionally be run continuously for round-the-clock surveillance, or be triggered by software detection of heat or movement in the field of vision.
