CSS Security Technology & Systems Flashcards

Which type of CCTV camera is best suited for monitoring a wide open area such as a parking lot?

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.

An intrusion detection system (IDS) generates a large number of false alarms. What is the most likely consequence for security operations?

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.

What is the primary advantage of an IP-based CCTV system over an analog system?

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.

A CSS supervisor is responsible for ensuring CCTV footage is retained. The primary reason for footage retention policies is to:

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.

Which sensor type is most appropriate for detecting the opening of a door or window in an intrusion detection system?

Answer: Magnetic contact switch

Magnetic contact switches detect the separation of two magnets when a door or window is opened, triggering an alarm.

A security supervisor receives a request to grant a contractor temporary access credentials. The best practice is to:

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.
