Security Technology in Courthouses Flashcards

Which type of X-ray imaging technology produces a 3D reconstruction of scanned items, improving detection of concealed threats in carry-on bags?

Answer: Computed Tomography (CT)

CT scanners generate three-dimensional images that allow operators to rotate and examine objects from multiple angles, significantly improving detection accuracy.

In courthouse access control, a 'mantrap' (also called an airlock or sallyport) is designed primarily to:

Answer: Prevent tailgating by allowing only one person through at a time

A mantrap uses two interlocked doors so the first must close and lock before the second opens, preventing unauthorized individuals from piggybacking through.

A courthouse installs a video analytics system that automatically flags loitering near secure entrances. What category of security technology is this?

Answer: Behavioral analytics software

Behavioral analytics software uses algorithms to analyze video feeds and detect patterns—such as loitering or unusual movement—that may indicate a security threat.

When calibrating a walk-through metal detector (WTMD) in a courthouse, the sensitivity setting must balance detection capability against:

Answer: False-positive alarms from innocuous metal objects

Setting sensitivity too high causes frequent false alarms from belt buckles, keys, or medical implants, which reduces throughput and diverts officer attention.

Which communication technology is most commonly used for interoperability between courthouse security staff and external law enforcement agencies during a critical incident?

Answer: Project 25 (P25) land mobile radio

P25 is the federal standard for public safety communications, enabling encrypted, interoperable voice communication across multiple agencies.

A courthouse security officer notices that the CCTV monitor shows a frozen image of an empty hallway but staff report activity in that area. The most likely cause is:

Answer: The video feed has been looped by someone tampering with the system

A looped or replayed video feed—where a recorded still or clip replaces the live stream—is a known technique to defeat surveillance monitoring and indicates tampering.

Passive infrared (PIR) motion detectors in courthouse after-hours security systems trigger based on:

Answer: Changes in infrared radiation emitted by a moving body

PIR sensors detect the infrared energy (heat) naturally emitted by human bodies; motion is sensed when that heat signature moves across the sensor's detection zones.
