CSS CSS Security Technology & Systems 1 — Questions and Answers
Question 1: Which type of CCTV camera is best suited for monitoring a wide open area such as a parking lot?
- Fixed indoor dome camera
- Pan-tilt-zoom (PTZ) camera (Correct answer)
- Pinhole covert camera
- Infrared indoor bullet camera
Correct answer: Pan-tilt-zoom (PTZ) camera
PTZ cameras can be remotely controlled to pan, tilt, and zoom across large open areas, providing flexible and broad surveillance coverage.
Question 2: An intrusion detection system (IDS) generates a large number of false alarms. What is the most likely consequence for security operations?
- Officers become more alert to real threats
- Alarm fatigue causes officers to disregard or delay response to alarms, including real ones (Correct answer)
- False alarms automatically reset the system for better accuracy
- The system shuts down to prevent damage
Correct answer: Alarm fatigue causes officers to disregard or delay response to alarms, including real ones
Frequent false alarms lead to alarm fatigue, where officers begin ignoring alerts, significantly increasing the risk of missing a genuine security event.
Question 3: What is the primary advantage of an IP-based CCTV system over an analog system?
- IP cameras are less expensive in all cases
- IP systems offer higher resolution, remote access, and easier integration with other security systems (Correct answer)
- Analog systems have no disadvantages compared to IP
- IP systems require no network infrastructure
Correct answer: IP systems offer higher resolution, remote access, and easier integration with other security systems
IP-based CCTV provides superior image quality, remote monitoring capability, and integration with access control and alarm systems.
Question 4: A CSS supervisor is responsible for ensuring CCTV footage is retained. The primary reason for footage retention policies is to:
- Allow officers to watch their own patrols for entertainment
- Support post-incident investigations and meet legal or contractual requirements (Correct answer)
- Save storage space by deleting footage quickly
- Prevent employees from knowing they are monitored
Correct answer: Support post-incident investigations and meet legal or contractual requirements
Footage retention policies ensure that recordings are available for incident investigations and satisfy legal, insurance, and contractual obligations.
Question 5: Which sensor type is most appropriate for detecting the opening of a door or window in an intrusion detection system?
- Passive infrared (PIR) motion sensor
- Magnetic contact switch (Correct answer)
- Vibration sensor
- Smoke detector
Correct answer: Magnetic contact switch
Magnetic contact switches detect the separation of two magnets when a door or window is opened, triggering an alarm.
Question 6: A security supervisor receives a request to grant a contractor temporary access credentials. The best practice is to:
- Issue the contractor a permanent master credential
- Create time-limited credentials that expire when the contract ends and log all access (Correct answer)
- Share an existing officer's credential with the contractor
- Allow the contractor to use an unsecured entrance
Correct answer: Create time-limited credentials that expire when the contract ends and log all access
Temporary, time-limited credentials with access logging ensure contractor access is controlled, auditable, and automatically revoked.
