Surveillance & Monitoring Systems Flashcards

When positioning a fixed security camera to monitor a building entrance, which factor is most important?

Answer: Camera angle and field of view that captures full-face images of persons entering and exiting

Facial recognition and identification require cameras to capture clear, full-face images at the point of entry. This is the primary investigative value of entrance surveillance.

What is a 'blind spot' in a security camera system and why is it a concern?

Answer: An area not covered by any camera, leaving it unmonitored and creating a security vulnerability

Blind spots are unmonitored areas within a facility or property. Criminals and unauthorized persons may exploit blind spots to conduct illegal activities without being recorded.

How should a security officer respond when they observe suspicious behavior on a live camera monitor?

Answer: Immediately notify patrol officers or law enforcement and continue monitoring the situation

Live monitoring requires prompt response. Notifying patrol officers and continuing to monitor allows for an appropriate ground-level response while maintaining situational awareness.

What is the recommended practice for managing recorded security footage to ensure it is available for investigations?

Answer: Establish a retention policy that keeps footage for a minimum number of days and secure storage access

Footage retention policies ensure recordings are available when needed. Industry practice is to retain footage for at least 30 days, with longer retention for incidents.

In what area does Texas law generally restrict the use of security cameras?

Answer: Areas where individuals have a reasonable expectation of privacy, such as restrooms and locker rooms

Recording in areas where people have a reasonable expectation of privacy — such as restrooms, locker rooms, and changing rooms — is illegal in Texas under the invasive visual recording statute.

What is 'video analytics' in the context of modern security monitoring systems?

Answer: Software that automatically analyzes camera footage to detect specific behaviors or anomalies

Video analytics is software that uses algorithms to detect and alert on specific conditions — such as perimeter breaches, loitering, or crowd density — within camera footage.
