Which type of detector is best suited for detecting heat from a human body moving through a protected area?
Answer: Passive Infrared (PIR) detector
PIR detectors sense the infrared energy emitted by warm bodies moving through their detection field, making them ideal for motion detection inside buildings.
What is the primary purpose of 'anti-passback' in an access control system?
Answer: Prevents a credential from being used to re-enter a zone before it has been used to exit
Anti-passback enforces the rule that a card must be used to exit before it can be used to enter again, preventing credential sharing.
A security integrator is proposing a networked access control system. Which component serves as the 'brain' that manages door control hardware?
Answer: Access control panel/controller
The access control panel or controller processes credential data from readers and makes the decision to grant or deny access, controlling the locking hardware.
What differentiates a 'dual-tech' motion detector from a single-technology detector?
Answer: It requires two different sensing technologies (e.g., PIR + microwave) to both trigger before sounding an alarm
Dual-tech detectors require both their sensing technologies to trigger simultaneously, significantly reducing false alarms in challenging environments.
Which surveillance camera type is best for covering large open areas like parking lots from a single mounting point?
Answer: PTZ (Pan-Tilt-Zoom) camera
PTZ cameras can pan, tilt, and zoom to cover wide areas, track moving subjects, and provide detailed close-ups from a single installation point.
What is a 'monitoring center' (also called a central station) in the context of security alarm systems?
Answer: A 24/7 facility that receives alarm signals and dispatches appropriate response
A central monitoring station operates 24/7 to receive alarm signals from customer systems and coordinate emergency response such as police or fire dispatch.
Which communication pathway is considered most reliable for transmitting alarm signals from a customer's premises to a monitoring center?
Answer: Cellular/radio backup with broadband primary
A dual-path setup using broadband as the primary and cellular as the backup provides the highest reliability, as it has redundancy if one path fails.
