Question 1

In CCTV systems, what does 'resolution' expressed in TVL (TV lines) measure?

Accepted Answer

The horizontal detail a camera can capture across the width of the image

Answer

TVL measures horizontal resolution—the number of distinct vertical lines a camera can resolve across the full width of the image, indicating image detail quality.

Question 2

Which access control model grants permissions based on a user's role within an organization rather than individual identity?

Accepted Answer

Role-Based Access Control (RBAC)

Answer

RBAC assigns permissions to roles (e.g., manager, guard, technician) and users inherit those permissions by being assigned to a role, simplifying large-scale permission management.

Question 3

What is the key advantage of fiber optic cable over copper cable for perimeter intrusion detection?

Accepted Answer

Immune to electromagnetic interference and very difficult to tap without detection

Answer

Fiber optic cables transmit light rather than electrical signals, making them immune to EMI, lightning, and virtually impossible to tap without causing a detectable signal disruption.

Question 4

What does 'OSDP' stand for and what is its security relevance?

Accepted Answer

Open Supervised Device Protocol — a secure, bidirectional communication standard for access control readers

Answer

OSDP (Open Supervised Device Protocol) is an access control communication standard that supports AES-128 encryption and bidirectional supervision between readers and controllers.

Question 5

In the context of alarm systems, what is a 'supervisory signal'?

Accepted Answer

A signal indicating a problem with the alarm system itself, such as a low battery or open tamper switch

Answer

A supervisory signal alerts monitoring personnel to a trouble condition in the alarm system itself—such as a low battery, tamper switch activation, or communication failure.
