What is the primary function of a video analytics system integrated with CCTV?
Answer: Automatically analyze video to detect specific events or behaviors without constant human monitoring
Video analytics software processes camera feeds in real time to automatically detect defined events—loitering, perimeter breach, abandoned objects—reducing reliance on continuous human monitoring.
Which wiring topology provides the highest fault tolerance for a fire alarm system by allowing the system to continue operating if a single break occurs in the circuit?
Answer: Class A (Style D/E) wiring
Class A wiring loops back to the panel on both ends, so a single open circuit does not disable the devices; the panel can still communicate with all devices from the other direction.
What is a 'duress code' in the context of access control or alarm systems?
Answer: A secondary PIN that silently alerts a monitoring station that the user is under coercion
A duress code looks like a normal entry PIN but secretly triggers a silent alarm to notify security personnel that the user is being forced to grant access.
In electronic security, what does 'REX' stand for?
Answer: Remote Exit — a sensor or button that signals a controlled door to unlock for egress
REX (Request to Exit) devices—motion sensors or push buttons—detect when someone approaches a door from the secured side and signal the access controller to release the lock for safe egress.
Which standard published by ASIS International provides guidance on the design, operation, and evaluation of security management systems?
Answer: ASIS/ANSI ASMS-2022 (Security Management Systems)
The ASIS/ANSI ASMS standard provides a management system framework for security programs, including planning, implementation, evaluation, and continual improvement aligned with ISO high-level structure.
What is the main purpose of using a 'Wiegand' interface in legacy access control readers?
Answer: Transmit card credential data from the reader to the access control panel using a simple unencrypted serial format
The Wiegand protocol transmits card data as a simple unencrypted serial signal, which is its primary vulnerability—the data can be intercepted and replayed; OSDP was developed as a secure replacement.
Which of the following best describes 'convergence' in modern security programs?
Answer: The integration of physical security and cybersecurity into a unified risk management program
Security convergence unifies physical security (access control, surveillance) and information security (cyber) under a single governance framework, recognizing that threats often span both domains.
