✍️ Sample CST Questions & Answers
1. Which practice BEST supports the legal defensibility of a surveillance system's footage in litigation?
Access controls, audit logs, and encryption collectively demonstrate that footage has not been altered or accessed improperly, supporting its authenticity and admissibility as evidence.
2. What is the primary function of video analytics in a surveillance system?
Video analytics uses algorithms to automatically analyze video content and detect specific events, behaviors, or objects without continuous human monitoring.
3. A PM task calls for checking the video wall display used in a control room. What is the primary maintenance concern for these displays?
Video wall displays in continuous-use control rooms degrade in pixel uniformity and backlight brightness over time, and heat management must be verified to prevent premature failure.
4. What is the purpose of 'camera tamper detection' in a video analytics system?
Camera tamper detection identifies when a camera has been physically interfered with—such as being covered, repositioned, or defaced—and triggers an immediate alert.
5. What does the term 'credential management' refer to in access control?
Credential management encompasses the entire lifecycle of access credentials — from issuance and assignment to modification and revocation.
6. What does the pixel per foot (PPF) metric measure in surveillance system design?
PPF quantifies how many pixels are available to represent one foot of the scene at a specific distance, directly determining the level of detail captured.
