CSS Security Technology and Solutions 2 — Questions and Answers
Question 1: Which type of access control system uses unique biological characteristics to verify identity?
- Biometric access control (Correct answer)
- Proximity card readers
- Keypad PIN systems
- Mechanical key locks
Correct answer: Biometric access control
Biometric access control authenticates individuals using physical traits such as fingerprints, iris patterns, or facial recognition.
Question 2: What does 'PACS' stand for in the security industry?
- Physical Access Control System (Correct answer)
- Perimeter Alarm and Camera System
- Personnel Authentication and Credential Service
- Primary Alert and Communication Station
Correct answer: Physical Access Control System
PACS (Physical Access Control System) manages and restricts entry to facilities through electronic credentials and hardware.
Question 3: A customer wants to detect motion in a parking lot at night. Which camera feature is most critical?
- Low-light or infrared capability (Correct answer)
- High optical zoom
- Pan-tilt-zoom motorization
- Wide dynamic range
Correct answer: Low-light or infrared capability
Low-light or infrared (IR) cameras can capture clear images in darkness, making them essential for nighttime parking lot surveillance.
Question 4: Which video surveillance storage method continuously overwrites oldest footage when capacity is reached?
- Circular/loop recording (Correct answer)
- Event-triggered recording
- Cloud archival storage
- WORM (Write Once Read Many) storage
Correct answer: Circular/loop recording
Circular or loop recording automatically overwrites the oldest video data once storage is full, ensuring continuous coverage.
Question 5: In an intrusion detection system, what is a 'zone'?
- A defined area or circuit monitored by one or more sensors (Correct answer)
- The secured server room for alarm control panels
- A geographic sales territory for the security dealer
- The wireless frequency band used by sensors
Correct answer: A defined area or circuit monitored by one or more sensors
A zone is a specific area or sensor circuit that the alarm panel monitors independently, allowing precise identification of where an alarm triggered.
Question 6: What is the primary advantage of IP-based security cameras over traditional analog cameras?
- Higher resolution and remote accessibility over a network (Correct answer)
- Lower cost per unit
- No need for any cabling infrastructure
- Immunity to cybersecurity threats
Correct answer: Higher resolution and remote accessibility over a network
IP cameras offer significantly higher resolution and can be accessed, managed, and recorded remotely over a network.
Question 7: Which technology allows multiple building systems (access control, HVAC, fire, cameras) to communicate on a single integrated platform?
- Building Management System (BMS) integration (Correct answer)
- PSTN dial-up monitoring
- Standalone panel architecture
- Analog multiplexing
Correct answer: Building Management System (BMS) integration
A Building Management System (BMS) or integrated security platform unifies disparate building systems for centralized monitoring and control.
