Security Technology & Equipment Flashcards

What is an 'intrusion detection system' (IDS) and what types of sensors are commonly used?

Answer: An electronic system that detects unauthorized entry using motion sensors, door/window contacts, glass-break detectors, and vibration sensors

Intrusion detection systems use various sensor types to detect unauthorized entry into a protected area and trigger alarms for security response.

What is a 'key card access control system' and what are its advantages over traditional lock-and-key systems?

Answer: Electronic credentials (cards, fobs, or biometrics) that control door access with an audit trail — advantages include instant deactivation, access level customization, and event logging

Electronic access control systems track who enters which areas and when, can be instantly reprogrammed, and eliminate the risk of physical key duplication.

What is a 'perimeter alarm system' and what is the role of the security officer when it is triggered?

Answer: A system that detects unauthorized breach of the outer boundary of a protected area — officers should respond immediately, assess the breach, and notify supervisors and law enforcement as appropriate

Perimeter alarms detect boundary breaches. Officers respond by assessing the location, determining if the alarm is genuine or false, and taking appropriate action.

What is the significance of cybersecurity for physical security officers working with connected security systems?

Answer: Connected security systems (cameras, access control, alarms) can be compromised by cyberattacks, undermining physical security — officers should follow protocols for protecting system credentials and reporting suspicious activity

Modern security systems are network-connected and can be targeted by cyberattacks. Physical security officers who use these systems must follow cybersecurity best practices.

What is 'GPS tracking' and how might it be used in a security context?

Answer: Global Positioning System technology that tracks the location of vehicles, assets, or personnel in real time — used to track security vehicles, assets, and verify patrol routes

GPS tracking enables real-time location awareness of vehicles and personnel, enhancing coordination and accountability in security operations.

What is a 'license plate recognition' (LPR) system and how is it used in security operations?

Answer: A camera and software system that automatically reads and records vehicle license plates — used to control access to parking areas and identify vehicles associated with incidents or persons of interest

LPR systems automatically read plates and can compare them against databases of vehicles of interest, enabling automated access control and investigative assistance.
