Security Technology and Solutions Flashcards

What is the key difference between 'monitored' and 'unmonitored' alarm systems?

Answer: Monitored systems send alerts to a central station; unmonitored only trigger local sirens or notifications

Monitored systems relay alerts to a professional central station that can dispatch help, while unmonitored systems only produce local audible or visual alerts.

A customer asks about 'license plate recognition' (LPR) cameras. What is their primary application?

Answer: Capturing and reading vehicle license plate numbers for access control or forensic use

LPR cameras use optical character recognition to read license plates, enabling automated vehicle access control, blacklist alerts, and forensic investigation.

Which cybersecurity best practice is most critical when deploying IP-connected security cameras?

Answer: Changing default usernames and passwords immediately upon installation

Default credentials on IP cameras are publicly known and are a primary attack vector; changing them immediately is the most fundamental cybersecurity step.

What is a 'request-to-exit' (REX) device used for in an access control door installation?

Answer: Allows a person inside a secured area to exit without using a credential

A REX device (such as a motion sensor or push button on the inside of a door) signals the access control panel to unlock the door for egress without requiring credential presentation.

In cloud-based access control, what is a major advantage over traditional on-premise server-based systems?

Answer: Remote management, automatic software updates, and reduced on-site server hardware costs

Cloud-based access control eliminates the need for on-site servers, provides automatic updates, and enables remote management from any internet-connected device.

Which sensor type is specifically designed to detect the sound frequency of breaking glass?

Answer: Glass break detector

Glass break detectors use microphones tuned to the specific acoustic frequency produced when glass shatters, triggering an alarm on that sound signature.

When a security salesperson discusses 'scalability' of a security system with a customer, what does this mean?

Answer: The system's ability to grow by adding more devices, users, or locations without replacing the core infrastructure

Scalability means the system architecture supports easy expansion—adding cameras, doors, users, or sites—as the customer's needs grow, protecting their investment.
